I was afraid of that. If I want to run OSX with as little problems as possible I should install on a system with intel cpu. That makes sense. I'll probably just buy a mac when this comp dies. For all it's flaws as a desktop OS Linux is very stable. So baring any hardware failure I expect this system will last a long time. I don't need much a mac mini (or whatever apple will have similar to that) would do fine.

Thanks for all your help guys.
