besttech Posted March 3, 2013 Share Posted March 3, 2013 I have a lenovo g780 and after many problems able to install mac os mountain lion 10.8.2. Now i have graphic issues. I have screen resolution with champlist, but no acceleration. My specs: Intel Corei5 3210 8 GB Ram Intel HD4000 Graphics Atheros AR9285 Wifi Card (Changed from the dreaded BCM4313) I got this from VLC: Your Mac OpenGL acceleration is not supported on your Mac lacks Quartz Extreme acceleration, which is required for video output. It will still work, but much slower and with possibly with unexpected results. I don't know what to do. I tried many strings but it made mountain lion boot to a black screen. I Please Help.

WaldMeister Posted March 3, 2013 Share Posted March 3, 2013 Can you provide some hardware information? What strings did you use? DSDT present? etc.. Link to comment Share on other sites More sharing options...
besttech Posted March 3, 2013 Author Share Posted March 3, 2013 I have no DSDT The string I used was for the Lenovo G580. <key>device-properties</key> <string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string> I don't know what other hardware info you need.

WaldMeister Posted March 3, 2013 Share Posted March 3, 2013 Sorry, still had another topic in mind Thanks for the link. You could try other strings, there is a list somewhere, forgot the topic, so bumping. Link to comment Share on other sites More sharing options...
everdone Posted March 4, 2013 Share Posted March 4, 2013 Download ihackintosh's Extra folder from this post: http://www.insanelymac.com/forum/topic/280372-hd4000-full-acceleration-for-108-1075/ The string inside the org.chameleon.boot.plist in that folder should work. I have used that string on three different laptops with the 3210 cpu and video works correctly on all using that string. Link to comment Share on other sites More sharing options...
