TinkerTool System Release 2

TinkerTool System 2TinkerTool System Release 2 is a collection of system utility features helping you in performing advanced administration tasks on Apple Macintosh computers. The application makes use of a self-adapting user interface which automatically adjusts to the computer model and to the version of Mac OS X you are running. All options available in the current situation are accessible via “panes”, very similar to the techniques you already know from the System Preferences application.

TinkerTool System Release 2 is no longer in development. Licenses are no longer in distribution.  They were available between June 26, 2009 and June 26, 2018. The application has been superseded by successor products.
