I'm going to start with the basics for a second... built USB installer from retail app using a "mainstream" tool that I suppose isn't supposed to be mentioned here, but I'm sure it doesn't need to be. Lol.
Installed 10.8.3 update to that same USB installer, so I could avoid having to update during one of many install/mistake/re-install phases.
Computer is a Toshiba Qosmio X875-Q7390 (info here http://us.toshiba.co...870/X875-Q7390/
What is strange though, is I managed to get my nVidia GTX670M recognized in "About this MAC" without even trying. I ran the myHack (all options one at a time) no added kexts or tweaks yet, and all of the sudden my Graphics card shows up, with a system profile of "MacBook Pro 8,1" I will post a picture in a second. What I'm wondering, is it enough for OS X to be able to identify my card? What can I do now to ensure it will be fully supported with QE/CI assuming (and it seems like it isn't yet) that there is more to be done. Everything on my laptop is working fine OOB aside from Wi-Fi (intel wifi card isn't supported) Graphics (QE/CI), though I'm wondering if this theoretical quirk can count as progress, and sound (I use the Voodoo driver for that, so I'm not worried about it too much) everything else seems okay.
I did have to alter my installer though, removed the nVidia Resman kext from S/L/E and I make sure to do that on the system if and when I update.
I'm wondering if something in the myHack pack injected the correct information for my card into the drivers, and if the resman kext were in place before doing that again, if that would therefore also alter that kext to make my card fully supported.
I don't know. Thought I'd run it by you guys and see if I'm just dreaming, or if there is potential. Here's the screen shot as proof.http://bit.ly/10OXtZj
