Hello, Is there anything new on this? Thank you.

The extension has been in production for several months, it was working on Monterey, Big Sur, Catalina. It's a system extension. The entitlement: <key>Entitlements</key> <dict> <key>com.apple.developer.endpoint-security.client</key> <true/> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.application-identifier</key> <string>XXXXXXXXXX.AAA.BBBBBBBBB.CCCC.DDDDDDDDDDDD.EEEEEEEEE</string> <key>keychain-access-groups</key> <array> <string>XXXXXXXXXX.*</string> </array> <key>com.apple.developer.team-identifier</key> <string>XXXXXXXXXX</string> </dict>

Thank you for your answer, but I'm not sure this is exactly the same issue. The workaround doesn't seem to work on M1 Macs: "Workaround: Go to System Settings > Privacy & Security > Full Disk Access, select the security product, use the minus (-) button to remove, and then use the plus (+) button to re-add the affected security product. A system restart might be required to restore expected functionality."

The CMAKE_OSX_DEPLOYMENT_TARGET was set to 10.15. Problem solved.

Thank you Omarlkram. FileProvider seems to be the solution of the future, but it is not easy to find an example of use. I will try to use it.

I finally managed to fix the problem. I created a dummy application in Xcode embedding my sysext and I was able to recover the right entitlements. Thank you, Quinn, for putting me on the path to the solution. % codesign -d --entitlements :- /Applications/myApp.app Executable=/Applications/myApp.app/Contents/MacOS/kDrive ?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 keycom.apple.application-identifier/key stringTTTTTTTT.a.b.c.d/string keycom.apple.developer.system-extension.install/key true/ keycom.apple.developer.team-identifier/key stringTTTTTTTT/string /dict /plist % codesign -d --entitlements :- /Applications/myApp.app/Contents/Library/SystemExtensions/a.b.c.d.mySysExt.systemextension Executable=/Applications/myApp.app/Contents/Library/SystemExtensions/a.b.c.d.mySysExt.systemextension/Contents/MacOS/a.b.c.d.mySysExt ?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 keycom.apple.application-identifier/key stringTTTTTTTT.a.b.c.d.mySysExt/string keycom.apple.developer.endpoint-security.client/key true/ keycom.apple.developer.team-identifier/key stringTTTTTTTT/string /dict /plist

I noticed that, in the embedded.provisionprofile of the app, there is: keycom.apple.application-identifier/key stringTTTTTTTT.a.b.c.d/string But the bundle id of the app is "a.b.c.d" (without the team id TTTTTTTT), could it be the problem? Also, in the embedded.provisionprofile of the sysext there is: keycom.apple.application-identifier/key stringTTTTTTTT.a.b.c.d.mySysExt/string Is it OK?

Here are the console messages in case that helps. 06:39:23.937315+0200 amfid Requirements for restricted entitlements failed to validate, error -67050, requirements: 'private', error: (null) 06:39:23.937344+0200 amfid Restricted entitlements not validated, bailing out.

Here it is: FB9110597 (Finder badges refresh issue)

Problem solved. It was due to 2 different structures with the same name.
