Is AppCleaner safe to use?

Ok, I read your previosu post but the thing is isn't cinebench a somewhat complex application since it does benchmarkinga and probably has different important components scattered throughout the system? What if it was a simpler app (for example, adium)? In that case wouldn't it do a far better job? It's not like I would use appcleaner to uninstall adobe photoshop...

Uninstalling complex applications is the only reason for AppCleaner's existence. Uninstalling simple ones is as easy as dragging them to the Trash. The preference files left behind by doing so are completely insignificant, but you can also delete those manually. You don't need AppCleaner to delete simple apps. It might be useful if it actually did delete complex apps effectively, but it doesn't.

In the example I gave, the 7115 remaining files I mentioned are all in the same folder that was created on my desktop when I unZipped the Cinebench download. I then dragged that folder to my Applications folder. It contained nothing that Cinebench's developer, Maxon, hadn't supplied with the application. All AppCleaner had to do was look for files in the same "Cinebench 11.5.29" folder I had dragged the application from, and it would have found every one of those files. It was too dumb to do that. It didn't show a single other file that was inside that folder, nor did it list the folder itself, despite its name.

It also completely overlooked (a) the "MAXON" folder in ~/Library/Preferences, which contains 46 files totaling 7.3 MB, all created by or installed with Cinebench, and (b) the "net.maxon.cinema4d" folder and enclosed file in ~/Library/Caches. I didn't even mention those in my previous post. I searched for them myself just now, exactly as I would have done if I'd decided to trash Cinebench before this thread appeared here.

In short, AppCleaner is completely ineffective doing the only task it even pretends to be useful for.

If you want to manually find the additional files installed with an app, one way is to check a file buried in the root directory called "install.log"

To do this, choose the 'Go' menu then 'Utilities' and open the Terminal application.

copy & paste this into the Terminal then replace 'NameOfApp' with the app name you want to search for:

cat /private/var/log/install.log | grep '/Library/' | grep -i 'NameOfApp'

You can also check for preferences left by the app:

ls -l /Library/Preferences | grep -i 'NameOfApp' && ls -l ~/Library/Preferences | grep -i 'NameOfApp'

may b as a newcomer u cannot really differentiate between associated files and those belonging elsewhere?
