Hello,
I am a new Hazel user and I wanted to create a crule, which marks all apps that haven't been used for 2 months red. The result, however, was not what I expected, due to the fact, that the "last opened" dates are completely wrong and don't get updated when starting an app.
So Hazel is not to blame at all - however, as Hazel is working a lot with those dates I thought that maybe someone else here may have experienced similar behaviour or even fixed it.
Cheers!
