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.

I have no DSDT
The string I used was for the Lenovo G580.


<key>device-properties</key>
<string>7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31</string>

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.

Download ihackintosh's Extra folder from this post: http://www.insanelym...n-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.

I know this is old, but I want to thank you for your find. This worked on my HP Pavilion g7-2247us Core i3-3310M HD4000 Graphics. LIFESAVER you are. :)
