Vermutlich wird die Grafikkarte Radeon HD 4870 das Problem sein.

Personally I think there should be a public record of how many Hackintosh users there are today and a count of how many people plan to build a Hackintosh in the next six months to a year. If that kind of number is made public and it's significant (maybe up to a million or more) it could possibly convince Apple to do something about it in a good way.
While I think that Apple doing the MSFT thing and trying to be the everything OS to all computer hardware is a bad thing Apple could make some custom hardware available to the GarageMac builders of the OSx86 community to reclaim as many legacy Mac cases as possible and recycle as many motherboards etc. as possible. Apple could go as far as to create a training program for authorized GarageMac building certificates where they could collect a fee from individual people helping other people re-build legacy desktop Macs on top of parts costs. Its clear that OSx86 isn't a trend that's likely to die off any time soon and more and more advanced users/builders keep adding to the ranks. It's high time Apple resolved itself to accept that they aren't serving their customers well at all in certain areas, but they can improve. They could even use information for something like this as marketing info. to help them build a line of more specialized computers. In any event if this is something you'd like to discuss further, agree with, disagree with reply to this and don't just be a drive-by post reader.
