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!

Dear Apple Support,
for better understanding to use the Notary Service, I would like to ask when and what have to be notarized.
I am absolutely aware of using the Notary Service and which packages can be submitted and how to get the status.
Scenario:
We have one library which is developed by a specific team and other teams develop and deliver to customer MacOS apps which packages this library for the shipment.
So, the library will be produced internally and will be shipped in different products.
The library will be code signed before we make available internally.
When should we notarize (and staple) this library?
Directly after the code is signed or when it will be packaged in each product when it will be delivered to customer?
Best regards,
Stefan
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.

I have attempted all upgrades:
updated xcode to 16.4
downloaded and installed Command Line Tools for Xcode 16.4
I have no issues with the installs, however when I run:

I need to be running v2.x
How can I resolve this issue.

I'm not entirely sure what's causing this issue. Has anyone else encountered this error while signing their macOS app? I’d really appreciate any guidance or solutions you can share.

Yesterday there were reported outages on the Developer ID Notary Service, but it was reported pretty late and we were able to notice the outages in real time. It says resolved now, however an error still persists:
Error: HTTP status code: 403. A required agreement is missing or has expired. This request requires an in-effect agreement that has not been signed or has expired. Ensure your team has signed the necessary legal agreements and that they are not expired.
Is there an ongoing outage at this moment that is not being reported again?
Our pipelines have been working flawlessly for months without intervention nor changes until the most recent outages
I'm building a custom macOS installer for my software, primarily using the builtin tools of codesign, pkgbuild, productbuild and xcrun.
My product consist of a list of plugins and a CEP extension for the Adobe After Effect app.
All of my bundles and binaries are properly signed using a trusted Apple Developer certificate I've generated, of type Developer ID Application.
My installer is a "distribution" pkg, and has this structure(expanding it using pkgutil --expand):
SceneTools-3.4.4-osx-installer
├── Distribution
├── miscellaneous.pkg
├── plugins.aftereffects2022.pkg
├── plugins.aftereffects2023.pkg
├── plugins.aftereffects2024.pkg
├── plugins.aftereffects2025.pkg
├── preinstall.pkg
├── Resources
├── scenebuilder.pkg
└── uninstaller.pkg
Each "child" pkg would install parts of my product in different locations in the target macOS disk(this is why I'm using that kind of style of building the custom installer).
Signing each and every bundle or binary of my product, signing the "child" pkg's, then notarizing them works well with no issues, in addition signing the "final" "distribution" using productbuild --sign option also works well, but when trying to notarize the "final" pkg, the notary service fails with this error:

}
My final pkg indeed doesn't contain any bundles or binaries directly, but that's how it should be - a container of "child" pkg.
I tried various ways of working-around this issue, like:
Notarizing the dmg that contains this final pkg - worked, but when opening the pkg, GateKeeper blocks the users from opening it.
Wrapping the pkg inside an .app and notarizing the .app - same as above.
What am I doing wrong?
Does those kind of pkg like my "final" pkg aren't meant to be notarized? if so - how can I solve this GateKeeper blocks?
Should I build my final pkg in a different way?

Request:
Could you please help investigate:
Why is the stapler unable to validate or attach the ticket even though notarization completes successfully?
Are there any known issues, entitlements, or workflow adjustments recommended in this case?
Is any special handling required for Electron apps’ PKG/DMG packages or Hardened Runtime configurations during stapling?
I can provide the signed DMG/PKG and full notarization logs upon request.
Thank you very much for your assistance — looking forward to your guidance.

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.

Hi guys,
I am new to publishing apps on Apple Store. I used python, pyside6, torch, pyinstaller to build an app for Apple Store.
For codesigning, I used the correct "Developer ID Application" to sign the code. When I validate the .app file (codesign -vv --strict ), I got the following
my_app.app: valid on disk
my_app.app: satisfies its Designated Requirement
Next, I used ditto to "ditto -c -k --sequesterRsrc --keepParent my_app.app my_app.zip" to zip it.
Then, I submitted this my_app.zip file for notarization with "xcrun notarytool submit ..." and got the following "accepted" message.
Received new status: Accepted
Current status: Accepted...............
[20:08:54.530Z] Info [API] Submission in terminal status: Accepted
Processing complete
After that, I want to staple it with "xcrun stapler staple my_app.app", but I got the following
Could not validate ticket for my_app.app
The staple and validate action failed! Error 65.
To further investigate it, I ran "spctl -a -vvv my_app.app" and got
my_app.app: rejected
source=Unnotarized Developer ID
origin=Developer ID Application...
I don't know why this would happen after notarization accepted. Could someone help me understand this issue? Thanks!

