Just in case anyone finds that Oopsy suddenly stopped working after a system update (I’m on a Macbook Air M1), just a heads up: there’s no need to downgrade your OS, no need to restore the system from backup, no need to freak out. I did some of those things. But, all I needed to do was reinstall Homebrew. Back in action!
Y’alls probably knew all this, but just in case. (Meaning when the same thing happens to me in six months, I can come back here to search for the reminder)
