How to distribute DEXT during development and to the public
To learn how to develop/distribute a DriverKit driver (DEXT) and a UserClient app correctly, I am trying to run the following sample dext and app. https://developer.apple.com/documentation/driverkit/communicating-between-a-driverkit-extension-and-a-client-app?language=objc I walked throught steps in README.md included in the project and faced issues. First, I referred the "Configure the Sample Code Project" section in the README.md and configured the sample code project to build with automatic signing. I could run the app and activate the dext successfully and made sure the app could communicate with the dext. Next, I tried the manual signing. I followed steps described in the "Configure the Sample Code Project" section carefully. The following entitlements has already been assigned to my team account. DriverKit Allow Any UserClient Access DriverKit USB Transport - VendorID DriverKit I could build both app and dext and could run the app. However, when I clicked the "Install Dext" button to activate the dext, I got the following error: sysex didFailWithError: extension category returned error Am I missing something? I would also like to know detailed steps to publicly distribute my dext and app using our Developer ID Application Certificate, as README.md only shows how to configure the project for development. Xcode version: 16.3 (16E140) Development OS: macOS 15.5 (24F74) Target OS: macOS 15.5 (24F74)

Test my app without ADP membership
Hello community, I'm new here, so please excuse my blunt question. I'm trying to understand how everything works and the logic behind it. I have an idea for an app which requires the FamilyControl entitlement. Now I am not sure if the idea even works, so I wanted to test it on my own device. Am I correct, that I cannot even test an App with such entitlements without paying for the ADP? Not even on my own device? I completely understand I need to be a member in the ADP if I want to distribute my app, but I'm not there, yet, and I just want to do a proof-of-concept. I thought I can't be the first one with that question, but couldn't find a past topic on this, so I'm posting it. Regards, Niklas

App Sandbox & Missing Symbols for Nested PyInstaller App Bundle
Hi Developers, I'm encountering persistent validation errors in Xcode 16.3 (16E140) on macOS 15.4.1 (24E263) with M1 when archiving and distributing a macOS app (Developer ID signing + notarization). App Structure: A native Swift/Obj-C wrapper app that launches a nested .app inside its Resources. The nested app is built with PyInstaller and includes: A Python core Custom C++ binaries Many bundled .so libraries (e.g., from OpenCV, PyQt/PySide) Issues During Validation: App Sandbox Not Enabled Error: App Sandbox missing for NestedApp.app/Contents/MacOS/NestedExecutable. Question: For Developer ID (not App Store), is sandboxing strictly required for nested PyInstaller apps? If the wrapper is sandboxed, must the nested app be as well? Given the PyInstaller app's nature (requiring broad system access), how should entitlements be managed? Upload Symbols Failed Errors for missing .dSYM files for: The nested app’s executable Custom C++ binaries .so files (OpenCV, PyQt, etc.) These are either third-party or built without DWARF data, making .dSYM generation impractical post-build. Question: Are these symbol errors critical for Developer ID notarization (not App Store)? Can notarization succeed despite them? Is lack of symbol upload a known limitation with PyInstaller apps? Any best practices?

notary tool consistently delay for 1 of my app even it already accepted multiple times
Hi, I recently got a consistent delay from notary tool. I have viewed all your suggestions and understand that it "occasionally" will have further review and take longer time, but then it will be faster. However, in my case, my app although is accepted many times. It is still significantly delay. It is a native macOS app called ConniePad. Whenever I submit, it took me 2 days or more to finish notarise, which significantly affect my business. Could you please have a look on it.

