An open-source app that I bundle for macOS needs to use the disable-library-validation entitlement. In spite of TN3125: Inside Code Signing: Provisioning Profiles | Apple Developer Documentation#Entitlements-on-macOS claiming that hardened runtime entitlements don't need provisioning profiles and the app successfully notarizing, trying to run the app fails with the error "Disallowing because no eligible provisioning profiles found". So I created a provisioning profile, but when creating the App ID the only selection that seemed relevant was Hardened Runtime. That turns out not to include disable-library-validation so now launching fails with "Unsatisfied entitlements: >com.apple.security.cs.disable-library-validation" What's the right capability?

I want to export Mac OS application out side App Store and I need to have Developer Id installer certificate to do the same. When I go to certificate section in developer portal - I only see option of Mac App Distribution Mac Installer Distribution Developer ID Application Does anyone know where I can check the Developer ID installer part. Developer ID application doesn't work for signing the app manually.

Hi guys, New to publishing apps on Apple Store. I encounter some notarization error before and resolved it in this post. By solving the previous issue, I updated the Trust setting from "Always Trust" to "Use System Defaults" for Apple certificates. The codesign and notarization no longer give me any problem. But now, I encountered another issue. When I ran the .app on my local Macbook, it now gives me "zsh: trace trap" error. Dive a little further and check the crash report, I found the some details as following. Process: my_app [30652] Path: /Users/USER/my_app_path Identifier: my_app Version: 0.0.0 (???)

We have an app which is hybrid using React Native and Native features. We released our app recently which showed issues related to missing packages/corrupt package but xCode didn't gave any error and we were able to Archive and submit app successfully.

Xcode automatic signing consistently fails for the macOS target when adding the App Groups capability, even though the Developer Portal is correctly configured. Error: Provisioning profile “Mac Team Provisioning Profile: com.example.testapp.mobile” doesn’t support the App Groups capability. Setup: • Bundle ID: com.example.testapp.mobile • App Group: $(TeamIdentifierPrefix)group.com.example.testapp.mobile Troubleshooting Steps Tried (None Helped): • Changed bundle identifiers and deleted/recreated them in the Developer Portal • Deleted and recreated App Groups • Removed and re-added the developer account in Xcode • Deleted all provisioning profiles from the system • Cleared Derived Data and Xcode caches • Even tried on a clean macOS system This setup used to work previously. The issue seems to have started after the Apple Developer account was renewed.

I submitted a mac app for Notarization. For the first few tries the Notarization failed with an error "Team is not yet configured for Notarization" but few days after my account started to show "ENROLL" option again even though my membership was set to expire on 2026. I am doubting my account has been suspended. I have not received any emails from apple regarding the suspension. I have contacted support but no help yet ! This was the second year, i was paying for the membership. Could you please help me to - Help me get the account unsuspended (if it is, as there is no notification or information regarding this) If the account is suspended due to my app being submitted for Notarization then help me identify the reason so that i can fix them.

I am a complete novice and I find that I cannot restore or delete the “Apple Development” certificate (I only use it for signing). From what I understand, you need to be in a program to manage certificates, but I have no intention of distributing any applications and, from my point of view, it makes no sense to pay. Am I wrong or am I doing something wrong? Notes: This happened after I installed Tahoe on a new installation. I was able to restore it using a copy of the keychains folder I had from Sequoia. Xcode (Apple Accounts - Manage Certificates) now shows me two certificates, indicating that one is not in the keychain and cannot be deleted.

The attached file bellow contains the full error error I clone this repo to my mac, change team id and group, and run it in Xcode: https://github.com/protonpass/ios-pass There's no issue when I ran it with the Debug configuration, but when I go to Product > Scheme > Edit Scheme and change the iOS target build configuration to Release then I got that error above. I have tried Archive and export the ipa, verify that the provisioning profile contains my Mac UDID, but when double clicking the ipa to install, I also got the error This app cannot be installed because its integrity could not be verified.

Hi, I have a .NET MAUI app which I've added subscriptions to using the Plugin.InAppBilling nuget package. When I tested on TestFlight I got an almost immediate crash. After doing some research I followed advice to add an Entitlements.plist file to Platforms &gt; iOS with the following entry: com.apple.developer.in-app-purchase The distribution provisioning profile I'm using to sign my app has the App ID set to an Identifier which has "In-App Purchase" ticked, but greyed out in it's "Capabilities" section on https://developer.apple.com/. I'm not sure why it's ticked and greyed out, but I assume that means that "In-App Purchase" is enabled. The app runs file locally but when I create an IPA file and add it to Transporter for upload to App Store Connect I get the following error: "Validation failed (409) Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on iOS. Specifically, key 'com.apple.developer.in-app-purchase' in 'Payload/[Removed].app/[Removed]' is not supported. (ID: [Removed])". Here is the structure of my csproj code for creating a IPA file for iOS: The command I use: dotnet publish [Removed]/app.csproj -f:net9.0-ios -c:Release ^ /p:PlatformTarget=Arm64 ^ /p:RuntimeIdentifier=ios-arm64 ^ /p:ServerAddress=[Removed] ^ /p:ServerUser=[Removed] ^ /p:ServerPassword=[Removed] ^ /p:ArchiveOnBuild=true ^ /p:BuildIpa=true I'm stuck trying to figure this out. If you could please point out any issues with what I'm doing or if you have any suggestions to resolve the problem I would very much appreciate it. Thanks, Ben

I'm working on an app that needs access to device activity. When I add device activity entitlement, I'm getting Provisioning profile "..." doesn't include the com.apple.developer.deviceactivity entitlement. This is failing for both, the main app and the extension, and both have entitlements added. It is not clear how to add it to the profile, the provisioning profile is created/managed by XCode. When I remove the entitlement, I can build my app but it won't be able to use device activity data I reached out to Developer Support, and they sent me here. What is the right way to add device activity entitlement? I'm also seeing another issue with XCode Cloud builds. When I remove device activity entitlement. I can build my app w/o any issue, and I can also install it directly on my iPhone. However, XCode Cloud builds fail wit Run command: 'xcodebuild -exportArchive -archivePath /Volumes/workspace/tmp/d41fc2f1-4f39-4906-8941-112488e75f6c.xcarchive -exportPath /Volumes/workspace/adhocexport -exportOptionsPlist /Volumes/workspace/ci/ad-hoc-exportoptions.plist '-DVTPortalRequest.Endpoint=http://172.16.68.193:8089' -DVTProvisioningIsManaged=YES -IDEDistributionLogDirectory=/Volumes/workspace/tmp/ad-hoc-export-archive-logs -DVTSkipCertificateValidityCheck=YES -DVTServicesLogLevel=3' I suspect that it could be related to my app having DeviceActivityExtension but no device activity entitlement is present. Thanks, Peter.

We recently had an external pentest for one of our company's macOS applications and they brought up the topic of library validation. Our app has hardened runtime enabled and passes notarization. The codesign verification output includes: flags=0x10000(runtime) The pentesters brought up that both validation and runtime should be present, so I discovered that you could also add library validation by augmenting our flags with: OTHER_CODE_SIGN_FLAGS = --timestamp -o library which changes the flags to: flags=0x12000(library-validation,runtime) The pentesters insist that both options are necessary, especially to avoid library injection when SIP is off, but Apple's docs say that hardened runtime already implies library validation (see here ) My question is: does explicitly specifying library validation provide something that hardened runtime does not already? Or is it correct that hardened runtime already imply library validation? For what it's worth, I did a quick scan of some of the apps on my system, interesting some of the Apple system apps have only library validation (e.g. Safari, Photos), some have both (e.g. Podcasts), some have only hardened runtime (e.g. Mail). So that didn't help answer the question. Thank you!

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?

The docs here outline how to create a CSR/ and request a certificate. https://developer.apple.com/help/account/certificates/create-a-certificate-signing-request "Accounts preferences Use Accounts preferences to manage developer account assets (signing certificates and provisioning profiles), add repositories, and add servers. To open Accounts preferences, choose Xcode > Preferences and click Accounts." I have the latest version of XCode, I don't see Preferences / Accounts anywhere? I can go here and create a certificate: https://developer.apple.com/account/resources/certificates/add but it wants a CSR, which loops back around to the XCode thing. So, I can't figure out how to create a singing cert for my iOS app. Launch Keychain Access located in /Applications/Utilities. This doesnt seem to exist in Mac OS Sequoia 15.5 https://developer.apple.com/help/account/certificates/create-a-certificate-signing-request

I have 14 total devices, from way back. I am currently in a financial bind and can't renew just yet. BUT I am at past my time to reset the device list back to zero. But the screen to do that is behind the paid account. Catch 22 Can we fix it? As it stands I must email tech support, but this is a bug so I posted

Hey, So i am trying to setup OpenGL on my mac. Specs : M2 Pro, 15.5 (24F74) Now i have setup the entire project properly as far as i know. GLFW, GLAD and the OpenGL framework. the build libraries are also reference and everything. I have also included the glad.c file in the folder. i have also kept it to run locally in signing tab. its still giving me Command CodeSign failed with a nonzero exit code All the ss are provided

Hi, I'm trying to integrate with Tap to Pay feature under Stripe. For this reason i need to add com.apple.developer.proximity-reader.payment.acceptance entitlement to my Identifier. I can see it under Provisioning Profile -> Enabled Capabilities. But after downloading this profile in Xcode I don't see this entitlement. What could be the reason for this discrapency?

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!
