My sandboxed macOS app requires the user to grant permission under Privacy & Security / Accessibility in order to support extra functionality. If no permission is granted the app can still be used albeit with very basic functionality. In order to allow the user NOT to have to immediately decide whether to grant this permission when first launching the app, a dialog allows them to say “I’ll do it later”. As such, the app uses a timer with a one second interval to ask the system if permission has been granted and if so, implements the extra functionality. By the way, I would rather have used a notification instead of a timer, but there does not seem to be one. // Schedule a timer to periodically check accessibility status accessibilityTimer = Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(checkAccessibilityStatus), userInfo: nil, repeats: true) func isAccessibilityEnabled() -> Bool { let accessibilityEnabled = AXIsProcessTrusted() return accessibilityEnabled } @objc func checkAccessibilityStatus() { if isAccessibilityEnabled() { print("Accessibility is enabled.") accessibilityTimer?.invalidate() if gEventTap == nil { tapper()//as003 gTypeIt4MeMenu?.item(at: kPauseResumeItem)?.title = "Pause" gStatusItem?.button!.image = NSImage(named: "menubar_icon_16x16") NotificationCenter.default.post(name: NSNotification.Name(rawValue: "showGreenTick"), object: nil) } } else { print("Accessibility is disabled.") } } My problem is that when I build the app with my development certificate, it runs as expected. However, when I upload it to TextFlight and download from there, it no longer “notices” when I grant it permission.

Hi team We are facing following message "A timestamp was expected but was not found" during codesign for following .pkg file and it cause Jenkins NB process failed. We are facing this issue for last 3 days as it was working on last 18th January. Kindly let us know how to fix this problem. Rgds

Both the codesign tool and Xcode allow you to sign code with a hardware-based code-signing identity. However, setting that up can be a bit of a challenge. Recently a developer open a DTS tech support incident requesting help with this, and so I thought I’d post my instructions here for the benefit of all. If you have any questions or comments about this, please start a new thread, tagging it with Code Signing so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Signing code with a hardware-based code-signing identity Both the codesign tool and Xcode allow you to sign code with a hardware-based code-signing identity. This post explains how to set that up. I used macOS 14.2.1 with Xcode 15.2. For my hardware-based key I used a YubiKey 5 NFC that I reset to its defaults. I installed YubiKey Manager 1.2.5. IMPORTANT While I used a YubiKey, the code signing parts of this process should work with any token that has a functioning CryptoTokenKit driver. In the case of the YubiKey, it presents a PIV interface and thus it’s supported by macOS’s built-in PIV CryptoTokenKit driver. In this example I created an Apple Development certificate because those are dime a dozen. This process should work with any other type of code-signing certificate. Indeed, it make sense to store your most precious keys in a hardware token, including your Developer ID keys. For more on that topic, see The Care and Feeding of Developer ID. Generate a certificate signing request To generate a certificate signing request (CSR): Connect the YubiKey via USB. Dismiss any system alerts: If the “Allow this accessory to connect?” alert comes up, click Allow. If the Keyboard Setup Assistant comes up, quit that. If the ctkbind notification comes up, dismiss that. Coded signing does not require that you bind your login account to your hardware token. Launch YubiKey Manager. Choose Applications > PIV. Click Configure Certificates. Select Digital Signature (slot 9c). In the past I’ve run into situations where signing fails if you don’t use this slot, although I haven’t tested that in this particular case. Click Generate. Select Certificate Signing Request (CSR) and click Next. Select the RSA2048 algorithm and click Next. Enter a subject and click Next. The value you use here doesn’t matter because Apple ignores pretty much everything in the CSR except the public key. Click Generate. Choose a save location and name. Don’t include a file name extension. When prompted for the management key, enter that and click OK. When prompted for the PIN, enter that and click OK. The app will generate a .csr file at your chosen location. Quit YubiKey Manager. Note Apple typically uses the .certSigningRequest extension for CSRs, but this process works just fine with the .csr extension used by YubiKey Manager. Generate a certificate from your CSR To generate a certificate from that CSR: In Safari, go to Developer > Account and log in. If you’re a member of multiple teams, make sure you have the correct one selected at the top right. Click Certificates. Click the add (+) button to create a new certificate. Select Apple Development and click Continue. Click Choose File, select your CSR file, and click Upload. Click Continue to generate your certificate. That takes you to the Download Your Certificate page. Click Download. In Terminal, calculate a SHA-1 hash of your .cer file. % shasum "development.cer" 840f40ef6b10bedfb2315ac49e07f7e6508a1680 development.cer Import the certificate to form a code-signing identity To import this certificate into your YubiKey: Convert the certificate to PEM form: % openssl x509 -in "development.cer" -inform der -out "development.pem" Launch YubiKey Manager. Choose Applications > PIV. Click Configure Certificates. Select Digital Signature (slot 9c). Click Import. In the file dialog, select the PEM and click Import. When prompted for the management key, enter that and click OK. The UI updates to show the certificate issuer (Apple Worldwide Developer Relations Certificate Authority) and subject (Apple Development: UUU, where UUU identifies you). Quit YubiKey Manager. Unplug the YubiKey and then plug it back in. Sign a test program Before digging into Xcode, check that you can sign code with the codesign tool: Create a small program to test with. In my case I decided to re-sign the built-in true command-line tool: % cp "/usr/bin/true" "MyTool" % codesign -s - -f "MyTool" Run codesign to sign your program, passing in the SHA-1 hash of the certificate you imported into the YubiKey: % codesign -s 840f40ef6b10bedfb2315ac49e07f7e6508a1680 -f "MyTool" When prompted for the PIN, enter that and click OK. The codesign invocation completes like so: % codesign -s 840f40ef6b10bedfb2315ac49e07f7e6508a1680 -f "MyTool" MyTool: replacing existing signature Sign from Xcode To sign from Xcode: Open your project in Xcode. In my case I created a new project by choosing File > New then selecting macOS > Command Line tool. In Signing & Capabilities for the tool target, turn off “Automatically manage signing”. In Build Settings, find the Code Signing Identity build setting, choose Other, and then enter the SHA-1 hash of your certificate. Choose Product > Build. When prompted for the PIN, enter that and click OK. The build then completes. IMPORTANT This requires Xcode 13 or later. Earlier versions of Xcode only work with file-based code-signing identities.

