Thank you, I will do that. It appears that 15.1 beta 1 and 15.1 beta 2 are no longer being signed by Apple, which is why the process fails. While that might make sense for the beta 1 it's really strange for beta 2.

To add some more details. When looking at the logs for com.apple.Virtualization.Installation I also see the following: amai: tss_submit_job: STATUS=94&MESSAGE=This device isn't eligible for the requested build.

Thank you for looking into this! Unfortunately I think we already have the newest Xcode with 14.2. Path to notarytool is /Applications/Xcode-14.2.app/Contents/Developer/usr/bin/notarytool It appears. Fortunately notarytool is not hard to re-implement, so making headway with a python version which should hopefully not crash then.