Hello,
I'm currently trying to upload a new version of an existing application. But each time I try to validate the archive of the application, I got the following error in Xcode (v16.2) :
Invalid code signing entitlements. Your application bundle’s signature contains code signing entitlements that aren’t supported on macOS. Specifically, the “37CG5MY799.com.example.app” value for the com.apple.application-identifier key in “com.example.app.pkg/Payload/app.app/Contents/MacOS/app” isn’t supported. This value should be a string that starts with your Team ID, followed by a dot (“.”), followed by the bundle ID.
I suspect that there is a problem with the App ID Prefix (that is 37CG5MY799 for the app) when our team ID is E4R7RJ7LA3 but I cannot find a solution.
I asked the Apple Developer Support for help and I have read the documentation they sent but it couldn't solve this problem so they redirected me to the forums.
https://developer.apple.com/library/archive/qa/qa1879/_index.html
https://developer.apple.com/library/archive/technotes/tn2318/_index.html#//apple_ref/doc/uid/DTS40013777-CH1-OVERVIEW
https://developer.apple.com/library/archive/technotes/tn2318/_index.html#//apple_ref/doc/uid/DTS40013777-CH1-TNTAG33
There isn't any obvious App ID Prefix mismatch in the entitlement between the Application's signature entitlement and the Embedded provisioning profile entitlement .
Application's signature entitlement :
<dict>
<key>com.apple.application-identifier</key>
<string>37CG5MY799.com.example.app</string>
<key>com.apple.developer.team-identifier</key>

<true/>
</dict>
Embedded provisioning profile entitlement :
<dict>
<key>com.apple.security.application-groups</key>
<array>
<string>group.com.example.app</string>
<string>E4R7RJ7LA3.*</string>
</array>

</array>
<key>com.apple.developer.team-identifier</key>
<string>E4R7RJ7LA3</string>

The app also have a browser extension that correctly use the Team ID.
How to solve this problem ?

