Onyx is a great piece of software that should be on every Mac computer.  It serves as a cleanup/maintenance utility, and it has some additional features that allow you to customize settings in your Mac beyond what is usually available.  The main things I use Onyx for are to run the periodic Mac cleanup scripts, check my hard drive’s S.M.A.R.T. status (which could warn you of impending hard drive failure), and periodically clear out the various caches of system data.  Onyx can do so much more as well.  I used Onyx to tweak the appearance preferences of my windows.  For instance, all the scrollbars in my windows have both up/down arrows at both ends.  Onyx allows you to make tweaks like this without having to know the cryptic Terminal command.  Click the link after the jump to get Onyx now.

Here is the website for Onyx again.  Note that there is a different version of Onyx for each vesion of Mac OS X (Leopard, Tiger, Panther, Jaguar).
