From the Mac App Store, I installed CompuBench CL. The original install was about 60MB and then when I launched it the first time it indicated that it need to download something about 200MB to be able to connect to the results database. Sure I was leary, but it was from the Mac App Store (I wanted to use Unigine Valley, but the OS indicated that it is from an unidentified developer). So, I move the CompuBench app to the trash, but also wondered about what else it installed. Before trashing the program, I used the activity monitor to look at the list of open files/ports for this program and found in the Library/container folder called net.kishonti.osx.CompuBench. Using the terminal, I see that its still there and that in subfolders there is a copy of my desktop, downloads, pictures,mail, etc. I don't know if these are duplicates or links to the originals. I do know that when I do a screen capture the folder updates with the latest version. I'm using Terminal because I could not find any of this with Finder. In a data folders, I find 385MB in folders my Desktop, Documents, Downloads, Library, Movies, and Pictures. If I determine that these are all duplicates I'm going to delete this mess. I just don't know how these folders are getting new files, the original program is deleted. I'd like to delete the net.kishonti.osx.CompuBench, but am not sure if I should be making changes to the Library folder. To use Windows terminology, I want to roll back the changes ?!?#?#!! Anyone have suggestions ? Cheers. Thanks! > p.s. Okay, using the option+Go in Finder, I found the net.blah.blah.blah folder. .
