Mac OS X is a very stable operating system that defragments the hard drive automatically, so it is not necessary to reformat the hard drive on a regular basis. However, MacBook Pro users may want to reformat their hard drives to fix disc problems, get rid of unused data or to sell the laptop. Disc Utility can completely erase the hard drive and install OS X from scratch or troubleshoot disc problems.

Users can select the "Erase" tab to completely erase the hard drive. They can choose from format and security options before they reformat the disc. Mac OS Extended (Journaled) is the ideal format option, since it prevents file corruption when the computer loses power. Once users have selected their format and security options, they can press "Erase" to erase the disc.

Once the disc is erased, users can see an OS X Utilities menu, which includes the option to reinstall OS X. Users running Lion, Mountain Lion, Mavericks or Yosemite do not have to use any install discs. Users running Snow Leopard and other earlier versions of OS X must use an install disc to reinstall OS X.

MacBook users can also reinstall OS X without erasing the hard drive. This reinstalls the operating system while preserving all files and data. Reinstalling the system can sometimes fix bugs in the operating system.

Users who want to fix disc problems can use the "First Aid" tab under Disc Utilities. This option can fix disc issues without a complete reformat.
