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 a lenovo g780 with a core i5 processor. I have been trying to install mountain lion for a while now. Everything I tried I get still waiting for root device error.
So i finally tried to make a vanilla usb using http://www.insanelym...-for-beginners/

I still get still waiting for root device error. My bios is set to ahci. The only other mode is compatible and i tried that and it still didnt work. Help. Please

I installed Mac Os Lion on my lenovo b570 using a guide at http://www.<span sty...view=getnewpost

I used the retail version because iatkos l1 didnt really work for me. Right after the installation my trackpad was working fine. After I installed the dsdt provided by the guide the trackpad is not working and in the system preferences it says trackpad not found. I reinstalled mac os lion multiple tries trying to find the answer but i couldn't. I don't know why my trackpad doesn't work. I also tried reinstalling the voodoops2 controller and apple nub kext but that didnt help either.

The only way to navigate is by using a usb mouse.
can anyone help me?

Thanks
