I've encountered many problems with clean retail install, so i've tried with iAtkos Ml2 and it work... but not all, it's just a very basic system without

many features.


I've tried also different bootloaders, kexts and utility... without success.


Who can help me? I've darwindumper reports, are useful?



CPU: Intel Core i7-720QM da 1,6 GHz

GPU: ATI Mobility Radeon HD 5850 1024mb

RAM: 6 gb ddr3 1333mhz



What work:


Memorycard reader

2x USB 2.0

Keyboard & Trackpad

Not working:

Video (only with ATY_Init, without acceleration, many glitches and generic info in System Profiler [ex. only 7mb of memory recognized)

1x USB 3.0

WiFi (i'm planning to change it)



Here's a SystemInfo screen:


I hope there is a solution.


Thanks in advance to all. :D
