Mountain Lion on eMachines E732z

Hey guys i was wondering if you guys could help me set up Mountain Lion on my eMachines e732z.

I have installed Lion 10.7 on it before but got stuck on the driver section and before i attempt another installation i would like to gather all the drivers beforehand.

What surprised me was that i couldn't get my Intel HD 3000 graphics to work. I still remember that it got recognized in system info however i could never set it to its native resolution, even with the boot command forcing it to.


Anyways heres the specification, surprisingly similar to Acer Aspire 5742, which may have more support than my infamous laptop.

Tried to install it

Eventually gave up, The Intel HD graphics are first gen and theres no kext for it

wireless theres no kext either

sound may have a working kext but most likely requires more than a kext to make it work


No point