I have an application that I have been signing, notarizing and distributing to beta testers for a year with no issues, note: I have never got stapling to work I always get a error 65 in the process. But up until yesterday that hasn't been an issue and online verification has always worked. Yesterday morning around 9am online gatekeeper verification has been failing with:
APP not opened,
apple cannot verify app is free of malware. etc
this keeps happening, with every build I try. redownloading previously successful builds show the same behavior
I know I can allow in privacy and security, but heading towards launch I dont want to have to tell users to do that.
has there been a change in how gatekeeper works or issues with the service?
any help with this or getting stapling working would be very appreciated!
The notary service requires that all Mach-O images be linked against the macOS 10.9 SDK or later. This isn’t an arbitrary limitation. The hardened runtime, another notarisation requirement, relies on code signing features that were introduced along with macOS 10.9 and it uses the SDK version to check for their presence. Specifically, it checks the SDK version using the sdk field in the LC_BUILD_VERSION Mach-O load command (or the older LC_VERSION_MIN_MACOSX command).
There are three common symptoms of this problem:
When notarising your product, the notary service rejects a Mach-O image with the error The binary uses an SDK older than the 10.9 SDK.
When loading a dynamic library, the system fails with the error mapped file has no cdhash, completely unsigned?.
When displaying the code signature of a library, codesign prints this warning:
% codesign -d vvv /path/to/your.dylib
…
Library validation warning=OS X SDK version before 10.9 does not support Library Validation
…
If you see any of these errors, read on…
The best way to avoid this problem is to rebuild your code with modern tools. However, in some cases that’s not possible. Imagine if your app relies on the closed source libDodo.dylib library. That library’s vendor went out of business 10 years ago, and so the library hasn’t been updated since then. Indeed, the library was linked against the macOS 10.6 SDK. What can you do?
The first thing to do is come up with a medium-term plan for breaking your dependency on libDodo.dylib. Relying on an unmaintained library is not something that’s sustainable in the long term. The history of the Mac is one of architecture transitions — 68K to PowerPC to Intel, 32- to 64-bit, and so on — and this unmaintained library will make it much harder to deal with the next transition.
IMPORTANT I wrote the above prior to the announcement of the latest Apple architecture transition, Apple silicon. When you update your product to a universal binary, you might as well fix this problem on the Intel side as well. Do not delay that any further: While Apple silicon Macs are currently able to run Intel code using Rosetta 2, that’s not something you want to rely on in the long term. Heed this advice from About the Rosetta Translation Environment:
Rosetta is meant to ease the transition to Apple silicon, giving you
time to create a universal binary for your app. It is not a substitute
for creating a native version of your app.
But what about the short term? Historically I wasn’t able to offer any help on that front, but this has changed recently. Xcode 11 ships with a command-line tool, vtool, that can change the LC_BUILD_VERSION and LC_VERSION_MIN_MACOSX commands in a Mach-O. You can use this to change the sdk field of these commands, and thus make your Mach-O image ‘compatible’ with notarisation and the hardened runtime.
Before doing this, consider these caveats:
Any given Mach-O image has only a limited amount of space for load commands. When you use vtool to set or modify the SDK version, the Mach-O could run out of load command space. The tool will fail cleanly in this case but, if it that happens, this technique simply won’t work.
Changing a Mach-O image’s load commands will break the seal on its code signature. If the image is signed, remove the signature before doing that. To do this run codesign with the --remove-signature argument. You must then re-sign the library as part of your normal development and distribution process.
Remember that a Mach-O image might contain multiple architectures. All of the tools discussed here have an option to work with a specific architecture (usually -arch or --architecture). Keep in mind, however, that macOS 10.7 and later do not run on 32-bit Macs, so if your deployment target is 10.7 or later then it’s safe to drop any 32-bit code. If you’re dealing with a Mach-O image that includes 32-bit Intel code, or indeed PowerPC code, make your life simpler by removing it from the image. Use lipo for this; see its man page for details.
It’s possible that changing a Mach-O image’s SDK version could break something. Indeed, many system components use the main executable’s SDK version as part of their backwards compatibility story. If you change a main executable’s SDK version, you might run into hard-to-debug compatibility problems. Test such a change extensively.
It’s also possible, but much less likely, that changing the SDK version of a non-main executable Mach-O image might break something. Again, this is something you should test extensively.
This list of caveats should make it clear that this is a technique of last resort. I strongly recommend that you build your code with modern tools, and work with your vendors to ensure that they do the same. Only use this technique as part of a short-term compatibility measure while you implement a proper solution in the medium term.
For more details on vtool, read its man page. Also familiarise yourself with otool, and specifically the -l option which dumps a Mach-O image’s load commands. Read its man page for details.

Many notarisation issues are actually code signing or trusted execution issue. For more on those topics, see Code Signing Resources and Trusted Execution Resources.

Hi,
we have .pkg install package consisting of various sub packages. One of them contains presets and needs to be installed the the default preset location /Library/Audio/Presets. If this non-binary preset package is the only one in a .pkg choice notarization fails with:
"logFormatVersion": 1,
"jobId": "*",
"status": "Invalid",
"statusSummary": "Archive contains critical validation errors",
"statusCode": 4000,
"archiveFilename": "mypackage.pkg.zip",
"uploadDate": "2024-08-22T21:24:03.251Z",
"sha256": "*",
"ticketContents": null,
"issues": [
{
"severity": "error",
"code": null,
"path": "mypackage.pkg.zip",
"message": "Package mypackage.pkg.zip has no signed executables or bundles. No tickets can be generated.",
"docUrl": null,
"architecture": null
},
{
"severity": "warning",
"code": null,
"path": "mypackage.pkg.zip/mypackage.pkg",
"message": "b\"Invalid component package: mypackage_vstpreset Distribution file's value: #com.mycompany.mypackage.vstpreset.pkg\\n\"",
"docUrl": null,
"architecture": null
}
]
}
Not sure, but maybe its worth noting that the causing sub packge only generates a warning, but the parent package seems to escalate this into an error.
How can a non-binary sub package be included in a notarized parent package?
Any hints or thoughts are highly appreciated, Thanks!
Hello,I have been using Apple’s notarization services for some time, but for some reason, it has been failing for the last two days.
