THX for the great Guide.
My System is:
Core i7-640m 2,8Ghz
NVIDIA Quadro NVS 3100M, 512MB
8GB 1333MHz DDR3 Dual Channel
256GB Samsung SSD
Dell Wireless 375 Bluetooth
Dell Wireless 5540 3G/HSDPA
Dell DW1510
Appstore, iCloud, iMessage and Facetime no problem
only Battery Bar is not 100% (it hangs sometimes) and sleep Mode didn´t go.
Is there a fix for these problems ?
