TinkerTool is feature packed software, which gives you access to the additional preference settings that Apple has built into Mac OS X.

The software will allow you to activate hidden features within the OS and also in some of the applications that are bundled with OS X.

You don't have to worry about damaging your entire system, as TinkerTool will ensure that preference changes will only affect the current user (No Administrative privileges are required).

Please Note: OS X 10.9 or later is required.
