Hi, this is my first post and I have a question.

So, I have been looking into making a computer for dual booting OSX.5.4 and Ubuntu. I want My Motherboard to be compatible with OSX.5.4. The board is the Asus P5N- D. So if you could tell me if that is compatible with 10.5.4 that would be Great. Thanks!

yes but it won't be a vanilla system so look at alternative look in the genius section at guide for gigabyte motherboards they have the best osx compatibility i know because I'm on the p5n-t and there is lan problems on both boards
