So finally i got my new notebook (Packard Bell LM85) working with OSX.
the problem is: my graphics card is an Radeon HD 6550 Mobility [1002:68c1] and identifies as HD 5650 Mobility and has also the same id... i tried the tutorial at page 1 but failed, osx keeps booting screen black, when i try to set resolution to 1366x786 via switchresx i doesnt gain effort... it just wants a reboot and then again screen is black. when i try my native res 1600x900 it has the same effect. so pls help me, how do i set switchresx up right...?? or wont this guide work for my card?
ps. sry for my bad english
Have you tried to put GraphicsMode=1600x900x32 in Boot.plist??