Hello I jump on my mac every 3-4 months to release new version of my apps. Process usually is "ok" some cmake/compile issues as 99% of dev is done on windows but other than that its all good. But now I'm stuck. My app can run locally/start etc just fine, but clients are panicking because they can't run them. They have undefined developer warning. I don't understand this. Its notarised and been working for 2 years. What am I doing wrong ?! How can I test it ? I tried creating new user-profile on my mac, but there is no issue, app starts. Do I need to buy ANOTHER mac to test my apps before release ?! Can any1 help how to debug this issue? I'm lost, I used finder-compress myapp.app & send it via slack to client to get him quickly going but that does not help either. - I though it was zip stripping down data or something. Anyway, very frustrated here, and lost. Can any1 help? hint? Is this good resource to check against? https://developer.apple.com/library/archive/documentation/Security/Conceptual/CodeSigningGuide/Procedures/Procedures.html I've run spctl --assess --type execute myApp and I'm getting rejected (bundle format is ambiguous (could be app or framework)) But then why does it notarize/sign/etc with no errors ?! I'm so lost :- (((( Any help would be greatly appreciated I've attached app content > Ok I've tested my older releases, they all have the same issue but they all work on client system. I'm so lost :- (((

I'm working on an app using entitlements. The entitlements are setup in its code signature and they are also applied in the corresponding provisioning profile. I embed said provisioning profile in the app, but when I launch the binary it gets rejected by taskgated-helper (as seen in console.app it says "profile not found"). However, if I install the same embedded provision profile it will work! So I can only assume taskgated-helper is not looking in the Contents/embedded.provisionprofile file when I try to run the binary? I can only imagine that the issue revolves around the binary not being the main bundle binary in the application, as that one works just fine without installing the profile. I would simply install the profile to fix the issue, but it brings other problems when trying to install the application in a headless environment (as opening the profile to install in system settings requires user interaction). Any ideas?

Hi, I've ran into an issue which only seems to affect one of my macs. It's currently running 14.2.1 but I first saw this issue in 13.6. If I download the macOS Sonoma 14.2.1 installer (via App store) onto this particular machine, it will never execute the installer. It always reports that the installer is "damaged". Of course I did reasearch this online and you get the usual unhelpful posts which just say "re download it" and of course, I wouldn't be posting here had I not tried that. This happens with any macOS installer I download using the softwareupdate --fetch-full-installer utility as well. The thing is, if I copy this .app to another (identical as far as I can tell) Mac - it will work. So far this also seems limited to macOS installers - other third party apps are fine. I'm convinced this is related to trusted execution and something has gone wrong in the environment. I've been looking at my router logs to see if any connections may have been blocked (I'm using OPNsense) and also looking to see what connections are being made via Little Snitch and so far it looks fine. Again, other machines on the network can run these just fine. I've read through eskimo's excellent guide here: https://forums.developer.apple.com/forums/thread/706442 but I was wondering if anyone can give me some pointers to narrow this down further. As it stands, I can't trust this machine for app development if I can't even get the official Apple installers to run sucessfully.

I am looking for any help regarding an errSecInternalComponent error I am seeing when trying to archive my iOS app via my CI process. Specifically, this CI process is a GitHub Action running on a self-hosted M2 Pro Mini machine to which we have Screen Share access. I have followed the very helpful seminal post and have confirmed that I can run the necessary command in the local terminal via Screen Share, and I don't get any Keychain Access dialogs to pop up. When I try to run the same command via an SSH terminal from my local machine on that same machine, I get the following error: /Users/{username}/Library/Developer/Xcode/DerivedData/{projectID}/Build/Intermediates.noindex/ArchiveIntermediates/{projectname}/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/{some name}NotificationServiceExtension.appex: errSecInternalComponent I only get the error for that one service extension target. The project is only a couple years old, created with Xcode 14 or maybe 13. The signing has always been managed automatically with the provisioning profiles for all our targets being managed by Xcode. Thanks in advance for any advice or suggestions as to what I may be missing or how to address this problem. I am more than happy to provide any more information I can to diagnose and solve the issue.

Two days ago everything was working fine. Then I decided to step on with the OneSignal Sdk and the problems starts to come. Now I have two big problem but I want to go with order and begin from the first and maybe the second will follow. When I try the app on emulator, it builds fine but stopped immediately with The parent bundle has the same identifier (com.domain.bundlename) as sub-bundle at /Users/myname/Library/Developer/CoreSimulator/Devices/F2D73A5F-1B86-4D2D-9989-518387D0FB24/data/Library/Caches/com.apple.mobile.installd.staging/temp.O4MORK/extracted/Runner.app/Frameworks/App.framework (com.domain.bundlename is for obscuring the real ones) Then I tried creating a new emulator device, but I got the same error. No clues on my internet search.

Is setting "Enable App Sandbox : Yes" required for distributing an app to the App Store? I'm building my first app, a game, and can only test on my physical device with the Sandbox set to No. I can run it on the emulators with Sandboxing enabled. I'm still using the free developer account and will be enrolling in the paid account once 2024 arrives.

We have started creating third-party applications and for that we required to apple certificate and initially created multiple certificate (application and installer), later on realises that one can be enough to approve multiple application. Now we are not seeing any option to remove or revoke the certificates so that we can create new certificate. Support team also not able to help on this. What should we do to create new certificate?

