That's not to say that I run them on a regular basis like I should do, but whenever I find a new one I like to give it a try and see how it's going to work for me. Dare To Be Creative Ltd. recently released version 2.0 of MainMenu, a collection of Mac utilities that resides in your menu bar.
The US$10 application takes up very little real estate in your menu bar, displaying a small rounded square icon with a plus sign in the center (you can choose other icons as well). Clicking the icon unveils the menu seen at right.
Each of the clearly identified "buttons" leads to a submenu of functions designed to clean up or optimize some area of your Mac. Under the System submenu, for example, you can repair disk permissions (usually done with Disk Utility), run the daily, weekly, and monthly cron scripts for cleaning up log files, clean caches, rebuild the Launch Services database and the Spotlight Index, and update prebindings (not really necessary since OS X 10.4) and the Whatis and Locate databases.
You can also create your own batch files to run a number of the tasks at the same time, restart your Wi-Fi and flush your DNS cache, perform many user-related tasks, and more. When tasks complete, you get Growl notification.
MainMenu 2 is my Friday favorite because it puts a lot of maintenance mojo a click or two away; there's no need to use the CLI or dig into the Utilities folder, and yes, I am a very lazy person. What's your favorite Mac utility? Leave a comment!
