As a part of the build process, my build script calls 'xcrun altool --notarize-app' command to upload application package (inside disk image - DMG) for notarization. But approximately only 1 of 3-4 attempts complete successfully, as expected. All others lead to this output: [2020-02-07 14:30:48.602… (Show more)

Interesting. Clearly that shouldn’t crash )-: If you create a new user (using System Preferences > Users & Groups) and repeat this test as that user, does it work?

Secure Enclave when are keys deleted

Hello, I am using the secure enclave to generate an EC keypair. Now my question is, when are the keys deleted? Because when I uninstall my application and install it again, the key is still available. I can't find anything in the documentation that would explain how it should behave.
