If Apple just built what AppCleaner does directly into macOS, we wouldn’t have to worry about anything like that at all. In the meantime, we have to turn to a third party to help with something as essential as uninstalling an app completely.
Always thought how crazy it is that the functionality of this app never came built right into macOS itself. Until that happens, this really is a cornerstone app for anyone using macs.
Whatever educated guesses it’s making are pretty damn good then.
As a habit, I always give a quick scroll through all the files AppCleaner finds when I ask it to delete something and not once has it selected anything irrelevant. Been using it for many years now and the app’s performance has just been bulletproof for me in all that time.
If it works as well as it has for me, I would rather it go that extra mile and delete whatever crap it needs to delete rather than leaving vestigial files on my computer for apps I don’t want anymore.
