Alexcoolstar Posted February 1, 2015 Share Posted February 1, 2015 Hey Forum... I succesfully installed Yosemite on my Lenovo G580 laptop. It seems to work fine, but i got a problem with the graphics. It only shows 4 mb of vram. Because of that is it very laggy, and i have tried a lot to enable the graphics, but nothing has worked. Intel Graphics HD4000 is intergraded in the laptop... Hope that somebody can help me... Thanks.

Allan Posted February 3, 2015 Share Posted February 3, 2015 This a cosmetic thing, doesn't means that your VRam is only 4MB. Link to comment https://www.insanelymac.com/forum/topic/304278-low-vram-issue-lenovo-g580hd4000/#findComment-2108325 Share on other sites More sharing options...

Sorry that im first replying now, but i had a problem with booting after the yosemite update. But i did the think in the link, but it didn't work for me. Is there any other way i can fix this problem? Dont know if it matters, but when i load kextstat the only "intel" kext which is being loaded is "AppleIntelFramebufferCapri"?

Allan Posted February 21, 2015 Share Posted February 21, 2015 For your QE/CI, you need AppleIntelFramebufferCapri, AGPM and AppleIntelHD4000Graphics loaded.
