Trying to play around with Secure Enclave Protected keychain operations in a Tauri-based MacOS app and running into issues. After much digging and trial and error, here is my understanding and where I'm at: To access these keychain related APIs, the app must be codesigned, and have the following entitlements: <key>com.apple.application-identifier</key> <string>XXXXXXXXXX.com.myorg.myapp</string> <key>com.apple.developer.team-identifier</key> <string>XXXXXXXXXX</string> <key>keychain-access-groups</key> <array> <string>XXXXXXXXXX.*</string> </array> Currently using a Development cert, generated from Xcode, not a paid account I had to install the intermediate cert from https://www.apple.com/certificateauthority/ XXXXXXXXXX is the "Team ID", which can be found on my Development cert under Details > "Organizational Unit" If I build the app and run it (without signing) I get code 34018 If I sign the app and try to run it, I am no longer able to boot it, with error: The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x12a60a130 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}} Not quite sure what is missing - any help is much appreciated.
