With its plethora of advanced options, TinkerTool System for Mac takes system optimization and customization to another level. This premium tool includes features ranging from the essential and system-saving to the highly specialized and obscure, all packed in a small app with an instantly familiar interface. It's a great app for geeks.

TinkerTool System for Mac asks for an administrator password prior to first launch, after which it lets you use either the full app five times (Evaluation Mode) or a limited version indefinitely (Demo Mode). Starting Evaluation Mode requires Internet connectivity. Once the app is up and running, you will be presented with an interface that is inspired by the Mac System Preferences app and that adjusts itself to only display settings, applicable to the hardware you're using. During our tests we were impressed by the "Emergency Tool," which adds a recovery mode to the operating system, triggered by holding down CMD+S during system startup. The automatic maintenance scripts, which let you choose between a daily, weekly, and monthly schedule to automatically delete temporary and unused files, thus reclaiming lost storage space, are also great. The entire process takes between ten seconds and a minute to complete.

TinkerTool System for Mac offers many features that power-users will find appealing. Whether you're setting up automatic maintenance or recovery mode on a Mac, or just like tweaking your system to its very core, this premium app's expansive features will grab your attention.

Editors' note: This is a review of the trial version of TinkerTool System for Mac 3.31.

Developer's Description

TinkerTool System 2 is a collection of system utility features assisting 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. All functions can be controlled by a single program which acts as general toolbox and First Aid assistant.
