TinkerTool System 9 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 macOS you are running.

All options available in the current situation are accessible via “panes”, very similar to the System Settings application. The features are controlled via a single window which allows you to use the application as a general toolbox and First Aid assistant.

This includes

• built-in maintenance features of macOS, usually not visible on the graphical user interface,
• extended file operations, not available in the macOS Finder,
• the possibility to access advanced system settings which are not visible in System Settings,
• graphical user interfaces for “pro” features for which Apple doesn’t provide any graphical interface in modern versions of macOS any longer,
• genuine and unique features of TinkerTool System, designed to resolve typical real-world problems of administrators and to fix the effects of certain defects (“bugs”) in the operating system,
• features to protect your privacy,
• an emergency tool to troubleshoot and repair macOS in cases where the normal user interface is no longer starting correctly or the user account of the system administrator has been damaged,
• functions to collect advanced information about the hardware, operating system, and applications.

What's New:

Release 9.85 (Build 251208)

• Added necessary changes to correctly support macOS 26.2.
• The assistant to select the time interval for querying the log database of macOS was significantly revised and its features have been simplified.
• After 5 years, the “modern” implementation of Time Machine is now considered the default. This will cause TinkerTool System to automatically offer the Time Machine pane instead of the Time Machine “X” pane in cases where Time Machine is failing. This policy change makes it possible to further diagnose such issues with the log feature.
• The documentation takes into account Apple’s changed procedure for downloading installation apps for macOS Tahoe.
• The documentation takes into account the modified behavior of the recovery system for macOS Tahoe.
