GateKeeper detects malware

Some users reports me, that my application doesn’t start after some days. Today I get a logfile from one user. In this I see that Gatekeeper detected malware and stopped the start. Ir seems the problem started an update from macOS, but only in older version. With macOS 26 nobody reported problems.

The application is notarized and also the version in the store has the problem.

My question is now is some else has the problem, or has an idea which may caused it.

Thank you

Did you use SD Notary 2 for notarization?

Hello,

no, I use the notarization command from Apple within my build process.
