TinkerTool is an application that gives you access to additional preference settings Apple has built into macOS. This allows to activate hidden features in the operating system and in some of the applications delivered with the system.

To further guarantee that the tool cannot change any part of your installation, but only gets access to your personal preference settings, the program puts itself under the restrictions of Apple's Application Sandbox. TinkerTool is the first application of its kind to use this innovative technology.

When you have defined your preferred set of “pro” preference settings, you can additionally export and import the settings, copying them to another user account or to a different computer. All settings which don't depend on the availability of third-party applications can be transferred.

Because TinkerTool only gives you access to features already built into macOS, its feature set varies greatly between different operating system versions. Please refer to the following table:

For older operating systems, please see the version overview page.