Gatekeeper rejects notarized app ("Unnotarized Developer ID") when using necessary entitlements
Hello everyone, I'm hoping to get some guidance on a frustrating codesigning issue. I have a macOS application that successfully completes the entire notarization and stapling process, but it is still rejected by Gatekeeper during the final verification step. The rejection only happens when I apply the entitlements that I believe are necessary for my app's functionality. The application is built with PyInstaller and has the following components: A main executable written in Python. A bundled Tcl/Tk instance for the GUI. Embedded Playwright components, which include the Node.js runtime and a full Chromium browser instance. These are located deep inside the .app bundle. The Problem The core of my application relies on Playwright to perform some automated tasks, and its bundled Chromium browser requires specific entitlements to function under the Hardened Runtime. Specifically, it needs com.apple.security.cs.allow-jit and com.apple.security.cs.allow-unsigned-executable-memory. My signing process is as follows: Prepare Entitlements: I use two separate .plist files: main_app_entitlements.plist: This is for the main Python executable and only contains com.apple.security.cs.allow-jit. jit_helper_entitlements.plist: This is for the node and Chromium Helper executables within the Playwright framework. It contains both com.apple.security.cs.allow-jit and com.apple.security.cs.allow-unsigned-executable-memory. Inside-Out Signing: I perform a deep signing process. I find all binaries, dylibs, and frameworks, sort them by path length (deepest first), and sign each one individually with the appropriate entitlements. The main .app bundle is signed last. Notarization: I zip the .app bundle and submit it using xcrun notarytool submit --wait. The tool reports a successful notarization every time. Stapling: I use xcrun stapler staple on the .app bundle, and it confirms that the ticket was successfully stapled. The point of failure The final step is to verify the result with spctl: spctl --assess --type execute --verbose --ignore-cache "MyApp.app" This is where it fails. The output is: MyApp.app: rejected source=Unnotarized Developer ID This "Unnotarized Developer ID" message is confusing because xcrun notarytool and stapler both report complete success. The crucial detail If I run the entire process without any entitlements—just signing with the Hardened Runtime enabled—the final spctl assessment passes. However, the application then crashes at runtime as soon as it tries to use Playwright, which is expected since the browser helpers are missing their required JIT entitlements. My question Is there a known issue where using com.apple.security.cs.allow-jit or com.apple.security.cs.allow-unsigned-executable-memory on nested helper executables can invalidate an otherwise successful notarization? Is my strategy of applying different, granular entitlements to different executables within the same app bundle correct? Could the issue be related to how or when these entitlements are applied during an "inside-out" signing process? Is there a better way to structure the signing of these complex components? I'm confident the notarization itself is working, but it seems Gatekeeper's local assessment is stricter and is being tripped up by my entitlement configuration. Thank you in advance for any help or suggestions you can provide

Provisioning profile doesn't support the External Link Account capability
Hello, i have a problem. From one day to another i get following error (I never experienced this error with the same profile before) while trying to build and release my app via fastlane: exportArchive Provisioning profile "" doesn't support the External Link Account capability. Looking in the App developer website, it seems, that the existing and valid profile includes this capability. On the other side, inspecting the profile via xcode profile download, there is no hint that this capability is enabled. Any suggestions? Thanks!

Constructing a filesystem sandbox, how to disable file events
I'm working on a build system similar to Bazel where each build action runs in a sandbox. The sandbox contains only the files that the user defined as input to ensure that the build action doesn't have any implicit dependencies. Bazel achieves this by creating a "symlink forest" to the original source files. This works, but I have observed fseventsd using significant CPU during a Bazel build, presumably because of all the symlinks that get created. Is there a way to disable file events for a directory or a volume? The "File System Events Programming Guide" in the Documentation Archive mentions placing an empty file named no_log in the .fseventsd directory at the root of the volume, but when testing on macOS 15.5 with APFS that appears to no longer work. Related, is a "symlink forest" the best way to create a sandbox like this? Or is there a different method one can use to provide a view of a subset of the files in a directory tree? I read up on the App Sandbox but that seems too coarse grained. Something like Linux's overlayfs would work well, and maybe one can achieve a similar functionality with firmlinks? Curious about folks thoughts here. Thanks in advance!

Use 3rd party USB drivers in iPadOS?
Hi everyone, I'm working with a third party to integrate their USB driver into our app and I'm wondering if iPadOS supports bundling a prebuilt .systemextension file with the entitlement com.apple.developer.system-extension.redistributable into our app that has the com.apple.developer.driverkit.communicates-with-drivers entitlement? If not, is there a way to bundle a third party USB driver into our iPad app?

Definitive Rules for Using Secure Enclave on MacOS
Can someone tell me the applications requirements for using the secure enclave on MacOS? Does the application need to be signed with the secure-enclave entitlement in order to use it? Since this is a restricted entitlement, does my App ID need approval to use it from Apple? Currently I'm building in XCode 16 on Sequoia (15.5) using developer signing. My application is a C/C++ daemon running as plist out of /Library/LaunchDaemons. I have also built it as an application using the instructions here but this has not lead to a solution: https://developer.apple.com/documentation/xcode/signing-a-daemon-with-a-restricted-entitlement/ When I run my application from the command line via sudo signed but without the secure-enclave entitlement enabled in my entitlements file it runs. The first call to: SecAccessControlRef access = SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, kSecAccessControlPrivateKeyUsage, &error); succeeds without error. The call to create the key using: SecKeyRef privateKey = SecKeyCreateRandomKey(attributes, &error); then fails with error: (OSStatus error -50 - Failed to generate keypair) Here are the setup attributes (keySize = 256): CFDictionarySetValue(attributes, kSecAttrKeyType, kSecAttrKeyTypeECSECPrimeRandom); CFDictionarySetValue(attributes, kSecAttrKeySizeInBits, keySize); CFDictionarySetValue(attributes, kSecAttrLabel, keyName); CFDictionarySetValue(attributes, kSecAttrApplicationTag, keyLabel); CFDictionarySetValue(attributes, kSecAttrTokenID, kSecAttrTokenIDSecureEnclave); // Store in the Secure Enclave CFDictionarySetValue(attributes, kSecAttrKeyClass, kSecAttrKeyClassPrivate); CFDictionarySetValue(attributes, kSecAttrAccessControl, access); CFDictionarySetValue(attributes, kSecAttrIsPermanent, kCFBooleanTrue); // persist key across app restarts and reboots CFDictionarySetValue(attributes, kSecAttrCanEncrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrCanDecrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrAccessible, kSecAttrAccessibleWhenUnlockedThisDeviceOnly); CFDictionarySetValue(attributes, kSecReturnPersistentRef, kCFBooleanTrue); When I run the application signed and include the "com.apple.developer.secure-enclave" in my entitlements file it crashes at startup. I believe this is to be expected based on above. How do I proceed such that my application can use the secure enclave correctly?

Does NSXPCConnection.setCodeSigningRequirement perform dynamic code signature checks?
To validate incoming XPC connections from other executables, we perform SecCode checks for the dynamic signature of the connection (kSecCSDynamicInformation). Reading the setCodeSigningRequirement(_:) function documentation it appears to perform only static signing checks, is that so? If we use setCodeSigningRequirement(:) function in our listener(:, shouldAcceptNewConnection:) do we still need to check the dynamic information to be properly secure?

After submitting the DMG signature, a prompt indicating that it comes from an unidentified developer still appears when downloading and installing.
我是一名开发人员。除了App Store,我们公司的官方网站也是软件下载的一种方式。DMG签名提交后,通过网站下载安装软件时,仍然有提示说来自身份不明的开发者。您能告诉我如何解决这个问题吗?如果你能用中文回复就最好了。

AppStore submission for Ruby/Glimmer app on MacOS without Xcode
Background I've repeatedly run into codesigning (and missing provisioning profile) issues for my Ruby/Glimmer app and am looking for ways to troubleshoot this outside of Xcode. The app structure is as follows: PATHmanager.app └── Contents ├── Info.plist ├── MacOS │   └── PATHmanager ├── PkgInfo ├── Resources │   └── AppIcon.icns ├── _CodeSignature │   └── CodeResources └── embedded.provisionprofile Architecture I have a Mac mini Apple M2 Pro with macOS Ventura 13.4. Xcode is not used directly, but the underlying command line tools (e.g., codesign, productbuild, pkgutil, xcrun) are run from a custom Ruby script. xcodebuild -version Xcode 14.3.1 Build version 14E300c Questions Is the .app directory and file structure/naming sufficient? If not, can you point me in the direction of a minimal example that does not use Xcode? Info.plist is an XML text document (not binary), which I believe is in an acceptable format, but how do I lint this file and determine if it contains all of the necessary key/value pairs? <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>en</string> <key>CFBundleDisplayName</key> <string>PATH manager</string> <key>CFBundleExecutable</key> <string>PATHmanager</string> <key>CFBundleIconFile</key> <string>AppIcon.icns</string> <key>CFBundleIdentifier</key> <string>com.chipcastle.pathmanager</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>PATHmanager</string> <key>CFBundlePackageType</key> <string>APPL</string> <key>CFBundleShortVersionString</key> <string>1.15</string> <key>CFBundleSupportedPlatforms</key> <array> <string>MacOSX</string> </array> <key>CFBundleVersion</key> <string>1.15</string> <key>ITSAppUsesNonExemptEncryption</key> <false/> <key>LSApplicationCategoryType</key> <string>public.app-category.developer-tools</string> <key>LSMinimumSystemVersion</key> <string>12.0</string> <key>LSUIElement</key> <false/> <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> <key>NSHumanReadableCopyright</key> <string>© 2025 Chip Castle Dot Com, Inc.</string> <key>NSMainNibFile</key> <string>MainMenu</string> <key>NSPrincipalClass</key> <string>NSApplication</string> </dict> </plist> PATHmanager is a Mach-O 64-bit executable arm64 file created by using Tebako. Does this executable need to be codesigned, or is codesigning the .app folder sufficient? Does the .app directory need an entitlements file? Here's how I codesign it: codesign --deep --force --verify --verbose=4 --options runtime --timestamp --sign 'Apple Distribution: Chip Castle Dot Com, Inc. (BXN9N7MNU3)' '/Users/chip/Desktop/distribution/PATHmanager.app' Does the PATHmanager binary need an entitlements file? Here's how I codesign it: codesign --deep --force --verify --verbose=4 --options runtime --timestamp --entitlements '/Users/chip/Desktop/PATHmanager.entitlements' --sign 'Apple Distribution: Chip Castle Dot Com, Inc. (BXN9N7MNU3)' '/Users/chip/Desktop/distribution/PATHmanager.app/Contents/MacOS/PATHmanager' How can I verify what entitlements, if any, are required for codesigning the binary? The PATHmanager.entitlements file is an XML text file containing only the following: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> </dict> </plist> Is the embedded.provisionprofile necessary, and if so, how do I know determine if it matches the certificate or entitlements that I'm using? Additionally, is it named and located properly? I submitted this to the AppStore several weeks ago and the reviewer reported that the executable would not load on their machine (even though it worked on mine.) Is it better for me to release via TestFlight for testing, and if so, do I need to following a separate process for codesigning (i.e., using different entitlements, profiles, certs, etc) when doing so? I've been playing whack-a-mole with this for too long to mention and am hoping to nail down a better deployment flow, so any suggestions for improvement will be greatly appreciated. Thank you in advance.

Code Signing - Invalid Signature - Special Characters in Name, Team Name and Address
I was trying to put my game to test flight. I would test features like ads and in-app-purchases, then put on the Appstore(release). The game already works on Ipad. For test flight, the "automatically manage signing" option was enabled. Then I pressed the "archive" button. Built succeeded. Then I clicked the distribute button. That time, I had an error. "Upload failed, Invalid signature, App is not properly signed". I researched, and found special characters in name, team name and address can make errors. My name, address and team name have special characters(turkish). If it will be resolved, I want to re-write(fix) my name, team name and address. I already tried to change my name, team name and address from apple developer website but failed. They are asking a document of my identity of my new name but I didn't changed my name and address. Overall, there aren't any other facts that cause this issue as I know. If I send my current, unchanged identity and home address, could they allow to change(fix) them? On Console Log: DangerNo.app/DangerNo: ID : 6cfa13a9-685c-4df9-86dd-7506d67be8c5 DangerNo.app/Frameworks/UnityFramework.framework/UnityFramework: ID : 2b63aacc-9caf-453c-913f-bae0db14d363 My App ID : 6744022885 Error : Invalid Binary rejection email indicating a corrupted code signature was detected. Explanation : Invalid Signature - Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target.

Notarising two builds of the same app
I have built my application for arm and x64 so I have two files called DeepSkyStacker.app in different directories. I have followed the instructions to notarise the arm version of the app, but an concerned about what I should do to notarise the other one - do I just zip that up and then run: xcrun notarytool submit "DeepSkyStacker.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple DeepSkyStacker.app again or will that mess everything up? Related to that can I use the Notary Profile I created for DeepSkyStacker to notarise other apps that are part of the same product (DeepSkyStackerLive and DeepSkyStackerCL)?? Thanks David

Inquiry about CarPlay Entitlements Application - Black Box Integration for Device Settings & Communication - No Response After 7 Days
Hi everyone, I applied for CarPlay Entitlements on [Date 04. 26, 2024] using CarPlay is Case ID "13045151". I haven't received any updates or responses regarding my application yet. It's been 7 days since the application. My service requires CarPlay integration with a Black Box device. The primary purpose of this integration is to allow users to configure device settings through CarPlay. Furthermore, we plan to utilize the "Communication" category of Entitlements to notify users of parking incidents detected by the Black Box device while parked. This functionality is crucial for alerting drivers to potential issues affecting their vehicles. Could anyone share their experience with the typical turnaround time for CarPlay Entitlements, especially for applications involving device integration and the "Communication" category? Is this delay normal? Is there any way to check the application status or contact the appropriate team to inquire about its progress? Thank you for any insights or advice you can provide! Sincerely,

How to distribute DEXT during development and to the public
To learn how to develop/distribute a DriverKit driver (DEXT) and a UserClient app correctly, I am trying to run the following sample dext and app. https://developer.apple.com/documentation/driverkit/communicating-between-a-driverkit-extension-and-a-client-app?language=objc I walked throught steps in README.md included in the project and faced issues. First, I referred the "Configure the Sample Code Project" section in the README.md and configured the sample code project to build with automatic signing. I could run the app and activate the dext successfully and made sure the app could communicate with the dext. Next, I tried the manual signing. I followed steps described in the "Configure the Sample Code Project" section carefully. The following entitlements has already been assigned to my team account. DriverKit Allow Any UserClient Access DriverKit USB Transport - VendorID DriverKit I could build both app and dext and could run the app. However, when I clicked the "Install Dext" button to activate the dext, I got the following error: sysex didFailWithError: extension category returned error Am I missing something? I would also like to know detailed steps to publicly distribute my dext and app using our Developer ID Application Certificate, as README.md only shows how to configure the project for development. Xcode version: 16.3 (16E140) Development OS: macOS 15.5 (24F74) Target OS: macOS 15.5 (24F74)

Test my app without ADP membership
Hello community, I'm new here, so please excuse my blunt question. I'm trying to understand how everything works and the logic behind it. I have an idea for an app which requires the FamilyControl entitlement. Now I am not sure if the idea even works, so I wanted to test it on my own device. Am I correct, that I cannot even test an App with such entitlements without paying for the ADP? Not even on my own device? I completely understand I need to be a member in the ADP if I want to distribute my app, but I'm not there, yet, and I just want to do a proof-of-concept. I thought I can't be the first one with that question, but couldn't find a past topic on this, so I'm posting it. Regards, Niklas

App Sandbox & Missing Symbols for Nested PyInstaller App Bundle
Hi Developers, I'm encountering persistent validation errors in Xcode 16.3 (16E140) on macOS 15.4.1 (24E263) with M1 when archiving and distributing a macOS app (Developer ID signing + notarization). App Structure: A native Swift/Obj-C wrapper app that launches a nested .app inside its Resources. The nested app is built with PyInstaller and includes: A Python core Custom C++ binaries Many bundled .so libraries (e.g., from OpenCV, PyQt/PySide) Issues During Validation: App Sandbox Not Enabled Error: App Sandbox missing for NestedApp.app/Contents/MacOS/NestedExecutable. Question: For Developer ID (not App Store), is sandboxing strictly required for nested PyInstaller apps? If the wrapper is sandboxed, must the nested app be as well? Given the PyInstaller app's nature (requiring broad system access), how should entitlements be managed? Upload Symbols Failed Errors for missing .dSYM files for: The nested app’s executable Custom C++ binaries .so files (OpenCV, PyQt, etc.) These are either third-party or built without DWARF data, making .dSYM generation impractical post-build. Question: Are these symbol errors critical for Developer ID notarization (not App Store)? Can notarization succeed despite them? Is lack of symbol upload a known limitation with PyInstaller apps? Any best practices?

notary tool consistently delay for 1 of my app even it already accepted multiple times
Hi, I recently got a consistent delay from notary tool. I have viewed all your suggestions and understand that it "occasionally" will have further review and take longer time, but then it will be faster. However, in my case, my app although is accepted many times. It is still significantly delay. It is a native macOS app called ConniePad. Whenever I submit, it took me 2 days or more to finish notarise, which significantly affect my business. Could you please have a look on it.

Gatekeeper rejects notarized app ("Unnotarized Developer ID") when using necessary entitlements
Hello everyone, I'm hoping to get some guidance on a frustrating codesigning issue. I have a macOS application that successfully completes the entire notarization and stapling process, but it is still rejected by Gatekeeper during the final verification step. The rejection only happens when I apply the entitlements that I believe are necessary for my app's functionality. The application is built with PyInstaller and has the following components: A main executable written in Python. A bundled Tcl/Tk instance for the GUI. Embedded Playwright components, which include the Node.js runtime and a full Chromium browser instance. These are located deep inside the .app bundle. The Problem The core of my application relies on Playwright to perform some automated tasks, and its bundled Chromium browser requires specific entitlements to function under the Hardened Runtime. Specifically, it needs com.apple.security.cs.allow-jit and com.apple.security.cs.allow-unsigned-executable-memory. My signing process is as follows: Prepare Entitlements: I use two separate .plist files: main_app_entitlements.plist: This is for the main Python executable and only contains com.apple.security.cs.allow-jit. jit_helper_entitlements.plist: This is for the node and Chromium Helper executables within the Playwright framework. It contains both com.apple.security.cs.allow-jit and com.apple.security.cs.allow-unsigned-executable-memory. Inside-Out Signing: I perform a deep signing process. I find all binaries, dylibs, and frameworks, sort them by path length (deepest first), and sign each one individually with the appropriate entitlements. The main .app bundle is signed last. Notarization: I zip the .app bundle and submit it using xcrun notarytool submit --wait. The tool reports a successful notarization every time. Stapling: I use xcrun stapler staple on the .app bundle, and it confirms that the ticket was successfully stapled. The point of failure The final step is to verify the result with spctl: spctl --assess --type execute --verbose --ignore-cache "MyApp.app" This is where it fails. The output is: MyApp.app: rejected source=Unnotarized Developer ID This "Unnotarized Developer ID" message is confusing because xcrun notarytool and stapler both report complete success. The crucial detail If I run the entire process without any entitlements—just signing with the Hardened Runtime enabled—the final spctl assessment passes. However, the application then crashes at runtime as soon as it tries to use Playwright, which is expected since the browser helpers are missing their required JIT entitlements. My question Is there a known issue where using com.apple.security.cs.allow-jit or com.apple.security.cs.allow-unsigned-executable-memory on nested helper executables can invalidate an otherwise successful notarization? Is my strategy of applying different, granular entitlements to different executables within the same app bundle correct? Could the issue be related to how or when these entitlements are applied during an "inside-out" signing process? Is there a better way to structure the signing of these complex components? I'm confident the notarization itself is working, but it seems Gatekeeper's local assessment is stricter and is being tripped up by my entitlement configuration. Thank you in advance for any help or suggestions you can provide

Provisioning profile doesn't support the External Link Account capability
Hello, i have a problem. From one day to another i get following error (I never experienced this error with the same profile before) while trying to build and release my app via fastlane: exportArchive Provisioning profile "" doesn't support the External Link Account capability. Looking in the App developer website, it seems, that the existing and valid profile includes this capability. On the other side, inspecting the profile via xcode profile download, there is no hint that this capability is enabled. Any suggestions? Thanks!

Constructing a filesystem sandbox, how to disable file events
I'm working on a build system similar to Bazel where each build action runs in a sandbox. The sandbox contains only the files that the user defined as input to ensure that the build action doesn't have any implicit dependencies. Bazel achieves this by creating a "symlink forest" to the original source files. This works, but I have observed fseventsd using significant CPU during a Bazel build, presumably because of all the symlinks that get created. Is there a way to disable file events for a directory or a volume? The "File System Events Programming Guide" in the Documentation Archive mentions placing an empty file named no_log in the .fseventsd directory at the root of the volume, but when testing on macOS 15.5 with APFS that appears to no longer work. Related, is a "symlink forest" the best way to create a sandbox like this? Or is there a different method one can use to provide a view of a subset of the files in a directory tree? I read up on the App Sandbox but that seems too coarse grained. Something like Linux's overlayfs would work well, and maybe one can achieve a similar functionality with firmlinks? Curious about folks thoughts here. Thanks in advance!

Use 3rd party USB drivers in iPadOS?
Hi everyone, I'm working with a third party to integrate their USB driver into our app and I'm wondering if iPadOS supports bundling a prebuilt .systemextension file with the entitlement com.apple.developer.system-extension.redistributable into our app that has the com.apple.developer.driverkit.communicates-with-drivers entitlement? If not, is there a way to bundle a third party USB driver into our iPad app?

