Regular readers know I like useful utilities without a price tag, or great utilities with an affordable price. One of the best ways to maintain your Mac is the trio of apps from Joel Barriere— OnyX, Maintenance, and Deeper; all free.
Here’s another free Mac utility to maintain OS X that’s a pretty good option for Mac newbies or those who want a little more control over OS X’s labyrinth of settings. It’s called MacMaintenance, and it’s a bit easier to use than Barriere’s trio, though not as comprehensive, and more of a Lite version.
Click on a tab at the top to reveal a few settings for the Finder, Dock, OS X Caches, System options, and Maintenance options.
Some of the Finder attributes are very useful, including the option to display the user Library folder (hidden in Lion and Mountain Lion), toggle the warning before emptying the trash, remove shadows on window screenshots, and a favorite– enable AirDrop over Ethernet on older Macs.
These kinds of functions are often worthwhile additions and don’t cost a dime. If you’ve never done much to enhance your Mac’s functionality, MacMaintenance is a good app to start, though Barriere’s trio of apps does more.
