Hello,
I didn’t see an OS X subforum, so I’ll just post this here.
This is the error that causes the screen on my Hackintosh (custom built Mac) to freeze and display a few rows of vertical red lines that stick to the mouse. I have the Nvidia Web Driver installed, and I’ve added the NVDA option to the kernel boot thing.
The OS X Default driver was toggled in the Nvidia Driver Manager during this error. From my experience, the error doesn’t seem to happen when using Nvidia Web Drivers enabled, but this might not be true.
The graphics card is an Gigabyte GTX 760-OC, with 2GB of VRAM. Here’s the System report for the card:
