Disabling Hardened Runtime For Ad Hoc Signing Only
How can I disable Hardened Runtime in Xcode only when signing ad hoc? If I make a new project, Xcode will say Disabling hardened runtime with ad-hoc codesigning. at the beginning of the build logs. However, somehow my project isn't doing this -- it's still hardening the runtime when ad-hoc signing. What should I do to debug this?

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?

GateKeeper rejects application bundles with a file name with an NFC/NFD problem by copying with Finder
I made a macOS application using Swift Package and distributed it in dmg format through Apple Notary service. However, we received a report from a user that it can be launched from a disk image mounted from dmg, but when copied to /Applications, the app is broken and does not start. I looked into why this happened, I noticed that the codesign command returned different results when copying the application bundle and /Applications on the volume mounted dmg with Finder. Mounted dmg: OK ❯ codesign --verify --deep --verbose /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: valid on disk /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: satisfies its Designated Requirement Copied by Finder: Bad codesign reports that there are 148 added/missing files. ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: a sealed resource is missing or invalid file added: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) file missing: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) Copied by ditto: OK ❯ ditto /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: valid on disk /Applications/azoo-key-skkserv.app: satisfies its Designated Requirement I made a simple macOS application to explain this problem in an easy-to-understand way. You can download dmg in github releases, mount dmg, copy it in the Finder, and check if there is a problem by running the codesign command. https://github.com/mtgto/example-utf8-mac-notarization As a result, I learned the following two things. Occurs only with resources with file names whose values change due to NFC/NFD normalization No problems occur with the resources of the application itself. Generated by the Swift Package resources that the application depends on I think this is a problem with Finder or Gatekeeper.

"The signature of the binary is invalid" macOS App Notarization Issue
After sending the app archive to apple notarization services, I received the following error: "The signature of the binary is invalid". This error is shown for both the arm64 and x86_64 builds of the app. Some details about the project: I have been able to notarize the app in the past, with the latest successful notarization at the start of October. The organization does have a valid developer membership. The app has no new dependencies since the last successful notarization. The project uses automatic managed signing (no visible errors in xcode). What has changed in app and development environment since the last notarization: Updated macOS to macOS 15. Updated to use new Xcode version (16) The organizations membership did expire for a bit, but is now valid. Changed apps target macOS version from 12.3 -> 13.5. What I've tried to debug / resolve this issue: Clean build folder and re-create archive. Waiting a period of time and retrying the notarization. Toggling 'automatic managed signing' off and on. Tried to look through profiles, provisions, certs to see any issues. Debug the issue with 'codesign -vvv --deep --strict /path/to/binary/or/bundle' CLI command (output said binary was valid). (https://developer.apple.com/documentation/security/resolving-common-notarization-issues) Going back to last successful notarized commit and re-notarizing from that point, but that failed as well (changed version number). Reverted a change of increasing the target macOS version (12.3 -> 13.5). Compare failed notarization app's info.plist to previous info.plist for any obvious errors. I tried to install the previous Xcode version, but it seems to be incompatible with macOS 15. Tried looking online for any other options, but only found a couple similar issues and the suggestions I already tried. I can provide further information if needed.

Certificate Revocation Impact
Background We are using a Developer ID application certificate to sign our application. We lost the private key and we need to revoke it before we can receive a new one. Per documentation (https://developer.apple.com/support/certificates/), I know that previously installed applications will still be able to run, but new installations will not be able to work. I want to confirm what will happen when we revoke the certificate so we know how to prepare customers for this upcoming change. Questions Will existing installations of the application receive a notice that the certificate has been revoked? Will previously installed applications be able to launch again after they are closed? What will the user see when they try to install the application with the revoked certificate?

App Groups on macOS, 'Register App Groups' Code Signing Problems
So I just updated Xcode to 16.3 and updated a project to its recommended build settings which includes "Register App Groups". So I have an outside Mac App Store app that uses app groups. Here we have an action extension. I can't debug it, can't get it to run. Nothing useful in Xcode is displayed when I try... but it looks like a code signing issue when I run and have Console open. So I try to make a provisioning profile manually and set it...didn't work. I noticed now though in signing & capabilities the group id is in red...like it's invalid, or something? This was a "macOS styled" group without the "group." prefix. So am I supposed to switch it to have the group. prefix? It makes the red text go away (no warnings or anything about app groups here, just red text). So if I change it to group. prefix..does that make an entire new container?What happens on app update for installs that don't have group. prefix? Does the system transparently migrate the group? Or Am I supposed to migrate the entire group container to the identifier with group. prefix? Also how does this affect running on older version of macOS? If I go with the "group." prefix to make the red text go away,.. what happens on macOS 11.0? Got a little more than I bargained for here after midnight.

Notarization hangs forever
I've been trying to have an app I've built notarized by Apple. The processing hangs there for hours just waiting. I even tried with a tiny 1KB test file, it has been stuck for 25+ minutes, and I have 7 real submissions stuck for 24+ hours. Any Apple representative can help please? I need to publish and release my app asap.

Upload failed Validation Issue WKApplication or WKWatchKitApp is required
I added a watchkit extension to an existing app. I get this error when uploading to App Store Connect. Building the archive itself is fine: Prepared archive for uploading Upload failed error: Validation failed Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “Runner.app/Watch/watch_Watch_App.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project have the exact same issue when bundling. I added the flag manually in a additional plist fields entry with WKApplication=1 because my Info.Plist is generated and it didn't help. I wrote a custom Run Script Phase that added the flag and that didn't help as well. I need a reply from someone from Apple here. This needs to be fixed.

Mac App Packaging
Can someone please explain why Mac app packaging is so farcically convoluted? Windows app packaging can be picked up in an hour or so. But I've spent longer trying to fathom how to package the Mac version than I did building the app. And it's not done with me yet. Every single line of code requires a deep dive into a new, unrelated skillset. So, it’s sidebar after sidebar. Kafka’s ‘The Trial’ comes to mind. Why does it have to be like this?

App Store code signing show "Beta Profile"
I encountered code signing issue with Apple Distribution certificate for both iOS and MacCatalyst. The app crashes with "Beta Profile". I followed this instruction to manually re-sign my ipa to confirm that I use the Apple Distribution and the correct Provisioning Profile. https://gist.github.com/WDUK/4239548f76bd77b2c4b0 When I double click on the Apple Distribution certificate in KeyChain Access, it shows "Extension: Apple Mac App Signing (Development)" and "Extension: Apple Developer Certificate (Submission)" I have been stuck in this issue for more than a month. I really need help because I do not know how to proceed further. Thank you.

codesign error - No such file or directory
I'm having a problem with codesign for output from Pyinstaller The files are in ~/PycharmProjects/ALP_Document_Factory_II That folder contains the icon file, the entitlement file, and also contains a "dist" folder where Pyinstaller places the app file (ALP_Document_Factory_II.app) The generated app works and runs when I double click it. When I run codesign: codesign -s xxxxxxxx -f --entitlements entitlements.plist -o runtime dist/ALP_Document_Factory_II.app ("xxxxxxx" is where I place the hash of my credential) I get the following error message: No such file or directory Here is the Terminal copy... minus my Hash dickl45@Dicks-iMac3 ALP_Document_Factory_II % codesign -s xxxxxxxxxx -f --entitlements entitlements.plist -o runtime dist/ALP_Document_Factory_II.app dist/ALP_Document_Factory_II.app: No such file or directory Earlier I was able to use codesign and notarytool, but I must be doing something wrong that I can't see.

Cloud Signing via Developer ID doesn't seem to work with Admin API Keys
Hi, I'm having a really hard time figuring out why I cannot perform cloud signing via Developer ID with xcodebuild. I have a macOS application, which I can perfectly cloud sign the following way: Sign into Xcode with my Admin + Account Holder Apple ID. Delete my Developer ID Application certificate from Keychain Access. In Xcode, click Archive. When archived, click "Distribute App" in Xcode Organizer. The app is cloud signed. I prove this by extracting the certificate codesign --extract-certificates -- /path/to/app.app then locate the 1.2.840.113635.100.6.1.32 bit mentioned by Quinn in this post. I however do it by simply opening the certifiacte with Keychain Access, where I can investigate the content of the certificate, rather than use that tool he does. Then, I do the following to attempt to cloud sign via xcodebuild: Create an API Key for the whole team in Users and Access > Integrations > App Store Connect with the "Admin" role selected. Download the private key .p8 file to ~/Downloads. Sign out of my Apple ID in Xcode by removing the account in Settings > Accounts. Create an archive: xcodebuild archive -scheme "<redacted scheme name>" -archivePath ~/Downloads/archive.xcarchive -authenticationKeyIssuerID <redacted issuer id> -authenticationKeyID <redacted key id> -authenticationKeyPath ~/Downloads/AuthKey_<redacted key id>.p8 -allowProvisioningUpdates The archive is successfully created, with a new "Apple Development: Created via API (TEAM ID)" naming. Export the archive: xcodebuild -exportArchive -archivePath ~/Downloads/archive.xcarchive -authenticationKeyIssuerID <redacted issuer id> -authenticationKeyID <redacted key id> -authenticationKeyPath ~/Downloads/AuthKey_<redacted key id>.p8 -allowProvisioningUpdates -exportOptionsPlist ~/Downloads/exportOptions.plist -exportPath ~/Downloads which then fails: 2025-03-07 10:27:58.706 xcodebuild[2152:40704] [MT] IDEDistribution: -[IDEDistributionLogging _createLoggingBundleAtPath:]: Created bundle at path "/var/folders/tn/yy7ynz3d0yb4p3sd_5q_wl0h0000gn/T/<redacted app name> macOS_2025-03-07_10-27-58.706.xcdistributionlogs". error: exportArchive Cloud signing permission error error: exportArchive No signing certificate "Developer ID Application" found ** EXPORT FAILED ** Opening the distribution logs, I find this in the Provisioning Log: 2025-03-07 09:09:58 +0000 2025-03-07 09:09:58 +0000 IDEProvisioningRepair(<redacted app name>.app): 2025-03-07 09:09:58 +0000 IDEProvisioningRepair(<redacted app name>.app): Sending request 84E57539-BC1D-407A-8402-7BCE9F2FD100 to <https://appstoreconnect.apple.com/xcbuild/v1/certificates> for session DVTServicesTeamBasedSession <issuer: <redacted issuer id>; key identifier: <redacted key id>>.

Please contact your team's Account Holder or an Admin to give you access. If you need further assistance, contact Apple Developer Program Support at https://developer.apple.com/contact/." } ] } Which is really weird, since I am using an API key with Admin rights. If I create a new key, and use it only for this command, App Store Connect does show the "Last Used" date as today after running the command. I thought some time might need to pass, but the issue has been persisting since yesterday. What could be wrong here? I do have a managed Developer ID Application certificate showing in my account but I still can't retrieve it with an Admin right imbued API key.

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

Notarization stuck on "In Progress"
Hi there, I've developed a macOS app in Swift and SwiftUI. I'm planning to distribute the app outside of the App Store, so I'm currently getting it notarized. This is my first time notarizing an application. My application is signed correctly during the build / archive process, but whether I try to notarize the .app via Xcode's organizer or a .dmg via notarytool, it seems to get stuck. The status of Notarization attempts have been been stuck "In Progress", with the earliest attempt approaching 4 days. Below is the output of xcrun notary tool history Successfully received submission history. history -------------------------------------------------- createdDate: 2025-01-01T08:25:21.033Z id: be860d89-9edd-4330-9358-aa3766772041 name: Sidekick.zip status: In Progress -------------------------------------------------- createdDate: 2024-12-31T17:08:37.493Z id: 9cbd609e-d287-4217-afe3-362386159805 name: Sidekick-beta.dmg status: In Progress -------------------------------------------------- createdDate: 2024-12-31T15:35:11.609Z id: 3e22c207-e156-410d-a0d1-24a587bfdca6 name: Sidekick.zip status: In Progress I've been searching for similar issues on the developer forums, and while others have warned about long wait times for first-time notarization requests, I've never come across anyone else who had to wait 4 days.

Failed qualification checks ad-hoc profile
Hi, We have an app that is a default mail client, so it has this entry in its entitlements file: com.apple.developer.mail-client. This seems to create issues with ad-hoc distribution. We can distribute the app on App Store Connect without any issues and have been doing so for a while. We wanted to try using Xcode Cloud to manage our releases. The app export works fine for both App Store Distribution and Development Distribution. However, the ad-hoc distribution step fails. (We don't need ad-hoc distribution, but Xcode Cloud seems to prevent us from removing this step.) I tried building and releasing the app locally for ad-hoc distribution and encountered the same error as on Xcode Cloud. When Xcode tries to generate the profile, it outputs the following error: Provisioning profile "iOS Team Ad Hoc Provisioning Profile: com.infomaniak.mail" failed qualification checks: Profile doesn't support Default Mail App. Profile doesn't include the com.apple.developer.mail-client entitlement. Is it something broken with our config ? What are we missing ? Local error in Xcode Organizer: Remote error on Xcode cloud:
