Which kexts need to be removed for AMD 6750m in a MacBook Pro?

3 posts in this topic

Recommended Posts

As it's happening to a lot of people my notebook's discrete graphics is giving me all kind of issues.

 

Back in november i removed all ati/amd kexts (at least i think it was all of them) and the computer worked just fine with the intel graphics card.

So I gave the machine to my mother and she worked with it and had no troubles at all up until a week ago.
Problem is that somebody/somehow updated mavericks to 10.9.2 and the ati kexts got loaded again, so all the issues came back.

 

I removed all kexts again, the computer boots but it has several graphic glitches.

 

Anybody knows which exact kexts do I have to remove?

In other forums people talk about the AMDRadeonX2000 kext, but that one is not even there. There is a x3000 which i removed, plus a couple more, but I get the aforementioned glitches.

 

I'll appreciate any help (besides the hammering suggest i saw in another post).

 

Cheers

Mario
