Hello, I need help from somebody, I recently bought a geforce GTX 285, it was meant to be for mac but I believe it is a pc card made to work on a mac. Here is the problem. The card works successfully under snow leopard. However when I installed Lion, the mac freezes during booting, the scrolling wheel appears frozen and stays like this. I did a clean installed, same results. My question is how can I get the card to work under Lion, I have installed the drivers from nvidia page, but did not help and I got same result. Maybe the rom of the card was old and I would have to put a new one but I don't know. The card is the geforce GTX 285 BFG version. Any help would be appreciated.
