I just got a 1050 Ti and got it working with hack #6 to enable NVRAM. On default OS X graphics, my Thunderbolt 2 audio device (UAD Apollo Twin) was working, but on NVIDIA it's not. At boot time, the white bar stops at about 80% for between 5 and 10 mins and sometimes eventually loads MacOS and sometimes doesn't. When it does, the screen resolution switches to a higher resolution, so it looks like it's switching from default graphics at 1024 x 768 to NVIDIA, but the background of the login screen is all garbled colours. Once I get to the desktop I get full resolution at 2460 x 1600 over DVI, but no Thunderbolt audio. This is the closest I've ever got after many reinstalls and eventually having to buy a new video card. I built this PC as a digital audio workstation so the Thunderbolt audio is vital. The audio device connected pretty much every time until I put the new video card in, so I feel like there's a connection. It's a Gigabyte Z170 Designare board with onboard Thunderbolt 2 over USB-C. Any ideas?
