Hey

I have a system with i5 3570k, Radeon 7970, Z77 Extreme4 ASRock MB.

I've successfully installed Mountain Lion, using GraphicsEnabler=No on Chimera.

Because obviously, the 7970 is unsupported

Instead, I want to use my CPU's HD4000 Graphics.

So, I updated Chimera... No luck. I can't change my screen resolution.

So;

My monitor is plugged into my 7970, because it needs a Dual Link DVI.

I updated Chimera. Also, it said you have to change a setting in your BIOS for Integrated Graphics Memory Size? On my board, I can only see DVMT Size. What is going on here?

I can't boot without GraphicsEnabler=No.

Please help!!!

Thanks a lot... This website is golden!

unplug your 7970 ？
Not sure if discrete card and integrated card both exist, which one will work
But I recommend up till now, since 7970 is not supported, you unplug it and use your integrated HD4000

But will it work if I still have my monitor plugged into my 7970?

unplun everything connected to 7970
use your integrated HD4000 only

My monitor runs on a Dual Link DVI and my motherboard doesn't have that output.

if that's true, as far as I know, only HD4000 will work.
Since you don't have an output, it's sad you won't be able to run your hack
Unless you change your connector so that you motherboard's output connector can connect to your monitor

Best Graphic card that has no problem at all is 8800GT (I have XFX Alpha Dog Edition) .. Cheap 'n' Classic but Charming! (bought it from a french website with only 35Euros ) Powerful stuff don't impress MAC it seems...
it's the only graphic card I tried and it works perfectly.(just use graphicsenabler=yes) no need to modify any kext or add ID or anything... (Mountain Lion 10.8.2)
but the specs you have call for an extra more powerful GC. look for best supported GC out there then buy it Good Luck...

get an hdmi to dvi adapter for, a bit more for a dual link one vs like 2 bucks for single, but cheaper than a new card. I could not in good conscious recommend buying an 8800gt, but would be OK as a second hand card. I beg to differ that powerful stuff does impress OSX just fine. Been playing Boarderlands 2 in a Wineskin wrapper with all settings maxed and it's gorgeous. If I also enable max physx via CPU rendering by editing config.ini, it will get a noticeable stutter every so often, but 8800gt could act as a dedicated physx card if I hadn't gave mine away a few years ago.
