I have been waiting so long for this! I have already suggested CCleaner to all my Mac buddies. I would love to see some support for secure deletion, making custom entries, as WinApp2.ini suggested, as well as support for more software, such as Chrome, Opera, and Steam. I am sure all this is in the works as i type this. Piriform makes very stable, fast, and reliable software. I am glad to see them applying their talents to the Mac platform
Keep up the good work guys
