I got OSX Snow Leopard running on my studio 1555 (also tri-boot with win 7 and Unbuntu) but I couldn't get full resolution on my display. It's not really doable on most laptops because integrated graphics etc...

The way to go is to build a desktop and you can find tons of hardware lists online. So you won't have to deal with drivers and stuff. They're a pain. You can just get an install disc and install and be done with it.

If you're not building a PC there is still tons of info about which ISO's will work well with which computers. But if you don't have the right computer, it will be a pain. Drivers are hard to find because Mac only works with certain hardware but Windows doesn't make their own computers. They have to supply support for nearly EVERYTHING...

Good luck
