Recently I have installed Mac OS X Yosemite 10.10.1 (Niresh's Version) and everything is working great....Until I have noticed that my mouse movements were glitchy, web browsers were malfunctioning. I have also realized that Yosemite does not recognize my graphics card. I have installed the latest NVIDIA web and CUDA drivers, but none of them work. I have even tried the boot flag nvda_drv=1 same thing. Is there any fix to what seems to be my nightmare? Do I just have to buy a new graphics card? Here are by PC specs CPU: AMD Athlon x4 860k Motherboard: ASUS A88XM-A RAM: 8GB Crucial Ballistix Sport GPU: EVGA GTX 750 ti Thanks for your help!!!
