I have a 6520 with Nvidia graphics and the non-intel wireless (realtek I think it is). I am having trouble getting the imbedded wireless to work still. Any ideas? I will be getting a 6420 next week, I will be setting that up for my Son. Not sure if it has Intel wireless or not. But I do know it has Intel graphics, so what kext works for that? I did my install for 10.7.2 with iFail L2 and selected VooDooHDA 2.7.3 audio drivers I believe. Not sure what else. ITs been a few weeks. I should have taken notes. I will be trying all of this on a 6320 soon too (that is for my Ex-wife and daughter). So any input on the Intel video adapter and the wireless can and would be helpful. If you have a link to the compatible wireless card to order if I need it for the 6420 that would also be helpful. I seem to remember that the 6320 also has the realtek wireless card. I just can't figure out which kext I actually need. iMacinTosh - 12,2, core i5 Quad 2400, i7-3770K Quad core, 16 32 Gigs Crucial 1600 memory, PNY Nvidia 430 GT 2G DDR5, SOYO 20 LG 24 HD Monitor, HDs in an Antec 300 CM 922 HAF case
