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.
Added full support for macOS 10.14.4 and Safari 12.1.
Added new feature to let the application copy itself to the system Applications folder if desired when the program is launched from the virtual distribution disk.
