One of our apps (built with Xcode 26.1.1 and distributed via TestFlight) crashes upon launch on iOS 17 with Exception Type: EXC_BAD_ACCESS (SIGKILL) and Termination Reason: CODESIGNING 2 Invalid Page.
I have never seen this before. Any pointers?
On iOS 18 & 26 this does not happen btw.

I suddenly started to receive the following email with the error in it stating that my uploaded app is not available to be used in TestFlight:
ITMS-90886: 'Cannot be used with TestFlight because the signature for the bundle at “MyApp.app/Contents/PlugIns/MyAppWidgetExtension.appex” 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.'
It was all working fine and now I am not sure even where to start looking. Signing, provisioning and everything else is managed automatically.
The actual error:
pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (DeveloperID)”.
I'm trying to sign a program written with gfortran. The steps worked the last time (Mar 23) I built this code.
The steps to error:
a) xcrun notarytool store-credentials --apple-id "xxx" --team-id "yyy"
Giving Profile Name zzz and App-specific password
b) codesign --force --timestamp --options=runtime -s "Developer ID Application: My Name (yyy)" AppName
c) pkgbuild --root ROOT --identifier org.aaa.bbb --version "1.1.1" --sign "Developer ID installer: My Name (yyy)" AppName.pkg
ROOT contains the package contents
At this point I get the error
pkgbuild: error: Could not find appropriate signing identity for “Developer ID installer: My Name (yyy)”
Are there steps that have changed. Any suggestions?
Thanks, David
I am developing a macOS app that requires the Associated Domains entitlement. The app will be distributed as a custom app.
The app needs to be signed using Team A’s Developer ID Application certificate and packaged under Team A’s Team ID.
Team A has a secure signing and packaging setup, but they do not provide access to their Developer ID Application Identity (cert) or their provisioning profile.
I am part of Team B and have access to Team B’s Developer ID Application identity and provisioning profiles.
I am thinking of doing the following:
I create a provisioning profile under Team B that authorizes the Associated Domains entitlement.
I sign the app using Team B’s Developer ID Application identity, ensuring the required entitlements are included.
Then, I re-sign the app using Team A’s Developer ID Application identity, since Team A has also set up the same bundle ID with the Associated Domains entitlement and corresponding provisioning profile.
Questions:
Is this approach correct & does it have any drawback?
Will the double signing process work without issues, given that Team A has the required provisioning profile for the same bundle ID?
Are there better ways to handle this situation where signing must be done under Team A but access is limited?
Thanks!
When I first tried to sign my local unit test with the identity generated by Xcode, it failed because the intermediate certificate was missing. In that case, the error message explained that the trust chain could not be completed. But after installing the correct intermediate, codesign still fails, but no longer gives any explanation:
codesign -f -s '0EFE7E591A4E690842094B8EC5AFDFE059637D3C' build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST
build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST: replacing existing signature
build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST: errSecInternalComponent
It's the same error line "errSecInternalComponent". Is there a log somewhere that might explain what exactly is the error?

The Codesign command adds extended attributes to files that previously had no extended attributes.
In my case codesign add following extended attributes to text file in Frrameworks folder:
com.apple.cs.CodeDirectory
com.apple.cs.CodeRequirements
com.apple.cs.CodeRequirements-1
com.apple.cs.CodeSignature
Can I somehow prevent this behavior?
Thank you.
Hello,
I'm working on an app at work and we finally got to signing and notarizing the app. The app is successfully notarized and stapled, I packaged it in a .dmg using hdiutil and went ahead and notarized and stapled that as well.
Now I tried to move this app to another machine through various methods. But every time I download it from another machine, open and extract the contents of the dmg and attempt to open the app, I get the "Apple could not verify my app is free of malware that may harm your Mac or compromise your privacy.
When I check the extended attributes there's always the com.apple.quarantine attribute which from what I know, is the reason that this popup appears
I've tried uploading it to google drive, sending through slack, onedrive, even tried our AWS servers and last but not least, I tried our Azure servers (which is what we use for distribution of the windows version of our app). I tried uploading to Azure through CloudBerry (MSP360 now), and azure-cli defining the content-type as "application/octet-stream", the content-disposition as "attachment; filename=myApp.dmg", and content-cache-control as "no-transform". None of these worked
The only times where a download actually worked with no problems was when I downloaded through the terminal using curl, which obviously not a great solution especially that we're distributing to users who aren't exactly "tech savy"
I want the installation experience to be as smooth as other apps outside the App Store (i.e Discord, Slack, Firefox, Chrome etc....) but I've been stuck on this for more than a week with no luck.
Any help is greatly appreciated, and if you want me to clarify something further I'd be happy to do so
Hello
I have a qt, CMAKE app, non-xcode one till xcode start supporting cmake.
I have 3 apps, 2 basic ones and 1 very complex ones.
My complex one build/links/notarises/validates/deploys beautifly. I have tear in my eye when I see it build.
The other 2 apps explode and torment me for past 5 days. The build proves is 99% the same, the only thing that a little changes are info.plist and app name+ some minor changes.
Its absolutely bananas and I can't fix it, I'm running out of ideas so if any1 could sugged anything, I'll buy & ship you a beer.
Anyway, errors:

And here is my build script, its QT based application, I'm using macdeployqt + my own custom signing as the one from macdeployqt breaks on the complex app. (I will post it in next post as apparently there is 7k limit O.O)
I've tried to replace the @rpath/ to @executable_path but that has made a million new issues and I'm just lost.
The driver does not show up in the app settings after switching to “DriverKit USB Transport - VendorID”.
Previously, the app used “DriverKit USB Transport (development)” and everything worked as expected.
The entitlements looked like this:
<?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">

<array>
<dict>
<key>idVendor</key>
<string>*</string>
</dict>
</array>
</dict>
</plist>
I received approval to use “DriverKit USB Transport - VendorID”.
I updated the App ID configuration in the portal, removed all development entitlements, updated the provisioning profile, and edited the driver’s .entitlements as follows:
<?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">

The app installs on an iPad with an M processor, but the driver does not appear in the settings.

