myMac system preferences
FORneXtSoft has announced myMac, a program that grants users access to certain hidden or unsupported system preferences in Mac OS X. In order to make changes with the software, users must normally be logged onto a Mac as an administrator. At times when changes cause the system to function improperly however, the administrator can undo them, or boot from the install CD and run a permissions repair.
myMac is compatible with Mac OS X 10.5 or higher, and is currently selling for $18.

so what..
First of all, all of these options are available to do with Leopard by either simply using the defaults command in the terminal or by just finding the pref panes that this app is trying to add. I say trying because the archive pref pane option as of 10.5.6 has been disabled. The only way to access those commands is through the CoreServices. All options in this app are easy to invoke after very quick and simple google searches. This is a nice front end app, so don't get me wrong, but almost $20 for something like this is a rip off.
