Possible bug in Capability Requests tab
Hello, Recently our team requested the "Notification (NSE) filtering" capability. Our request was rejected but we sent a new request with a more detailed explanation of our need. However if we go check the status of the request in the Capability Requests tab the status is "No requests". We sent the new request yesterday. Is it even possible to request a capability after a rejected request? We really need the capability and the absence of it is blocking our progress.

"Provisioning profile does not allow this device" on Sequoia 15.2 VM
After upgrading the virtual machines used for building and testing our macOS application, it seems that something new in Sequoia is preventing virtual machines from running anything signed with a Mac Development certificate. At first glance the issue seems very similar to this thread, but it could be unrelated. We are using the tart toolset to build and run our VMs. People seem to be having related issues there with Sequoia in particular. I have added the VM's hardware UUID to the Devices list of our account. I have included that device in the devices list of our Mac Development provisioning profile. I have re-downloaded the profile, ensured that it is properly getting built into the app, and ensured that the hardware UUID of the VM matches the embedded provisioning profile: Virtual-Machine App.app/Contents % system_profiler SPHardwareDataType | grep UUID Hardware UUID: 0CAE034E-C837-53E6-BA67-3B2CC7AD3719 Virtual-Machine App.app/Contents % grep 0CAE034E-C837-53E6-BA67-3B2CC7AD3719 ../../App.app/Contents/embedded.provisionprofile Binary file ../../App.app/Contents/embedded.provisionprofile matches However, when I try to run the application, it fails, and while I have searched the system logs to find a more informative error message, the only thing I can find is that the profile doesn't match the device somehow: Virtual-Machine App.app/Contents % open ../../App.app The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x6000039440f0 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}} Virtual-Machine App.app/Contents % log show --info --debug --signpost --last 3m | grep -i embedded.provisionprofile 2025-01-21 16:33:32.369829+0000 0x65ba Error 0x0 2872 7 taskgated-helper: (ConfigurationProfiles) [com.apple.ManagedClient:ProvisioningProfiles] embedded provisioning profile not valid: file:///private/tmp/builds/app/.caches/Xcode/DerivedData/Build/Products/Debug/App.app/Contents/embedded.provisionprofile error: Error Domain=CPProfileManager Code=-212 "Provisioning profile does not allow this device." UserInfo={NSLocalizedDescription=Provisioning profile does not allow this device.} I don't understand why the provisioning profile wouldn't allow the device if the hardware UUID matches. I have also attempted to add the Provisioning UDID in the devices list instead, but the form rejects that value because it's a different format (the form specifically requests a hardware UUID for macOS development, and a provisioning UDID for everything else). If there is any debugging tool that lets me check a provisioning profile against the running hardware and print a more verbose reason for why it's not allowed on the device, please let me know. Otherwise I'd have to conclude that, since I haven't experienced this issue before on an earlier OS, it has something to do with virtual machines running macOS Sequoia. (The same Mac Development-signed application runs just fine on my MacBook Pro running 15.2, as well as the VM host, which is also running 15.2.) I have also tried resetting the VM's hardware UUID and adding that one to the devices list, to no effect. This is obviously seriously impacting our CI/CD pipelines to allow for proper UI testing of our application. If anyone is aware of any workarounds, I would love to hear them!

Can't publish to Testflight with Tap to Pay on iPhone entitlement despite it being granted
Hello, I went through the verification process to get the Tap to Pay on iPhone entitlement, and after a couple of corrections I was finally assured that I was granted the entitlement for production use. However, in App Store Connect, I can only see "Development" for "Provisioning Support" of the entitlement, and I'm not able to publish the app to Testflight because the profile doesn't support the entitlement (I'm using automatic code signing with XCode). Where is this going wrong? The Tap to Pay support assured me they granted the right entitlement and pointed me to the developer support. Thank you, Johannes

All Notarization Requests Stuck "In Progress" for Over 48 Hours
Hello, We are currently facing an issue with the Apple Notary Service that is completely blocking our production pipeline. For the past three days, every single submission has been stuck in the "In Progress" state indefinitely. Some submissions have been pending for over 48 hours, and none of them ever proceed to analysis. When checking the status via xcrun notarytool history, all entries show "In Progress". Attempting to retrieve logs with xcrun notarytool log always returns: Submission log is not yet available. This strongly suggests that the processing hasn't even started. This issue occurs consistently from my local machine (MacBook Air M3) and Our GitHub Actions CI workflow. Both environments are properly configured with Electron + Electron-Builder, and the app is correctly signed and uploaded each time. We have verified multiple times all credentials and code signing settings, no exceptions so far or problems in the pipeline. Here are a few stuck submission IDs: This is not a normal delay, it looks like a backend issue affecting our account or this specific App ID. Please escalate this case as soon as possible. We appreciate your urgent attention. Best