But I don’t quite understand what is going wrong. Any ideas?
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!
We are building an installer application to install a dext.
Building in Xcode, the installer app launches fine locally and installs the dext. We then try to sign it with the company Developer ID application certificate. However after doing so we cannot launch the application anymore as we get the following crash at launch:

Following the different help pages from Apple, the application seems to be correctly signed.
Looking at the Console, we are seeing the following message at launch: "Unsatisfied entitlements: com.apple.developer.system-extension.install, com.apple.developer.driverkit". However, the entitlement file I am using to sign the installer app contains those entitlements.
We are looking at different possible issues for days now and can't figure it out. Any advice or thought would be appreciated.

Hello,
I have a macOS app built with Flutter’s macOS target (native Xcode project). The app is unsigned (no Developer ID code signing / notarization). The .app bundle looks valid:
CFBundlePackageType = APPL
Unique CFBundleIdentifier
No LSUIElement or LSBackgroundOnly
Executable exists and is runnable
Placed at /Applications/MyApp.app (top-level), runs fine from Finder
However, it does not show up in Launchpad.
What I tried:
Remove quarantine:
xattr -dr com.apple.quarantine "/Applications/MyApp.app"
Force Launch Services registration:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f "/Applications/MyApp.app"
Rebuild LS caches:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
Reset Launchpad DB and restart Dock:
defaults write com.apple.dock ResetLaunchPad -bool true && killall Dock
Verified bundle structure/type:
mdls -name kMDItemContentType -name kMDItemKind "/Applications/MyApp.app" → shows com.apple.application-bundle / Application
Questions
Is code signing/notarization required for an app to appear in Launchpad (even if it runs from Finder)?
What additional conditions cause Launchpad to skip an otherwise valid, unsigned .app in /Applications?
Are there deeper Launch Services or Dock database checks I can run to diagnose why this specific app is excluded?
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?
I was working in Xcode with a free personal Team ID. I upgraded to the Dev Program and now have a paid Team ID. I used the same Apple ID for both. The paid Team ID shows up in developer.apple.com as associated with my Apple ID. However, Xcode is not using the paid Team ID in signing, it's stuck on my old personal Team ID. In addition, I'm getting provisioning errors (0xe8008015) when we try to run our app on an iPhone.
Anyone have any thoughts? I've scoured the forums and ChatGPT'd, Cursor'd, etc...all of the suggested fixes do not work. This almost seems like Apple needs to make my Apple ID associated with the paid Team ID or something, to start.
Thanks all.

I have been trying to package a FileMaker 18 runtime app* for Mac distribution for - oh - a year and a half on and off (the Windows version was packaged in an afternoon).
I succeeded - or thought I had - until I updated to Tahoe.
Now my packaging process does everything it did formerly (creates the DMG, etc.), but when opened, fails to see/load a third-party plugin (BaseElements.fmplugin).
Does anyone know why this should be?
I have attached 4 of my build files in the hope that someone can point me in the right direction.
Thanks in advance for any advice you may provide.
Regards,
L
*Claris deprecated the runtime feature years ago, but it still runs and is useful for proof of concept.
P.S. A contributor to an earlier query kindly suggested I go down the zip file or pkg installer route, rather than the DMG route. I tried doing as much but found both as susceptible to Mac spaghetti signage.

After upgrading the iOS system to 18.3.1, the APP crashed continuously when it was launched. The following log was seen in the device log:
Bootstrapping failed for <FBApplicationProcess: 0x72ad16b80; app<com.xxxx.yyyy>:> with error: <NSError: 0x300cd4d80; domain: RBSRequestErrorDomain; code: 5; "Launch failed."> {
NSUnderlyingError = <NSError: 0x300cd4ab0; domain: NSPOSIXErrorDomain; code: 85> {
NSLocalizedDescription = Launchd job spawn failed;
};
}
Our APP is in-house distribution
What are the possible causes? How can I solve it?
Hello, our app is non-sandboxed app, but we do want to support widget extension and safari extension. Those extensions require sandboxing. Is it possible to do this without sandboxing our app? Thank you!
I’ve been having problems with MacOS builds. I’m making a release Appstore build and uploading it to Testflight. However when running it instantly crashes, and report screen shows the following:
Current flow:
I sign all files in PlugIns/ (we have a number of .bundle), and I’ve tried combinations of signing with/without --entitlements, as well as with/without --deep.
After this I sign Frameworks/GameAssembly.dylib and Frameworks/UnityPlayer.dylib. Again, I’ve tried combinations of with/without --entitlements and --deep, also not signing them at all.
After signing PlugIns and frameworks, I sign the .app, also tried this with/without --deep (always with --entitlements).
Finally I make a .pkg and upload to Testflight.
It’s not the game, as I can make an enterprise version that runs fine.
We have some restricted entitlements, such as Apple Arcade.
Building from an M1 mac, and architecture is Universal (Intel + ARM).
Unity documentation says to use --deep, but Apple documentation highly recommend against it.
So basically, my question is, how and in what order should I sign the files?
Much obliged!
Xcode is prompting I enter a codesign login password when I am archiving my project. My password seems incorrect since there is no action after I enter my password and tap allow. what could be the problem?
