Released in fall 2012, Mountain Tweaks 1.0.4 is an app for Mountain Lion users that is designed to ‘tweak’ your OS into super-usability. It’s a user-friendly, all-in-one solution that takes aim on the oft-annoying ‘upgrades’ in 10.8 that Apple has instituted. (Default iCloud saving, anyone?)

If you’ve noticed things about Mountain Lion that you wish you could change, but don’t want to dig into Terminal or attempt other one-off hacks, you’ll definitely want to give it a try. Using a simple “Yes/No” toggle, Mountain Tweaks highlights some of the most popular features in Mountain Lion that you may want to turn on or off.

Fun fact: Mountain Tweaks (and its predecessor, Lion Tweaks*) was developed by a 17-year-old from Norway. The app is free, but donations are encouraged, especially if you like what you see. Take a look at some of the available tweaks below (shortened list):
