Well guys, i not find more the motherboard Asrock P4 915 Dual 478 for buy, then i would like know if someone know, which is a motherboard compatible with my processor and than it has a chipset 915 for be compatible with Mac OS X.

Someone know of some motherboard, and where i can buy and use with my processor?

I cant think of any. I use a msi 848p neo-v and it works perfect though. you can get that and a radeon 9600 for about the same price of any good 915 board. 40-50 bucks for the board and 60 for the video card.
