Signing Certificates for MDM Configuration Profiles
Subject: Questions Regarding Signing Certificates for MDM Configuration Profiles Dear all, I hope this message finds you well. I have some questions regarding the signing certificates used for MDM configuration profiles. Currently, our company uses an SSL certificate to sign MDM configuration profiles. However, with the announcement that the validity period of SSL certificates will gradually be shortened starting in 2026, we are considering alternative options for signing certificates. Through our internal testing and investigation, we have found examples of the following certificate chains being used: ・Developer ID - G1 (Expiring 02/01/2027 22:12:15 UTC) + Developer ID Application certificate chain ・Apple Root CA + Apple Worldwide Developer Relations Intermediate Certificate + MDM CSR certificate chain We would appreciate any insights or experiences you can share regarding the following points: Apple Support previously advised that "certificates issued by public certificate authorities (CAs) trusted by Apple" are recommended. The certificates listed at https://www.apple.com/certificateauthority/ are typically preinstalled on Apple devices. Are these considered "trusted public CAs" by Apple in this context? Is it acceptable in practice to use a certificate obtained from the “Certificates, Identifiers & Profiles” section on developer.apple.com for signing MDM configuration profiles? We would be grateful to hear about any real-world experiences. If the answer to question 2 is yes, which certificate type within “Certificates, Identifiers & Profiles” would be most appropriate for signing configuration profiles? If using certificates from question 2 is not suitable, are there alternative certificate types (other than SSL) that are valid for longer periods (e.g., more than one year) and appropriate for signing MDM configuration profiles? Apple's official documents do not seem to clearly specify what type of certificate should be used to sign MDM configuration profiles. If you know of any helpful documents or resources related to this topic, we would greatly appreciate it if you could share them. Thank you very much for your time and support. We would truly appreciate any advice or guidance you can provide.

Encounter "zsh: trace trap" after updating trust settings for Apple certificates
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 (???)

Missing com.apple.developer.voip-push-notification Entitlement in Provisioning Profile
Hello Everyone, I am currently building an app using React Native with Swift bridging, integrating VoIP functionality using Twilio, PushKit, and CallKit. I am encountering the following issue during development: "The current provisioning profile doesn't include the com.apple.developer.voip-push-notification entitlement." What I’ve Done So Far: VoIP Certificate: I have created a valid VoIP Services certificate in the Apple Developer portal. Bundle Identifier and Provisioning Profile: A new Bundle ID was created specifically for this app. I created a provisioning profile for this Bundle ID and downloaded it for use in Xcode. Xcode Capabilities Push Notifications: Enabled Background Modes: Voice over IP: Enabled, Remote notifications: Enabled Entitlements File I have an entitlements file named VoiceCallDemoProjectRelease.entitlements with the following content: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>aps-environment</key> <string>development</string> <key>com.apple.developer.voip-push-notification</key> <true/> </dict> </plist> This entitlements file is properly linked in the project’s build settings. Project Setup I have integrated PushKit for VoIP push handling and CallKit for incoming call UI and control. Problem: In the Apple Developer portal under my App ID settings, I only see an option to enable Push Notifications. There is no option available to enable Voice over IP, and therefore the provisioning profile generated does not include the com.apple.developer.voip-push-notification entitlement. Despite enabling VoIP background mode in Xcode, adding the entitlement in my project, and using a valid VoIP certificate, the profile does not include the required entitlement. Additional Information: I am using an Individual Apple Developer Account, not an Organization account. I have already attempted re-downloading the provisioning profile, restarting Xcode, and cleaning the build folder. Question: What steps should I take to resolve this and ensure that the com.apple.developer.voip-push-notification entitlement is included in my provisioning profile? Is this limitation due to the type of developer account (individual vs. organization), and do I need to upgrade to an Organization account to access this entitlement? Is there any way to request for 'com.appple.developer.voip-push-notification' entitlement to Apple Team ? Any clarification would be appreciated. Thank you.

Provisioning profile doesn't support the Sign in with Apple capability.
Hi! I'm trying to add Sign in with Apple to my macOS app. I enabled this capability from the developer portal and created the corresponding certificate & provisioning profile (both of type Developer ID Application.) However, Xcode keeps prompting me that the profile doesn't support Sign in with Apple. If I enable Automatically manage signing from Xcode, I can build and run the app but not distribute. If I turn it off and use the profile I got, it just keeps showing the errors below and doesn't even let me build.

Moving signing to a new machine
We have a Mac that is used to sign and notarize our installers. This Mac will be going away soon, so I have to setup a new Mac to do that work. I've been able to install all the tools, but I can't get them to work. The certificates are in the keychain, but don't show up in the "My Certificates", probably because the related keys don't exist in the "Keys" list. I'm using the same Apple Dev ID that I used on the other machine. HOW do I get things setup on the new machine to work? There must be some way to get key/certificate pairs to work. (I am very definitely NOT a Mac expert, barely even a novice.)

Maximum Development Certificates?
I recently had to update my certificates for a project. I deleted a few old ones, and I currently have one Development certificate. I needed to create another Development certificate specifically, it's saying "Maximum number of certificates generated." I thought the maximum was two Development certificates? Has anyone else had this issue? Thinking it could be a stuck workflow or something like that.

App Groups Entitlement Mismatch Between Provisioning Profile and Xcode Requirements for iOS App Extension
Hello Apple Developer Community, I'm experiencing a persistent issue with App Groups configuration for an iOS app extension that I can't resolve despite trying multiple approaches. I hope someone can help identify what I'm missing. Problem Description I'm getting this error when trying to build my iOS App Extension: Provisioning profile "iOS Team Provisioning Profile: com.idlrapp.Spleeft.SpleeftDataSaver" doesn't include the com.apple.developer.app-groups entitlement. My Setup Main App Bundle ID: com.idlrapp.Spleeft Extension Bundle ID: com.idlrapp.Spleeft.SpleeftDataSaver App Group ID: group.com.idlrapp.spleeft.shared Extension Type: Action Extension (Share Sheet) What I've Verified App Group Creation ✅ Created App Group group.com.idlrapp.spleeft.shared in Apple Developer Portal ✅ App Group shows as "Active" in the portal App ID Configuration ✅ Both App IDs (com.idlrapp.Spleeft and com.idlrapp.Spleeft.SpleeftDataSaver) have "App Groups" capability enabled ✅ Both App IDs are configured with the same App Group: group.com.idlrapp.spleeft.shared Entitlements Files Main App (Spleeft.entitlements): <key>com.apple.developer.app-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> Extension (SpleeftDataSaver.entitlements): <key>com.apple.developer.app-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> Xcode Configuration ✅ Both targets use "Automatically manage signing" ✅ Same Apple Developer Team selected for both ✅ App Groups capability shows correctly in Signing & Capabilities for both targets The Issue When I examine the downloaded .mobileprovision file, I can see it contains: <dict> <key>com.apple.security.application-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> <!-- Other entitlements... --> </dict> However, Xcode expects to find: <array> <string>group.com.idlrapp.spleeft.shared</string> </array> What I've Tried Multiple regenerations of provisioning profiles: Deleted all local provisioning profiles Toggled "Automatically manage signing" off/on Downloaded manual profiles from Developer Portal Verified App Group configuration: Double-checked App Group exists and is active Confirmed both App IDs have App Groups capability enabled Verified App Group assignment in both App IDs Entitlements cleanup: Ensured consistent App Group IDs across all files Removed duplicate/conflicting entries Clean builds and cache clearing: Product → Clean Build Folder Derived Data deletion Xcode restart Key Observation The provisioning profile contains com.apple.security.application-groups (which appears to be macOS-style) but Xcode expects com.apple.developer.app-groups (iOS-style) for the App Extension. Questions Is there a known issue with App Groups entitlement generation for iOS App Extensions? Should the provisioning profile contain com.apple.developer.app-groups instead of com.apple.security.application-groups? Is there a way to force regeneration of provisioning profiles with the correct entitlements? Are there additional steps required for App Extensions that differ from main apps? Any guidance would be greatly appreciated. This is blocking our App Extension development and we've exhausted our troubleshooting options. Thank you for your time and assistance.

Developer ID certificate not working after Apple ID password change
Hi everyone, After I recently changed my Apple ID (iCloud) password, my Developer ID certificate stopped working for signing macOS apps. Symptoms: Signing fails with the Developer ID certificate that was previously working fine. I tried re-downloading the certificate from my Apple Developer account and importing it into the Keychain, but the issue persists. It seems that the Developer ID identity is no longer trusted or properly linked to my system since the password change. Attempts: Re-downloaded and installed the certificate from the developer portal. Verified that the private key is present and linked. Checked keychain access and code-signing identity — everything appears normal, but the signed apps are rejected or the signing process fails. Blocking issue: I am unable to delete or revoke the Developer ID certificate on my account (Apple Support says it's not possible). Also, I can't create a new one due to the certificate limit. Questions: Is it expected for a Developer ID certificate to become invalid after changing the Apple ID password? Is there a recommended way to refresh or restore the certificate trust on macOS? How can I invalidate the current certificate and generate a new one if I'm stuck? Any insights or official guidance would be really appreciated. Thanks in advance!

Exporting valid certificate as .p12
I have a valid Developer ID Certificate, I've used it to sign an app locally and send the app to other machines of my colleagues to make sure it works and does not get triggered by GateKeeper Now I want to automate the process of signing and notarization on github actions and so I want to export my certificate and upload it there. Initially I tried uploading both the Developer ID Certificate and the G2 CA both as .cer files encoded in base64. But apparently I need my certificate to be in .p12 format When I try to export it from keychain access the option to export as .p12 is disabled. So how can I do it ?

DEVELOPER_ID_APPLICATION_G2 is not recognized by ASC API
Hi, ASC API call rejects DEVELOPER_ID_APPLICATION_G2 and does not recognize it, even though it is listed as a valid certificateType in the docs: https://developer.apple.com/documentation/appstoreconnectapi/get-v1-certificates. If it was removed from the certificate list, then why Apple forces to choose the G2 type when creating a DEVELOPER_ID_APPLICATION certificate manually in the Apple Developer account. Can someone from Apple support please check it as it is a contradictory behavior and is a blocker.

Push Notifications Failing - Xcode shows "Untitled" Certificates & "No App ID" for Push Console after Org Account Migration
Hi everyone, I recently migrated my individual Apple Developer account to an Organization account for my company "". My Team ID remained the same. I'm now facing persistent issues with code signing and push notifications for my iOS app (Bundle ID: com.).
 Current Problems:
 "Untitled" Certificates in Xcode: When I go to Xcode -> Settings -> Accounts -> [My Apple ID] -> Select "" Team -> "Manage Certificates...", a number of my newly created Apple Development and Apple Distribution certificates are listed древ "Untitled". Some older ones are "Revoked". (See attached screenshot if possible).
 "No App ID" for Push Notifications Console: In my app target's "Signing & Capabilities" tab, I've added the "Push Notifications" capability. However, when I click the info button to open the "Push Notifications Console", it states: "no app IDs: Register an App ID with the Push Notifications capability enabled to use the Push Notifications console." This is despite the fact that the Push Notifications capability IS enabled for my App ID com. in the Developer Portal, and I've configured an APNs Auth Key (.p8) for it.
 Push Notifications Not Received (from Backend): While I can successfully send a test push notification directly from the Firebase Console to my device's FCM token, notifications triggered by my backend (Firebase Cloud Functions writing to a Firestore collection, which then triggers another function to send via FCM) are not being delivered to iOS devices. (Android seems to be working more reliably now).
 Setup: Using an APNs Authentication Key (.p8) linked to my Organization Team ID in Firebase Cloud Messaging. Main App ID com. has "Push Notifications" capability enabled. Notification Service Extension com..ImageNotification also has its App ID and Provisioning Profile set up for the Organization team. Created new Development and Distribution certificates and Provisioning Profiles specifically for the Organization team. Using "Automatically manage signing" in Xcode with the Organization team selected for both the main app target and the extension target.
 Troubleshooting Done: Revoked old/problematic certificates and profiles. Recreated CSRs and new Development/Distribution certificates under the Organization team multiple times. Recreated Provisioning Profiles. Cleaned Derived Data in Xcode. Ensured Bundle Identifiers are consistent. Verified APNs Auth Key details (Key ID, Team ID) in Firebase.
 I suspect there's a fundamental issue with how Xcode is recognizing or linking the signing assets for my Organization team after the account type change, despite the Team ID being the same. The "Untitled" certificates are a major red flag.
 Has anyone encountered similar issues, particularly the "Untitled" certificates or the "No App ID" message for the Push Console, after an account migration or when working with Organization accounts? Any insights on how to resolve this would be greatly appreciated.
 Thanks,
Benni

Notarization Fails: “The binary is not signed with a valid Developer ID certificate” for Flutter macOS App Plugins (file_picker, file_saver, url_launcher_macos)
Hi all, I’m trying to notarize a Flutter macOS app built in CI (GitHub Actions). The app builds and signs fine locally—codesign --verify --deep --strict and spctl --assess both pass. However, Apple’s notarization service consistently rejects the app with errors like: The binary is not signed with a valid Developer ID certificate: file_picker.framework The binary is not signed with a valid Developer ID certificate: file_saver.framework The binary is not signed with a valid Developer ID certificate: url_launcher_macos.framework What I’ve tried: Explicitly re-signing all frameworks with my Developer ID Application certificate and --timestamp Removing existing signatures before re-signing Ensuring correct entitlements and bundle identifier Matching the app bundle name and identifier in all places Using both codesign --deep and manual signing of each binary Local validation always passes, but notarization fails in CI Certificate: I am using a “Developer ID Application” certificate (not a “Mac Developer” or “Apple Development” certificate). The output of codesign -dvv for the problematic frameworks shows: Authority=Developer ID Application: [My Name/Team] ([Team ID]) So I believe I am not making the common mistake of using the wrong certificate type. CI Environment: GitHub Actions, macos-latest runner Flutter 3.27.2, stable channel All secrets (cert, Apple ID, app-specific password, team ID) are set up Questions: Has anyone encountered this with Flutter plugins or CI builds? Are there known issues with signing Flutter plugin frameworks for notarization? Is there a way to get more detailed feedback from Apple’s notarization service? Any advice or pointers would be greatly appreciated. I’m happy to provide logs, scripts, or a minimal project if needed. Thanks!

Issues Signing .app with Developer ID Certificate — Missing Private Key and Pipeline Concerns
I’m having issues trying to codesign a .app file. We generated the Developer ID Application certificate using the organization owner’s account. I downloaded the certificate to my Mac and imported it into my keychain, but when I run the codesign command below, I get the following error. Could you help me? What am I doing wrong? Is there any other way to sign the .app executable? From what I’ve seen in other posts, it looks like the certificate needs to have a private key, but the certificate I download from the developer portal doesn’t include the key. Also, about exporting it as a .p12 — I couldn’t quite understand if that’s considered a safe practice, since the organization owner’s private key would be included in this certificate that we plan to use in our pipeline.

CodeSign : errSecInternalComponent
I’ve been wrestling with this for nearly a week now and none of the proposed fixes have worked. I’m trying to resign an app via Jenkins and have done the following: Created a custom keychain Imported the required .p12 certificates Installed the Apple WWDR certificate in the System keychain Made the login keychain my default Added my development keychain, the login keychain and the System keychain to the user keychain list Unlocked my development keychain Confirmed my signing identity is present Granted the appropriate partition list access to the keychain "security set-key-partition-list -S apple-tool:,codesign: -k pwd /Users/ec2-user/Library/Keychains/development.keychain-db" Yet when I invoke Fastlane’s resign action, I still see: _floatsignTemp/Payload/EverMerge.app/Frameworks/AppLovinSDK.framework: replacing existing signature _floatsignTemp/Payload/EverMerge.app/Frameworks/AppLovinSDK.framework: errSecInternalComponent Encountered an error, aborting! Any guidance on what might be causing this errSecInternalComponent failure or how to get the resign step to succeed would be highly appreciated.

CodeSign with out Certificate and Profile
We are facing issue with resigning the app which is developed by 3rd party. In this app we have Sharing functionality feature for which we have enabled Associated Domains capability. When we are signing the app with our certificate and profile this functionality is not working i.e when we are clicking on shared link in the app it is redirecting to app store page instead of content link. However, when 3rd party is directly using our certificate & profile then that functionality is working as expected. Could you please help us with the above issue why it is not working when we are resigning with our certificate and profile?