Hi, after many hours looking for a solution I hope to find one here :) I am creating an ios application using flutter. Since updating my macbook to MacOs Sonoma it is impossible for me to launch an archive of the application on Xcode (the error below is displayed). By searching I thought I understood that it could come from Icloud but even if I put my App in the Application folder, I got this error. I can launch my application on Simulator but not on a physical phone either. error: Target release_unpack_ios failed: Exception: Failed to codesign /Users/etiennemary/Library/Developer/Xcode/DerivedData/Runner-hcgaysxersoeaugykishvsewlgps/Build/Intermediates.noindex/ArchiveIntermediates/Runner/BuildProductsPath/Release-iphoneos/Flutter.framework/Flutter with identity ...... /Users/etiennemary/Library/Developer/Xcode/DerivedData/Runner-hcgaysxersoeaugykishvsewlgps/Build/Intermediates.noindex/ArchiveIntermediates/Runner/BuildProductsPath/Release-iphoneos/Flutter.framework/Flutter: replacing existing signature Warning: unable to build chain to self-signed root for signer "Apple Development: Etienne Mary (. )" /Users/etiennemary/Library/Developer/Xcode/DerivedData/Runner-hcgaysxersoeaugykishvsewlgps/Build/Intermediates.noindex/ArchiveIntermediates/Runner/BuildProductsPath/Release-iphoneos/Flutter.framework/Flutter: errSecInternalComponent Failed to package /Applications/aa/evento.

I want to distribute my app with my developer ID. This works fine in a dmg or zip container if I download it on another Mac by FTP. But if I download it by HTTPS macOS brings a Popup: “Rocrail.app” is damaged and can’t be opened. You should move it to the Bin. I don't understand the diff between FTP and HTTPS download... How can I fix this?

Searching for insight on the best and most compliant way to essentially merge two apps. They have the same functionality but one is much more advanced than the other, although the legacy app has a higher user count. Instead of letting both run, we want to push the legacy app an update with the code from the new app and ultimately kill the newer one. What is the best way to do this? Is it allowed to simply push the source code from new app to legacy and update the identifier? We do not wan't to break any app store rules and want to limit the potential of losing users by forcing them to download a new app.

I’m trying to implement XPC Rendezvous like Quinn described in many awesome posts on here but I’m now at a stuck point were I just have no idea. I want to communicate with a Safari extension via XPC and also a helper application which led me to XPC Rendezvous (https://developer.apple.com/forums/thread/715338) because a XPC Service in the Extension is scoped to the container. I then made a Command Line Target and added it like its described here (https://developer.apple.com/documentation/xcode/embedding-a-helper-tool-in-a-sandboxed-app ) and also took the xpc test code and inspiration to set up my launch agent from here (https://developer.apple.com/documentation/servicemanagement/updating_your_app_package_installer_to_use_the_new_service_management_api). This command line tool should do the management for the XPC connections because it’s not in the sandboxed container. The tool sets up the xpc connection like in the sample code directly and not in a XPC Service added via a Target template. It exposes the Mach Service. And that looks like its building fine after some fighting but the service just wont start - I saw it trying in console and after running it in Xcode and finally finding the crash report - it brought me there (https://developer.apple.com/forums/thread/706390) I have Process is not in an inherited sandbox. - and thinking about it, it makes sense because I first thought its just because it ran through Xcode, but its crashing this way also as a LaunchAgent. I mean it does make sense - there is nothing to inherit because it’s spawned by launchd - and that’s what I want isn’t it - to make the Rendezvous? Okay I thought now removing com.apple.security.inherit brings it in its own Sandbox (its needs sandboxing) but this also crashes the process because of the sandbox. Also after adding it to the App Group. What am I missing here or what do I want to accomplish? Do I want to inherit the sandbox? I guess not the helper should have its own. The only difference I see in comparison to SMAppServiceSampleCode is it moves the product in Copy Bundle Resources, and I have a Copy Files Phase with Destination: Executables (Like the other sample code said - and that’s looks “more correct” - and well SMAppServiceSampleCode isn’t sandboxed. I then tried making a new Command Line Target and just added App Sandbox Capability and tried to run this fresh one - and that also crashes. This makes me think I’m just ****** somewhere but I have read now everything I could find. I’m happy to provide any Code or crash logs but I dont know what part is really relevant here, It looks like the LaunchAgent gets installed correctly and wants to run but the sandbox is preventing me. The Bundle Identifier and XPC device name of the helper starts with my teamID (I got that from here https://developer.apple.com/forums/thread/703702) What could I be doing wrong? Thanks a lot!

Have been using a Mac for about a month, but am a 48-year engineer. Too many operating systems to list. Have my cross-platform self-contained Java application looking great on macOS with all the cool Mac conventions and a DMG "installer". Am attempting to get the existing self-updater working for macOS. It has conditional logic based on the operating system. But I'm stuck ... this is on a Macbook Pro 13" Retina Late 2013 2.8Ghz running macOS Big Sur 11.7.10 (fully updated). Deliberately supporting older hardware due to the nature of the application. The Process in Short Main program downloads updater program into a system temp directory Mounts updater DMG image with -mountroot in that directory Executes updater .app Exits Updater program downloads new Main program Mounts new program DMG image in the system temp directory The DMG image is the same one used for initial installations Makes back-ups of the Java and Plugins directories of existing program Copies the new Java and Plugins directories to existing Main program locations Umounts new program DMG image Either deletes back-up directories or restores them based on success or failure Restarts Main program .app Exits Main program receives special argument indicating success or failure of update Unmounts updater DMG image Displays appropriate dialog Issues The problems encountered are the mounting and unmounting of the DMG images executing hdiutil with Java Runtime.getRuntime().exec(). All mounts and unmounts have 1.5 sec. time-delayed retries for 3 attempts The initial download, mount, and execution of the updater works The mounting of the downloaded update DMG fails Running the command by hand works When the Main program is restarted the unmount of the updater DMG fails Running the command by hand works Also - these are unsigned images at this point. Have been unsure whether I would support macOS. But this is the last stumbling block. Questions Odd point - the initial download, mount and execution of the updater works Is this all because the DMG images are not signed (yet), so hdiutil is failing? Or is there something basic that I'm missing? Thank You For taking your time to read this. Any pointers would be appreciated.

This seems to work fine for the application itself (otherwise it wouldnt even try to load the dylib). What is going on ?

For a unit test, we are building a (non-bundled) test executable with the ENABLE_HARDENED_RUNTIME build setting enabled (set to "YES"), which eventually causes codesign to be run with the "--option runtime" setting. The resulting binary has the "hardening" bit (0x1000) set in the code signature and there are no exceptions per entitlements. In our unit test, we launch the test executable, obtain a SecCodeRef to the (dynamic) code using SecCodeCopyGuestWithAttributes() and inspect the flags in the signing information. We expect both kSecCodeStatusHard and kSecCodeStatusKill to be set for this code. When building and testing locally, this is always the case. When building and testing in our build pipeline, this is mostly the case, but every now and then, the test fails, because both "hard" and "kill" flags are missing from the signing information. It is my understanding that the "runtime" option (or the "hardening" bit in the signature) causes those two flags to be set when the code executes - is this incorrect or not guaranteed? If OTOH this is a correct understanding I would also assume that those flags are being set before the executable enters its main() function? Any explanation why we sometimes don't see those flags in the SecCodeRef for the guest code?

I created an application and initially I wasn't going to use it to send notifications, but then I realised that I needed to. So quite naturally, I changed the settings in "Certificates, Identifiers & Profiles". I activated : Communication Notifications Time Sensitive Notifications But not: Push Notifications Because it's a local application. However, when I transfer a new build to TestFlight, the notification settings are not present in "Settings" on my iPhone: Same thing, in the notifications settings, it doesn't show up :/. So my question is this: How can I get my notification settings to be "activated", knowing that they weren't originally authorised in my "Certificates, Identifiers & Profiles" settings?

Hi, Do we need a new Certificate, a new Identifier and a new Profile for each app that we want to create? Thanks, Best, Steeve

I am unable to run any Xcode projects - new or old. I think I messed up my certificates or profiles as I kept deleting and adding new versions but I have no idea how to fix this. Any help would be greatly appreciated.
