Hi @tiffle,
This is a good idea but I don't have a cmd-, trigger.
Even if I did, though, this wouldn't explain the issue with KM freezing up after I interact with the security prompt. This seems to be some weird case of KM interacting with macOS's increasingly annoying security infrastructure.
By the way, at least one other user has seen this problem: KM 11 issue: access data from other apps - #9 by Airy
it just that they got lucky and the issue vanished after a OS update.
I appreciate the feedback & ideas.
