Reset Applications to Previous Versions on macOS
We use WireGuard to connect to our institute’s internal network as a VPN. A recent update of WireGuard on my Mac, however, caused all connection attempts to fail with an odd error. After searching a while for a solution (without success), I came to the conclusion that I had to downgrade the application to its previously installed version, which was working before.
This turned out to be more trivial than expected: Starting TimeMachine in the Applications directory in Finder allowed me to restore the old version of the WireGuard.app, and thus the old version of the tool.
I like this functionality a lot, actually, thus I am happy to share this experience with everybody who might have the same struggle that I had.
