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 9.87

• Added new feature to delay the announcement of macOS software updates by up to 90 days after their release. Individual delays can be set for minor updates and upgrades that switch between operating system generations (for example from Sequoia to Tahoe). Affected pending notifications are automatically removed by macOS. The settings are available on the Issues pane.
• Added support for the evaluation of system background services for upcoming versions of macOS.
• When performing an application security check, the notarization field now shows more detailed information if applicable.
• Added a workaround for a problem where macOS could return invalid Internet links when showing details for a developer check of an application.
• Added a workaround for a problem where macOS could return raw technical data for the details of a packaging error when performing a developer check of an application.
• Fixed a problem where the button for performing a developer check was not shown for some application types.
• Fixed a rare exception status that could occur when mounting or unmounting SMB shares with invalid volume names while TinkerTool System was running.
• Added new features to support apps using the Mac Catalyst technology, i.e. running software for iPhone or iPad on Macintosh with Apple Silicon. For technical reasons, launching Mac Catalyst apps in different languages cannot be supported at the moment. Mac Catalyst apps are now accepted by the following functions:
• cleaning app components via the Uninstallation Assistant
• starting apps with special launch options
• computing a compatibility report
• performing a security check
• running bulk security checks via the Application Integrity feature
