I have it inside my home folder: /Users/“username”/Applications/Bear.app and I also tried using /Users/“username”/Bear2/Bear.app. (i.e. not under /Applications)
Was using ~ to indicate my home folder…
Yes, I have tried to restart it from the locations mentioned.
I’m a little puzzled about the problem you are experiencing but I have found a workaround suggested on the site of an app that uses the same updater library.
Go to Applications and find Bear.
Make a copy of Bear to Desktop.
Move the copy of Bear in Applications to the Trash.
Move the copy of Bear from Desktop to Applications.
Launch Bear again and try “Check for Retrospect Updates…”
