What's New

Version 3.4:

  • By request of many users, panes of TinkerTool 5 can now be integrated into the application (TinkerTool 5.3 or later is required). As a result, support for 32-bit computers had to be removed. Users of such systems should keep version 3.31.
  • Corrected a problem where information about the system enclosure was not displayed correctly as part of the system management overview.


  • OS X 10.6 or later
