CleanMyMac, an application for Mac maintenance that aims to find and clean data from Mac computers to make more free space available, has received an uptate. First released in 2009, the app has since become a well-known and highly regarded Mac cleaning tool. CleanMyMac 2 has just been released with some new updates, and is free for current users.

Among some of the new updates, CleanMyMac 2 comes with an auto-cleanup function that looks for unneeded files and cleans them up by asking you whether or not they can be deleted before actually doing so. It also removes old logs and caches, deletes master copies of previously edited photos in iPhoto, and can uninstall apps that are no longer being used.

If you aren’t a current user, a trial version of CleanMyMac 2 is available and allows you to remove up to 500 MB of stuff for free. Until March 8, the new version is available for new users at a cost of $19.95 for a single Mac license. CleanMyMac 2 requires OS X 10.7.5 or later and takes up 50 MB of disk space. If your Mac doesn’t meet these qualifications, the previous version of CleanMyMac will also work.