Definitive Rules for Using Secure Enclave on MacOS
Can someone tell me the applications requirements for using the secure enclave on MacOS? Does the application need to be signed with the secure-enclave entitlement in order to use it? Since this is a restricted entitlement, does my App ID need approval to use it from Apple? Currently I'm building in XCode 16 on Sequoia (15.5) using developer signing. My application is a C/C++ daemon running as plist out of /Library/LaunchDaemons. I have also built it as an application using the instructions here but this has not lead to a solution: https://developer.apple.com/documentation/xcode/signing-a-daemon-with-a-restricted-entitlement/ When I run my application from the command line via sudo signed but without the secure-enclave entitlement enabled in my entitlements file it runs. The first call to: SecAccessControlRef access = SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, kSecAccessControlPrivateKeyUsage, &error); succeeds without error. The call to create the key using: SecKeyRef privateKey = SecKeyCreateRandomKey(attributes, &error); then fails with error: (OSStatus error -50 - Failed to generate keypair) Here are the setup attributes (keySize = 256): CFDictionarySetValue(attributes, kSecAttrKeyType, kSecAttrKeyTypeECSECPrimeRandom); CFDictionarySetValue(attributes, kSecAttrKeySizeInBits, keySize); CFDictionarySetValue(attributes, kSecAttrLabel, keyName); CFDictionarySetValue(attributes, kSecAttrApplicationTag, keyLabel); CFDictionarySetValue(attributes, kSecAttrTokenID, kSecAttrTokenIDSecureEnclave); // Store in the Secure Enclave CFDictionarySetValue(attributes, kSecAttrKeyClass, kSecAttrKeyClassPrivate); CFDictionarySetValue(attributes, kSecAttrAccessControl, access); CFDictionarySetValue(attributes, kSecAttrIsPermanent, kCFBooleanTrue); // persist key across app restarts and reboots CFDictionarySetValue(attributes, kSecAttrCanEncrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrCanDecrypt, kCFBooleanTrue); CFDictionarySetValue(attributes, kSecAttrAccessible, kSecAttrAccessibleWhenUnlockedThisDeviceOnly); CFDictionarySetValue(attributes, kSecReturnPersistentRef, kCFBooleanTrue); When I run the application signed and include the "com.apple.developer.secure-enclave" in my entitlements file it crashes at startup. I believe this is to be expected based on above. How do I proceed such that my application can use the secure enclave correctly?

Does NSXPCConnection.setCodeSigningRequirement perform dynamic code signature checks?
To validate incoming XPC connections from other executables, we perform SecCode checks for the dynamic signature of the connection (kSecCSDynamicInformation). Reading the setCodeSigningRequirement(_:) function documentation it appears to perform only static signing checks, is that so? If we use setCodeSigningRequirement(:) function in our listener(:, shouldAcceptNewConnection:) do we still need to check the dynamic information to be properly secure?

After submitting the DMG signature, a prompt indicating that it comes from an unidentified developer still appears when downloading and installing.
我是一名开发人员。除了App Store,我们公司的官方网站也是软件下载的一种方式。DMG签名提交后,通过网站下载安装软件时,仍然有提示说来自身份不明的开发者。您能告诉我如何解决这个问题吗?如果你能用中文回复就最好了。

AppStore submission for Ruby/Glimmer app on MacOS without Xcode
Background I've repeatedly run into codesigning (and missing provisioning profile) issues for my Ruby/Glimmer app and am looking for ways to troubleshoot this outside of Xcode. The app structure is as follows: PATHmanager.app └── Contents ├── Info.plist ├── MacOS │   └── PATHmanager ├── PkgInfo ├── Resources │   └── AppIcon.icns ├── _CodeSignature │   └── CodeResources └── embedded.provisionprofile Architecture I have a Mac mini Apple M2 Pro with macOS Ventura 13.4. Xcode is not used directly, but the underlying command line tools (e.g., codesign, productbuild, pkgutil, xcrun) are run from a custom Ruby script. xcodebuild -version Xcode 14.3.1 Build version 14E300c Questions Is the .app directory and file structure/naming sufficient? If not, can you point me in the direction of a minimal example that does not use Xcode? Info.plist is an XML text document (not binary), which I believe is in an acceptable format, but how do I lint this file and determine if it contains all of the necessary key/value pairs? <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>en</string> <key>CFBundleDisplayName</key> <string>PATH manager</string> <key>CFBundleExecutable</key> <string>PATHmanager</string> <key>CFBundleIconFile</key> <string>AppIcon.icns</string> <key>CFBundleIdentifier</key> <string>com.chipcastle.pathmanager</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>PATHmanager</string> <key>CFBundlePackageType</key> <string>APPL</string> <key>CFBundleShortVersionString</key> <string>1.15</string> <key>CFBundleSupportedPlatforms</key> <array> <string>MacOSX</string> </array> <key>CFBundleVersion</key> <string>1.15</string> <key>ITSAppUsesNonExemptEncryption</key> <false/> <key>LSApplicationCategoryType</key> <string>public.app-category.developer-tools</string> <key>LSMinimumSystemVersion</key> <string>12.0</string> <key>LSUIElement</key> <false/> <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> <key>NSHumanReadableCopyright</key> <string>© 2025 Chip Castle Dot Com, Inc.</string> <key>NSMainNibFile</key> <string>MainMenu</string> <key>NSPrincipalClass</key> <string>NSApplication</string> </dict> </plist> PATHmanager is a Mach-O 64-bit executable arm64 file created by using Tebako. Does this executable need to be codesigned, or is codesigning the .app folder sufficient? Does the .app directory need an entitlements file? Here's how I codesign it: codesign --deep --force --verify --verbose=4 --options runtime --timestamp --sign 'Apple Distribution: Chip Castle Dot Com, Inc. (BXN9N7MNU3)' '/Users/chip/Desktop/distribution/PATHmanager.app' Does the PATHmanager binary need an entitlements file? Here's how I codesign it: codesign --deep --force --verify --verbose=4 --options runtime --timestamp --entitlements '/Users/chip/Desktop/PATHmanager.entitlements' --sign 'Apple Distribution: Chip Castle Dot Com, Inc. (BXN9N7MNU3)' '/Users/chip/Desktop/distribution/PATHmanager.app/Contents/MacOS/PATHmanager' How can I verify what entitlements, if any, are required for codesigning the binary? The PATHmanager.entitlements file is an XML text file containing only the following: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> </dict> </plist> Is the embedded.provisionprofile necessary, and if so, how do I know determine if it matches the certificate or entitlements that I'm using? Additionally, is it named and located properly? I submitted this to the AppStore several weeks ago and the reviewer reported that the executable would not load on their machine (even though it worked on mine.) Is it better for me to release via TestFlight for testing, and if so, do I need to following a separate process for codesigning (i.e., using different entitlements, profiles, certs, etc) when doing so? I've been playing whack-a-mole with this for too long to mention and am hoping to nail down a better deployment flow, so any suggestions for improvement will be greatly appreciated. Thank you in advance.

