Info updated on:

This program was designed for Mac users who wish to easily and quickly improve the performance of their systems. By working with this application you can find and remove user and system cache files, large or duplicated documents, unnecessary utilities, and many others.

K9-MacOptimizer provides you with a straightforward interface, simple-to-configure scan settings, and plenty of useful utilities. The main window of the app reveals the current status of your system (number of issues) and the level of improvement potential (in my case, it was high).

I like the fact that each of the integrated tools offers you individual cleaning options. For instance, Unused Languages utility allows you to choose which foreign dialect files (French, Italian, Turkish, etc.) should be permanently removed from your system.

Another advantage is the fact that you have access to an app uninstaller that not only removes programs from your Mac but it also lets you delete widgets and Preferences panes.

The one thing that bothers me about K9-MacOptimizer is that it lacks Pause and Resume options when it comes to scanning the system for unnecessary files.

As for the rest, the application works flawlessly and helps you improve the performance of your Mac within moments.
