As long a I'm asking display questions it there a ultramon like utility for mac ?

I can't think of anything off the top of my head that matches the features they list (never used the program) although a lot of that is built into the OS (mirroring, multi-display screen savers, more than 10 monitor support, etc.). If there is something in particular you want have you tried searching www.versiontracker.com?
