TechTool Pro is a full-featured utility program containing options for testing and repair, maintenance (including disk defragmentation), and data recovery.
All it takes is one click of the mouse to perform a comprehensive suite of tests on your computer's hardware and attached drives. TechTool Pro does it all.
There is no need to purchase additional software to keep your computer performing at its best. In fact, it's so good that Apple includes a copy of its sibling, TechTool Deluxe, in its AppleCare Protection Plan.
