To be honest I'm not sure. I don't use AMD graphics so not sure on the patching. However someone here will be able to help you with that, http://www.insanelym.../forum/174-ati/
Also look on the root of your pendrive. Do you see a folder named Extra? If so upload it. Assuming you're using Chameleon/Enoch to boot.
Sorry for the late reply. I came down with an illness a few weeks ago...
I also purchased a GTX 950 and installed it within my rig. However... I cannot find anything about that card working in Yosemite either. I have found some information about a "Web Driver" from nVidia, however after I installed it there was no difference in the display. Any ideas?
UPDATE: Never mind, I was able to get the graphics card working! I just needed to swap the Web Drivers around as the currently used driver XD So that's all taken care of. I tested with a 3D application and it works flawlessly.
However, now I need to get audio and my wifi working.
For audio, my motherboard came equipped with an Integrated ALC888S-VD.
As for the networking... That's more confusing to me. I think my Wifi is called "802.11 Wireless b/g/n PCI-E Mini card" (that's according to the manufacture's site). And my ethernet is a "10-Base-T PCI Realtek RTL8105E."
Do you have any suggestions for those components? Thanks for your help!
