If you're not already a pro at using the command line, OnyX is a solid tool for conducting routine maintenance and tweaking the interface on your Mac. This free utility can help you with everything from checking SMART status on your disks to configuring the Dock, Finder, and Dashboard and Expose to your liking. The latest version adds several fixes to speed up the cleaning process.
Also this week, we have the latest version of Tinderbox, the idea-mapping tool that helps you connect disparate thoughts or information visually to keep you better organized. Our game this week is Battle for Wesnoth, the turn-based fantasy strategy game that offers a huge amount of content and excellent gameplay--even if the graphics are not quite to today's standards.
