macOS 13.3.1(a) causes a major crash when launching MicMac

Ventura version 13.3.1(a) causes a major crash in the latest version of MicMac. For some functions, I test the OS version with “<” or “>” operators associated with system.version.Majorversion/Minorversion, except the latest version includes an alphanumeric character “(a)”! which causes an OutOfBoundsException as soon as the app is launched.

Posting of a corrigendum (normally) on Monday at the latest.

The thread about this topic is a couple of lines below your thread.

And you app should handle all exceptions.

Not a major crash, a minor one because of exception not handled. you can display something more friendly or manage the exception.