In-App Purchase Grayed Out & Provisioning Profile Error
Hello, I’m facing an issue with enabling In-App Purchases (IAP) for my iOS app, and it’s causing provisioning errors during the build process. Issue: • In Apple Developer Portal → Certificates, Identifiers & Profiles, the In-App Purchase capability is checked but grayed out, so I can’t modify it. • In Xcode, under Signing & Capabilities, I don’t see In-App Purchase listed. • When trying to build, I get the following error: Provisioning profile “BillionMines_Dev_Profile” doesn’t include the com.apple.developer.in-app-purchase entitlement. • Automatic signing in Xcode fails with: Xcode failed to provision this target. What I Have Tried: 1. Verified that my App ID is explicitly defined (not a wildcard ID). 2. Regenerated and downloaded a new Provisioning Profile, ensuring it matches my app. 3. Confirmed that In-App Purchase is enabled in App Store Connect under Features. 4. Cleaned the build folder and restarted Xcode. 5. Manually added com.apple.developer.in-app-purchase to my .entitlements file. Questions: • Why is the In-App Purchase option grayed out in Certificates, Identifiers & Profiles? • How can I ensure my provisioning profile includes the com.apple.developer.in-app-purchase entitlement? • Are there additional steps required to fully activate In-App Purchases? Any help would be greatly appreciated! Thanks in advance.

dlopen on development iPhone codesign issue
Hi, For the purposes of iteration speed in development builds, on an iPhone in development mode, I am attempting to use hot reloaded dylibs. The goal is that the app is rarely fully restarted and small code changes can be applied quickly, drastically reducing iteration speed. For this purpose I have a socket server on my Mac that sends changed dylibs to my app on my iPhone. This works great on Mac, however on iOS i am running into codesigning problems. I am using the following to codesign the dylib: codesign -f -s XXX --timestamp=none testlibrary-ios.dylib I am placing the downloaded dylib in this folder: const char* cachedirectoryPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0] UTF8String]; dlopen gives me the following error: dlopen(/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib, 0x000A): tried: '/usr/lib/system/introspection/testlibrary-ios.dylib' (no such file, not in dyld cache), '/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib' (code signature invalid in <78A101AD-D756-3526-8754-8B7F4925DE90> '/private/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib' (errno=1) sliceOffset=0x00000000, codeBlobOffset=0x0000C2E0, codeBlobSize=0x00004990), .... Is loading a dylib like this on iPhones in development mode possible? Any idea what is going wrong with codesigning or installing the dylib? (Obviously this code is never deployed in an app that goes on the AppStore)

Notarization takes almost a week
Hi everyone! I've send my .dmg file for notarization, it has been accepted on March 5. Since then there weren't any updates, it hasn't changed its status. What might be the problem?

Creating codesigned AppleScript apps
In the past it was relatively easy to download from the developer portal both the app signing and installer signing certs so that I could sign AppleScripts from Script Editor when exporting them and when building packages in Jamf Composer. I went to set that up today and it seems things have changed in the last few years since I've had to set this up. I've been unable to sort this out and would love some help. I'm looking for a tutorial on doing this that walks someone step-by-step through the process for obtaining the certs (yes, I have dev account) and setting them up in keychain and then making use of them. Thanks!

self-signed jre works in one macos account, but not another
Hi, I have a macOS Intel machine running Ventura 13.7.4. This machine is used as a build node for Jenkins to run a test for a USB device that has an HID interface. The test runner for this is Java's junit on Azul's Zulu JDK 8 for mac. I've added the com.apple.security.device entitlement to this JDK 8 bundle and signed using a self-signed certificate. This certificate is available in the system keychain at: keychain: "/Library/Keychains/System.keychain" version: 256 class: 0x80001000 On my personal account on this machine, I can run the test and it calls IOHIDDevicePlugin's open function and returns success: [junit] [debug] [hid.cpp:1457] HIDAccess::Open Success in open for cDeviceHandle: 0x6000006abb38 If I run the same test logged in as the Jenkins agent account, then open returns: [junit] [debug] [hid.cpp:1484] Could not open HID with handle: 0x600002a5c018, error (-1ffffd3f): (iokit/common) privilege violation I can see the certificate that signed the JDK bundle running the command: security find-certificate -c "java-rt-usb" -a -m The results are the same for both accounts. Is my setup expected to work? I.e. create a self-signed cert in one account with admin privileges, put the cert in the system keychain, sign an app bundle with a new usb entitlement using this cert, and then run that app in another account on the same machine. If it's expected to work, are there any more troubleshooting tools I can use? ioreg shows the same output for these devices under test in both accounts: $ ioreg -p IOUSB -w0 +-o CMSIS-DAP@14620000 <class AppleUSBDevice, id 0x1000026ae, registered, matched, active, busy 0 (1 ms), retain 17> +-o CMSIS-DAP@14630000 <class AppleUSBDevice, id 0x1000026d6, registered, matched, active, busy 0 (1 ms), retain 17>

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!

security find-identity -v -p codesigning 0 valid identities found
I am trying to resign a package using a script from Docebo. But I got an error when running the script error: The specified item could not be found in the keychain. So I ran security find-identity and I got a 0 Valid identity message. But I can see these certificates installed in my keychain and downloaded a brand new mobile provissioning profile. No dice... any ideas?

Checking DMG notarization. Rejected, but works fine
I have a misterous problem with checking DMG notarization. It fails: bash-3.2$ spctl -a -t open --context context:primary-signature -v MyApp.dmg MyApp: rejected source=no usable signature However this DMG installs fine on Big Sur 11.2.2, macOS allows to run this app, and checking of notarization for installed app was passed: bash-3.2$ spctl -a -v '/Applications/MyApp.app' /Applications/MyApp.app: accepted source=Notarized Developer ID I checked other downloaded apps (Intel or Universal). Some DMG files pass DMG notarization (for example, Audacity), and some fails (PerfectTablePlan). Why? For my app (Universal) I use the following code to codesign and notarize: codesign --timestamp --options runtime --force --deep -s "Developer ID Application: MYCOMPANY" "My.app" // Creating DMG with EULA license xcrun altool --notarize-app --primary-bundle-id MyApp -u "my@email.com" -p "abc123" --file MyApp.dmg xcrun stapler staple MyApp.dmg

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?

No iOS signing identities match the specified provisioning profile
Hello, I get this message when building from a .net maui app. I think I followed all the steps. I've downloaded my provisioning profile from developer.apple.com and my instructions (you tube) said to double click it and XCode will open. It does that but I don't see where the provisioning profile goes in xCode. I followed another link which told me to delete everything in /Users/username/Library/MobileDevice/Provisioning Profiles and after doing that I don't see any files reappearing when I click the provisioning profile from finder. Did I mess myself up following internet articles again? I'm running XCode Version 16.2 (16C5032a) under accounts I can see my appleid linked but I don't see the provisioing profile I loaded. Sorry very new at Mac development (and kinda cheating using Maui) Save me apple gods, Steven

Codesign Error When Publishing iOS MAUI App in Visual Studio Code
I am experiencing an issue when publishing my .NET MAUI application for iOS using Visual Studio Code. During the publishing process, I encountered a codesign error. Hope someone can help me.

MacOS crash, UnityPlayer.dylib
I’ve been having problems with MacOS builds. I’m making a release Appstore build and uploading it to Testflight. However when running it instantly crashes, and report screen shows the following: Current flow: I sign all files in PlugIns/ (we have a number of .bundle), and I’ve tried combinations of signing with/without --entitlements, as well as with/without --deep. After this I sign Frameworks/GameAssembly.dylib and Frameworks/UnityPlayer.dylib. Again, I’ve tried combinations of with/without --entitlements and --deep, also not signing them at all. After signing PlugIns and frameworks, I sign the .app, also tried this with/without --deep (always with --entitlements). Finally I make a .pkg and upload to Testflight. It’s not the game, as I can make an enterprise version that runs fine. We have some restricted entitlements, such as Apple Arcade. Building from an M1 mac, and architecture is Universal (Intel + ARM). Unity documentation says to use --deep, but Apple documentation highly recommend against it. So basically, my question is, how and in what order should I sign the files? Much obliged!
