For most Mac users, the Mac maintains itself with little effort from the user. For awhile. Over time a number of things happen to OS X which may require a little user intervention. You know, maintenance. Mac websites have plenty of advertisements for utility apps which claim to clean your Mac so it performs better. For a price.
Most of what a Mac user needs to keep a Mac running in pristine condition can be found in a single free app which is cleverly entitled, Maintenance.
For most Macs that don’t have underlying problems with the disk drive or memory issues, Maintenance lets you do what your Mac might do overnight if you leave it plugged in and running, otherwise, one click gets the job done.
Maintenance has three basic areas of functionality– simple maintenance, cleaning, and rebuilding. And you get control over which ones are performed and when.
Maintenance performs one function which is already in Disk Utility (in the Utilities folder within the Applications folder)– repairing permissions. But it also executes various maintenance scripts built-in to OS X.
Perhaps the most important functions to run should your Mac act a little wonky are the Rebuild services. The Cleaning functions help to save disk space and remove a little of the cruft and clutter which collects on a Mac over time.
The same developer also publishers Onyx and Deeper utilities, both of which are also free. Onyx unlocks a few hidden features in OS X for the Mac’s Finder, Safari, Mail, iTunes, Spotlight, and the login window.
One of my favorites is Deeper, which also enablers a number of functions which Apple hides in OS X. All three apps are free to use, and give you one-click default restores, too.
