Sure it does, running GTX 970 on MacPro 5,1 right now with macOS 10.12 DP4 with web drivers and working fine
Incidentally, I'm not able to assign boot arguments to the nvram, which seemed like it might be the solution, and get this error:
claes2:~ claes$ sudo nvram boot-args="nvda_drv=1" nvram: Error setting variable - 'boot-args': (iokit/common) general error
Any reason this might be?
P.S. On legacy PBR, here are my nvram parameters according to terminal:
bootercfg (%00 fmm-computer-name claes prev-lang:kbd en:0 security-mode none Clover.KeepBackupLimit 0 SystemAudioVolumeDB %f2 SystemAudioVolume 0 LocationServicesEnabled %01 csr-active-config %03%00%00%00 Clover.NVRamDisk Yes
CSR Status (does this even matter?):
System Integrity Protection status: enabled (Custom Configuration). Configuration: Apple Internal: disabled Kext Signing: disabled Filesystem Protections: disabled Debugging Restrictions: enabled DTrace Restrictions: enabled NVRAM Protections: enabled BaseSystem Verification: enabled This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.
Any thoughts on why my installation won't load the web drivers?
Here's my boot.plist if it helps:
