Notarization service says signature invalid, but codesign says it's fine
I'm trying to get an app notarized, which fails with this error: The signature of the binary is invalid. However, locally checking the signature does succeed: $ codesign -vvv --deep --strict TheApp.app […] TheApp.app: valid on disk TheApp.app: satisfies its Designated Requirement Performing this check on every single item in the app's MacOS folder also succeeds. Context: embedded prebuilt binaries Now, the app has something unusual about it: it embeds prebuilt binaries, arranged in various nested folders. So, the app bundle's MacOS folder actually contains another folder with a whole tree of executables and libraries: Removing these (before building) does fix the notarization issue, but obviously I'd like to keep them in. I did my best to properly sign these items: At build time, they're copied into the product by a Copy Files phase (but not signed), then signed by a script phase That signing uses the same signing identity as the running Xcode build, and enables the hardened runtime The app builds and runs correctly, even as a release build The app has runtime hardening and app sandbox enabled How should I go about diagnosing the notarization issue?

Notarising two builds of the same app
I have built my application for arm and x64 so I have two files called DeepSkyStacker.app in different directories. I have followed the instructions to notarise the arm version of the app, but an concerned about what I should do to notarise the other one - do I just zip that up and then run: xcrun notarytool submit "DeepSkyStacker.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple DeepSkyStacker.app again or will that mess everything up? Related to that can I use the Notary Profile I created for DeepSkyStacker to notarise other apps that are part of the same product (DeepSkyStackerLive and DeepSkyStackerCL)?? Thanks David

Disabling Hardened Runtime For Ad Hoc Signing Only
How can I disable Hardened Runtime in Xcode only when signing ad hoc? If I make a new project, Xcode will say Disabling hardened runtime with ad-hoc codesigning. at the beginning of the build logs. However, somehow my project isn't doing this -- it's still hardening the runtime when ad-hoc signing. What should I do to debug this?

Notarization stuck in progress for new Apple Developer Account
I use the 'notarytool' to notarize applications and .pkg installers for Developer ID distribution. When using the notary tool with a fresh Apple Developer account, the notarization process remains stuck in the 'In progress' state. However, if I try the same app with an older developer account (one that has notarized at least one app in the past), the notarization works. All agreements are accepted in developer portal and Appstore Connect.

Issue Regarding Notarization
I am trying to notarize a simple app I made, but keep getting stuck on "In Progress". The app is a MacOS app, and I'm using XCode. I've tried all the steps listed in the links below: https://developer.apple.com/documentation/security/notarizing-macos-software-before-distribution https://developer.apple.com/documentation/security/resolving-common-notarization-issues I've had the same issue with another app, which got rejected after multiple hours. Never got to resolve this.

App Sandbox & Missing Symbols for Nested PyInstaller App Bundle
Hi Developers, I'm encountering persistent validation errors in Xcode 16.3 (16E140) on macOS 15.4.1 (24E263) with M1 when archiving and distributing a macOS app (Developer ID signing + notarization). App Structure: A native Swift/Obj-C wrapper app that launches a nested .app inside its Resources. The nested app is built with PyInstaller and includes: A Python core Custom C++ binaries Many bundled .so libraries (e.g., from OpenCV, PyQt/PySide) Issues During Validation: App Sandbox Not Enabled Error: App Sandbox missing for NestedApp.app/Contents/MacOS/NestedExecutable. Question: For Developer ID (not App Store), is sandboxing strictly required for nested PyInstaller apps? If the wrapper is sandboxed, must the nested app be as well? Given the PyInstaller app's nature (requiring broad system access), how should entitlements be managed? Upload Symbols Failed Errors for missing .dSYM files for: The nested app’s executable Custom C++ binaries .so files (OpenCV, PyQt, etc.) These are either third-party or built without DWARF data, making .dSYM generation impractical post-build. Question: Are these symbol errors critical for Developer ID notarization (not App Store)? Can notarization succeed despite them? Is lack of symbol upload a known limitation with PyInstaller apps? Any best practices?

Is it Possible to Have Stray Content in a macOS Framework?
Is it possible to have some additional content at Versions/A/ in a macOS Framework bundle that is not in any of the standard folders? Will there be any side-effects during signing and notarization? The reason is it'd be a lot easier in my use case to be able to put content here instead of the Resources folder.

Have not been able to notarize for the past 2 days
I haven't been able to notarize my macOS app for the past two days. Now, I believe this is an issue with the notarization process because I've tried notarizing the default app that's provided whenever you open a new Swift application, but that completely failed as well. And I've been waiting for the past two days and it's been stuck on in progress. This is the second time this has happened to me in the past two months and oftentimes I have to wait more than a day or two for the notarization to occur. I just, I don't understand why it's deadlocked like this. I've done nothing. I haven't changed my certificates. I haven't done any different configurations within my Mac. The last time that this happened, the issue went away after two days, but my biggest concern right now is that if this happens whenever we need to urgently push updates, we can't. I have absolutely no idea what to do and I'm just extremely frustrated because this is happening right before our launch day. I've been stuck on notarizing again for the past two days and I've seen no progress, I've seen no responses from support emails and the ones that do aren't even applicable to my current scenario. ⁠

Apple Notarization: Long running notarization jobs / day limitation
Dear Apple support, Since the last couple of days, we have some (very) long running notarization requests. Similar requests were done normally under 1 minute. This behavior is unexpected to us, and we did not see it before. The issue occurs for a small CLI tool submitted as a ZIP archive. Checking the documentation, I come across the section about "Avoid long notarization response times and size limits" (https://developer.apple.com/documentation/security/customizing-the-notarization-workflow#Avoid-long-notarization-response-times-and-size-limits). One fact is mentioned “Limit notarizations to 75 per day.” What is behavior if that limitation is reached? Is that limitation per Apple ID or per team ID? Are there some known issues about Notarization Service? Best regards, Stefan

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.

productbuild hangs with no output in github actions
I am running into this error with productbuild in github actions where the program hangs with a specific developer id. I have verified that my certification files are properly uploaded etc. and i am able to run this without the --sign command online and with --sign offline. if i sign with a "3rd party mac developer installer: ***" it will run but then crash on stapling because this isn't the actual org i want to staple and don't really need to verify that i could staple with this other license since it is my personal license and i will be leaving this job soon so setting up all my other certs is a waste of time since it doesn't solve the problem. When i use my bosses/org "Developer ID Installer: ***" productbuild just hangs. I am at a loss here... the acutal command running is productbuild --resources ./resources --distribution distribution.xml --sign "${{ secrets.DEVELOPER_ID_INSTALLER }}" --timestamp "${{ env.ARTIFACT_NAME }}.pkg" I have confirmed that my distribution file is fine etc. because I can productbuild without signing fine. Any suggestions on where to go?

I can't distribute the build to Testflight
Hi the best community! When I try to submit the app to Testflight I receive the following error: "codesign command failed (/var/folders/j9/yh_rkh114rbgvmglf4gycj8w0000gn/T/XcodeDistPipeline.~~~OW0Dwk/Root/Payload/Application.app/Frameworks/Alamofire.framework: replacing existing signature /var/folders/j9/yh_rkh114rbgvmglf4gycj8w0000gn/T/XcodeDistPipeline.~~~OW0Dwk/Root/Payload/Application.app/Frameworks/Alamofire.framework: invalid or corrupted code requirement(s) Requirement syntax error(s): line 1:155: unexpected token: NPH )" I have never stuck with this issue before. Xcode Version 16.0 I assume that there is something related to code signing and our company name in App Store connect: Medical Institution “NPH” (The company name has been anonymized for privacy purposes.) Appreciate any help. Thank you!

Notarization is not ever finishing
Hello, I had a successful attempt at notarization earlier today in my build pipeline. I've been using the same system for building my macOS application for over a year now. However, subsequent builds seemed to fail. I found a couple similar topics which makes this seem not not an isolated incident: https://developer.apple.com/forums/thread/782950 https://developer.apple.com/forums/thread/783347 https://developer.apple.com/forums/thread/783283 In my case I use the following command to submit the notarization: xcrun notarytool submit FilePath.dmg --apple-id "myappleid@gmail.com" --password "redacted_obviously" --team-id "my-team-id" --wait I left a previous run go for over an hour and the "Current status: In Progress.................. etc" filled the whole terminal. I manually checked the progress of the submissions using the command below: xcrun notarytool log --apple-id "myappleid@gmail.com" --password "redacted_obviously_again" --team-id "my-team-id" [run id] And they all result in the following output: Submission log is not yet available or submissionId does not exist Is anyone else experiencing this? Are there any possible solutions?

App Signing and Uploading Intel/Apple
Hello, I am normally a windows programmer, but I am trying to get my PySide/Qt app into the app store. I'm almost there, I just have a couple of questions about the signing process. I have two laptops, one intel silicon, one mac silicon. I created 2 CSR's, one on each laptop and used them to generate 2 Mac Installer Distribution certificates and 2 Mac App Distribution certificates. When it came to downloading the provisioning profile, I selected one Mac App Distrbution Certificate on the interface at developer.apple.com, saved it and then downloaded to the appropriate laptop. I then switched the provisioning profile to the other Mac App Distribution Certificate and downloaded it to the other laptop. I then built the app and uploaded everything using xcrun altool. On the intel machine only(which has the first provisioning profile) I successfully uploaded the package but I get an email identifying lots of similar errors of the type (Lets call it error1): ITMS-90284: Invalid Code Signing - The executable XXXXX must be signed with the certificate that is contained in the provisioning profile. On the ARM machine only i get the following error (Lets call it error2): ITMS-91109: Invalid package contents - The package contains one or more files with the com.apple.quarantine extended file attribute, such as XXXXXXXX embedded.provisionprofile”. This attribute isn’t permitted in macOS apps distributed on TestFlight or the App Store. Please remove the attribute from all files within your app and upload again. On both I get the following error lets call it error3: ITMS-90886: 'Cannot be used with TestFlight because the signature for the bundle at XXXXX is missing an application identifier but has an application identifier in the provisioning profile for the bundle. Bundles with application identifiers in the provisioning profile are expected to have the same identifier signed into the bundle in order to be eligible for TestFlight.' My first inclination is that all the error1's are coming from having two sets of CSRs, Mac Distribution certificates, provisioning profiles etc. Should I have only used one CSR and made one each of the Certificates? I don't know why I have error2. I don't know where the quarantine attribute is coming from and why it would affect the mac silicon and not the intel. Any ideas? my entitlements file has the following: <key>com.apple.security.cs.allow-jit</key> <true/> <key>com.apple.security.cs.allow-unsigned-executable-memory</key> <true/> <key>com.apple.security.cs.disable-library-validation</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.device.bluetooth</key> Error3 is the one where I need to try a few things but knowing what is expected will help. In the provisioning profile when viewed at developer.apple.com it has the APP ID listed as the 10 digit id followed by the bundle ID but I sometimes see just the 10 digit app ID being used and sometimes the bundle ID. I know that it's up to me to figure out how to get it into the build, but knowing what it should be would be helpful. On the other hand the text "Bundles with application identifiers in the provisioning profile ..." indicates that if the application identifier was not in the provisioning profile i might get away with it, but this might be grasping at straws. If you have made it this far, thank you for reading.

Notarization Stuck for Signed .pkg Containing Screen Saver
Hey all, I’m experiencing a consistent issue with notarizing a signed .pkg file that contains a macOS screen saver (.saver) bundle. Nothing online so far except 1 thread on the form from the altool time pre-2023 so i thought it worth another update. Here is what I did: I signed the .saver bundle using my Developer ID Application certificate. I packaged it into a .pkg using pkgbuild with my Developer ID Installer certificate: I submitted the resulting .pkg via xcrun notarytool: xcrun notarytool submit saver-name.pkg --apple-id email@email.com --password [app-specific-password] --team-id xxxxxxxxx The submission appears to be accepted and uploads successfully. However, the notarization status remains stuck at “In Progress” for hours (over 12h), with no update. I also tried: Repackaging the .pkg with a new name using a zip Resubmitting it under a new submission ID All attempts are stuck in the same “In Progress” state indefinitely. Did anyone solve this yet?