Code Signing - Invalid Signature - Special Characters in Name, Team Name and Address
I was trying to put my game to test flight. I would test features like ads and in-app-purchases, then put on the Appstore(release). The game already works on Ipad. For test flight, the "automatically manage signing" option was enabled. Then I pressed the "archive" button. Built succeeded. Then I clicked the distribute button. That time, I had an error. "Upload failed, Invalid signature, App is not properly signed". I researched, and found special characters in name, team name and address can make errors. My name, address and team name have special characters(turkish). If it will be resolved, I want to re-write(fix) my name, team name and address. I already tried to change my name, team name and address from apple developer website but failed. They are asking a document of my identity of my new name but I didn't changed my name and address. Overall, there aren't any other facts that cause this issue as I know. If I send my current, unchanged identity and home address, could they allow to change(fix) them? On Console Log: DangerNo.app/DangerNo: ID : 6cfa13a9-685c-4df9-86dd-7506d67be8c5 DangerNo.app/Frameworks/UnityFramework.framework/UnityFramework: ID : 2b63aacc-9caf-453c-913f-bae0db14d363 My App ID : 6744022885 Error : Invalid Binary rejection email indicating a corrupted code signature was detected. Explanation : Invalid Signature - Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target.

Notarising two builds of the same app
I have built my application for arm and x64 so I have two files called DeepSkyStacker.app in different directories. I have followed the instructions to notarise the arm version of the app, but an concerned about what I should do to notarise the other one - do I just zip that up and then run: xcrun notarytool submit "DeepSkyStacker.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple DeepSkyStacker.app again or will that mess everything up? Related to that can I use the Notary Profile I created for DeepSkyStacker to notarise other apps that are part of the same product (DeepSkyStackerLive and DeepSkyStackerCL)?? Thanks David

Inquiry about CarPlay Entitlements Application - Black Box Integration for Device Settings & Communication - No Response After 7 Days
Hi everyone, I applied for CarPlay Entitlements on [Date 04. 26, 2024] using CarPlay is Case ID "13045151". I haven't received any updates or responses regarding my application yet. It's been 7 days since the application. My service requires CarPlay integration with a Black Box device. The primary purpose of this integration is to allow users to configure device settings through CarPlay. Furthermore, we plan to utilize the "Communication" category of Entitlements to notify users of parking incidents detected by the Black Box device while parked. This functionality is crucial for alerting drivers to potential issues affecting their vehicles. Could anyone share their experience with the typical turnaround time for CarPlay Entitlements, especially for applications involving device integration and the "Communication" category? Is this delay normal? Is there any way to check the application status or contact the appropriate team to inquire about its progress? Thank you for any insights or advice you can provide! Sincerely,
