Mac: So you've upgraded to Mountain Lion, but you've found a few things that annoy you about the OS. Mountain Tweaks is a simple app that will fix those problems in just a few clicks.
Maybe you don't like the leather look of iCal and Address Book, or maybe you want to change the Notification Centre's background, or maybe you want to disable GateKeeper and install Mac apps from anywhere you see fit (not just the App Store). Mountain Tweaks follows in the footsteps of previously mentioned Lion Tweaks, giving you all the options to fix Mountain Lion's biggest annoyances.
Mountain Tweaks contains all the previous Lion-based toggles, as well as a few new ones for Mountain Lion. The developer notes that Mountain Tweaks will update with even more toggles as people discover them, so download it now and keep it updated!
Mountain Tweaks is a free download for Mac OS X Lion and Mountain Lion.
