Our thanks to MacPaw for sponsoring MacStories this week with CleanMyMac 2. CleanMyMac is the simplest, fastest way to clean your Mac and remove unnecessary junk that your computer doesn’t need or has accumulated over time.

CleanMyMac can scan your Mac and find – besides unnecessary system files – files that you haven’t opened in a long time and that you likely don’t need anymore. CleanMyMac’s algorithms will find cache files, system and user logs, broken login items and preferences, old iOS software updates, hidden iPhoto files, and other large files that only waste space on your Mac; with an intuitive interface, the app will allow you to safely remove them and regain space without causing any issue with OS X (the app is ready for Mavericks).

In order to ensure that CleanMyMac would always remove the right files from OS X, MacPaw built a Safety Database for the app – a set of rules and exceptions that CleanMyMac uses to properly clean up junk files without doing any harm to the user’s system. The developers published a blog post on this feature, which you can read here.

CleanMyMac 2 is available at $39.95. A free trial is available at MacPaw’s website.
