Suddenly receiving "Attempted to install a Beta profile without the proper entitlement" on a Flutter-based app
Hello! I'm suddenly having some difficulty debugging a Flutter-based app. When I run an app from VS Code, it launches Xcode and builds & installs the app on an iPhone running 18.1. However, once the app is installed on the phone, it disappears and in Xcode, a dialog appears with: Failed to install embedded profile for : 0xe800801f (Attempted to install a Beta profile without the proper entitlement.) However, when I look at the provisioning profile being used, it seems to have the correct entitlement: I've also tried enabling automatic signing (instead of the current manual signing using match), as well as generating an adhoc profile and re-adding the device UDID in developers.apple.com. None of these have worked. This issue appeared within the past day or so and was working fine yesterday with no code changes, so I've been stumped. All my certs are relatively new and were issued within the past few months. I've tried regenerating the provisioning profiles using match, but this gives the same thing. What's odd is that I can run the build and upload to testflight, then download and install the app just fine through there. But this obviously makes debugging an issue.

Handling Permissions After Transferring macOS App to a New Developer ID
I have a macOS application that was previously distributed under my personal Apple Developer account using a Developer ID certificate. We’ve recently transitioned distribution to our company’s Apple Developer account. The app’s bundle identifier has been successfully transferred, and I’ve signed a new build of the app using the company’s Developer ID certificate. The app installs and runs correctly under the new signature. However, I’ve encountered a problem: the app is no longer able to access previously granted permissions (e.g., Screen Recording, System Audio Recording, and Input Monitoring). Furthermore, it cannot re-prompt for these permissions because they appear as already granted in System Settings. From what I understand, this issue is due to the change in the code signing identity. Specifically, the designated requirements used by macOS to identify an app have changed, so the system no longer associates the new version of the app with the previously granted permissions (as outlined in Apple's Technical Note TN3127). The only workaround I’ve found so far is to manually reset the app's permissions using Terminal commands (e.g., tccutil reset), but this is not something we can reasonably ask end users to do. Question: Is there a recommended or supported approach to either preserve permissions when changing Developer ID identities, or programmatically trigger a permissions reset for existing users? We're looking for a seamless solution that doesn't degrade user experience.

Unable to install profiles on device and sign apps
I have tried again and again to generate and install the .mobileprovision on my device for testing apps following the exact instructions. I cannot get this to work. When I tap the .mobileprovision on the device I get the error "Profile Error - This profile cannot be installed." In Xcode in the console as I try to install the profile, this is what it shows: `profiled (ManagedConfiguration) Desc : Invalid Profile US Desc: Invalid Profile Domain : MCProfileErrorDomain Code : 1000 Type : MCFatalError and then profiled Desc : Invalid Profile Sugg : Invalid Profile US Desc: Invalid Profile US Sugg: Invalid Profile Domain : MCInstallationErrorDomain Code : 4000 Type : MCFatalError ...Underlying error: NSError: Desc : Invalid Profile US Desc: Invalid Profile Domain : MCProfileErrorDomain Code : 1000 Type : MCFatalError I have been at this for days and cannot get it to work. Any help would be appreciated

We are developing an application for MAC machine using .NET. After developing and signing the package in notarization process was failed with the error in the attached file. Then we have created the simple Xamarin.MAC to check whether able to notarize it . But with the simple project also we have faced the same error. Provide us the solution to fix these issues We have tried to codesiginin the app to resolve the notarization error, but while code signing the below error was thrown "unable to build chain to self-signed root for signer "Developer ID Application" (not mentioning the certificate id) SFSecure.app: errSecInternalComponent" Notarization-error

How can I export the "Notary Profile" used by notarytool for CI/CD
Once I have built my macOS .app and signed it I run notarytool using this simple shell script: #!/bin/sh ditto -c -k --keepParent "$1.app" "$1.zip" xcrun notarytool submit "$1.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple $1.app rm -f $1.zip How can I export that "keychain-profile" (notary profile) so I can use it in CI/CD actions? Clearly I don't wish to expose the full invocation of xcrun notarytool store-credentials.

SecTrustSettingsSetTrustSettings Fails on macOS 14.7.5 (ARM EC2) – "Authorization was denied since no user interaction was possible"
Hello Apple Developer Support, We are experiencing an issue when programmatically installing a trusted root certificate on EC2 macOS instances (ARM-based), running the latest version of macOS 14.7.5 (Build 23H527). We are using the following command as part of our automated setup process: sudo security authorizationdb write com.apple.trust-settings.admin allow sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain "$CERT_NAME" sudo security authorizationdb remove com.apple.trust-settings.admin This fails with the following message: SecTrustSettingsSetTrustSettings: The authorization was denied since no user interaction was possible In the past, as sugested in other posts (https://developer.apple.com/forums/thread/671582) we were able to bypass this issue by running: sudo security authorizationdb write com.apple.trust-settings.admin allow This worked successfully in prior versions, including earlier 14.x releases, and continues to work on Intel-based macOS instances. However, in macOS 14.7.5 (on ARM), this approach no longer works. We suspect this may be due to a change in how System Integrity Protection (SIP) is enforced, especially on EC2 ARM. Questions: Has Apple introduced any changes in macOS 14.7.5 that prevent modifying trust settings via security CLI on headless or non-interactive sessions? Is there an approved or documented way to install system-level trusted certificates programmatically on macOS 14.7.5 (ARM)? Are there alternatives for setting trustRoot certs in non-GUI environments, such as virtualized or cloud-hosted macOS instances? As further information we were thinking to use MDM Profiles but looks like it is also blocked Thanks

keychain and codesigning local dev
Trying to play around with Secure Enclave Protected keychain operations in a Tauri-based MacOS app and running into issues. After much digging and trial and error, here is my understanding and where I'm at: To access these keychain related APIs, the app must be codesigned, and have the following entitlements: <key>com.apple.application-identifier</key> <string>XXXXXXXXXX.com.myorg.myapp</string> <key>com.apple.developer.team-identifier</key> <string>XXXXXXXXXX</string> <key>keychain-access-groups</key> <array> <string>XXXXXXXXXX.*</string> </array> Currently using a Development cert, generated from Xcode, not a paid account I had to install the intermediate cert from https://www.apple.com/certificateauthority/ XXXXXXXXXX is the "Team ID", which can be found on my Development cert under Details > "Organizational Unit" If I build the app and run it (without signing) I get code 34018 If I sign the app and try to run it, I am no longer able to boot it, with error: The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x12a60a130 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}} Not quite sure what is missing - any help is much appreciated.

Code Signing Python Libraries
I am trying to code sign an application which relies on many python libraries to run. For background knowledge, the .app was created with a —onefile command on Visual Studio. I code signed my application itself using codesign --deep --force --verify --timestamp --sign "Developer ID Application: Issey Yohannes (GL5BCCW69X)" /Users/isseyyohannes/Desktop/Automated\ ALGORA.app However, when I try to run the application the error shows in terminal as follows [PYI-16345:ERROR] Failed to load Python shared library '/var/folders/g9/2zbc7y_97xxbq7bnc301nnyc0000gn/T/_MEI6keRcA/Python': dlopen: dlopen(/var/folders/g9/2zbc7y_97xxbq7bnc301nnyc0000gn/T/_MEI6keRcA/Python, 10): no suitable image found.

Any insight is much appreciated.

Error 65 upon stapling - cannot reset trust settings
Hi, I'm getting error 65 upon stapling and I am suspecting that non-default trust settings may be the reason as outlined here: Unfortunately whatever I do, I can't seem to reset the trust settings to their default values (removing the blue/white "+"), I'm not being asked for credentials upon closing the certificate window. I have also tried to unlock the System Roots key chain, to no avail. Also, when running security dump-trust-settings -d I get Number of trust settings : 0 for all certificates. Any ideas as to what I may be doing wrong? Is there any other setting that may be involved? Thanks!

Developer ID Certificate (How to replace damaged certificate?)
How do I replace an Apple Developer ID Certificate that indicates it is not trusted? When I look at my Certificate Expiring 02-20-2025, I see a valid status displayed. (See annotation #1.) However, when I look at my Apple Developer ID Certificate renewal, I see the words not trusted. (See annotation #2.) I downloaded the renewal certificate and double double-clicked the downloaded item to place it in my KeyChain. This certificate period is from 01-21-2025 to 01-22-2030. QUESTIONS Why does the renewal certificate say "certificate is not trusted"? (Its period is 01-21-2025 to 01-22-2030. Today is 01-27-2025.) How did the renewal certificate get damaged? What must I do to get the damaged certificate replaced with a valid one?

Code-signing and Notarization Accepted, but Stapler Fails with Error 65
Hello Apple Developer Community, I’m encountering an issue where my macOS app (signed with a valid ‘Developer ID Application’ certificate and accepted by Apple’s notary service) fails when I attempt to staple the notarization ticket. The Apple notary service reports ‘Accepted’ each time, but xcrun stapler staple always returns Error 65, with the local check (spctl -a -vvv) showing ‘Unnotarized Developer ID.’ Here are some key points: Certificate: I have a valid ‘Developer ID Application’ certificate (unexpired) in my login and system keychains, with Apple’s intermediate certificates also installed and set to System Defaults or Always Trust. Notarization: Regardless of whether I submit a .zip of the .app or the final .dmg for notarization, notarytool reports ‘Accepted.’ Stapling: xcrun stapler staple (or notarytool staple) on the exact file I uploaded fails with Error 65, claiming it can’t validate the downloaded ticket. Environment Checks: Checked for duplicate or outdated certificates—only one Developer ID remains. Repeated on multiple code-signed builds (both .app and .dmg) with the same result. Manually tested code-signing the .app with entitlements (for the hardened runtime) and then signing the .dmg without entitlements. Logs: The relevant excerpt from stapler indicates “Could not validate ticket for [app]. The staple and validate action failed! Error 65,” even though Apple’s notary service claims success. Could you please advise any additional troubleshooting steps or possible causes for local validation failure after a successful notarization? I’ve already ensured the environment is up to date with valid intermediates, only one Developer ID certificate. Any insight on diagnosing ticket mismatch or known tool bugs with Error 65 would be appreciated. Thank you!

Apple Certification Expired
Hello everyone. I have a simple doubt, I receive an email informing that the Apple Distribution certificate will expire. I create one new in the Developer portal with one year duration. My doubt is, I need to do something more like open again the app in Xcode, insert new certificate and build it again, send to apple and everything? Or just creating this certification is enough? Is possible to increase this certification time or auto renew? Thank you!!!

Local DriverKit development blocked by provisioning profile requirement
Hi, I am working on a personal HIDDriverKit project. The documentation suggests that you do not need the entitlements from Apple to do local development - that all you need to do is turn of SIP, enable developer mode, and turn signing to "Sign to Run Locally". However, I have followed all of these steps, and am still running into the error that to build, I need to have a provisioning profile with the DriverKit (development) feature (MacOS 15.2 Xcode 16.2). Am I missing something here regarding the steps for local development? Does one need to request a development version of the entitlements even for local development? Do I need a paid developer account to do this? Thank-you in advance.

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)
