wardo1254 Posted March 11, 2011 Share Posted March 11, 2011 I have everything in my laptop working under Snow Leopard, except Quartz-Extreme. I was able to get the proper resolution (1336x768) by using RadeonHD.kext. My Graphics card is a Ati Mobility Radeon HD 4250. Vendor: 0x1002 Device: 0x9712 Does anyone know how to get this card working properly?
