I have and


AMD-FX 4100 3,6ghz

4gb Ram

ATI Radeon hd 7700


anyhow I solved!

I managed to make it work by booting the pc with "KernelCache"=/amdfx GraphicsEnabler=Nosystem is stable, it recognize the 1gb of video ram and everything runs smooth :)

Hi.. i know its a few months later but this is the only relivent post i can find on the net.


basicly i have the same error.


my graphics card is a 

MSI Radeon HD 7770 

now, i would of taken my card out of my system and booted mac up to remove the files that one of you mentioned.

only i cant because my onboard graphics dont work because i dont have the required processor to do so.


so i think that only leaves me taking my drive out of my system, putting it into a caddy and removing them on another system.

only problem is, i can't do this as all my systems in my house are WINDOWS.


when i installed the mac os, i choose the 

Mac OS extended (JournaledFormat.

so obviously windows cant see this encryption.

i have tried several software to get around this problem, but none seem to work.


so before i go out and buy a brand new graphics card, i need to know is this definitely the problem ??



ps. i am a complete noob to apples mac os for now
