Strange, I too updated my MP4,1-5,1 to High Sierra and then installed the nVidia web driver which recognised my stock GTX960 without any problem. Before installing the web driver I was running with my old GT120 and had a couple of crashes that seemed to be related to Apple stock driver. Maybe the GT120 is no longer properly supported?
Got a tip for us?

I won't be surprised. GT120 only exist on 4,1, and 4,1 is not officially supported. Just like one of the Wifi card is not supported anymore.
For firmware update you need EFI gpu, nothing else.
Support for the GPU is in the operating system. I've done all latest firmware updates with flashed R9 280X.

To update this point, SIP HAS TO BE TURNED OFF before you try a firmware update, otherwise once it runs (and fails), you’re 100% screwed and can’t ever do it again. This because you can’t get it working if you turn off SIP after a failed update, and you also can’t reinstall an OS from before SIP to bypass it. I’ll either have to go back to Sierra (if THAT’S even possible) to use my GTX 980, or I’ll have to just sell the card because it’s now worthless to me.
Maybe they found a way to make the driver read the existing cuda driver?? maybe?
SIP, well, protects the integrity of your system. When it senses an abnormal firmware update, it refuses to apply it. But changes are still made to your system by the utility before SIP kicks in, so when the utility is run with SIP off, it sees that those changes have already been made and it aborts, thinking that it’s already installed. A wipe back to 10.10 or earlier (which seems to be impossible, from Sierra or High Sierra, as I’ve now tested it) is required to bypass SIP and get the firmware update to run correctly.
Like an idiot, I did today's update and my system booted back into Windows for some reason and I'm having a real nightmare trying to get back into MacOS. Does anybody know if today's updated has knackered nVidia's driver support?

To run the High Sierra Supplemental Update in a cMP with Nvidia Web Drivers, the User MUST do this:

I can attest to the fact that IT IS A MUST DO!!!!!!!!

^^^^Thank you for the kind thoughts. However, I certainly can not take credit for this. MVC discovered the fix and posted it on his blog, not me. I merely re-posted it here to spread the word. And again, IMHO, MVC is a valuable asset to the Macintosh community whose absence from this forum is sorely missed.

I meant sharing whatever you know/read and sharing that to our MR community. So I credit you for that!

Not sure about that. 10.11.6 got an incremental update a couple of months ago which changed its build number. Nvidia provided the new driver the following day.
Having said that, I don't see the security update you're talking about - I'm on 10.12.6 myself.
Aha now I see! It's the security update for the ancient Public Beta for macOS Sierra...
Not sure the Nvidia web driver update is still available for that?
Cheers
Says the one who runs Mavericks!
10.10.5
WOW, you're a real good mimic.
Why join the Navy if I can be a Parrot!

No they don't, they supply drivers for the latest OS releases. But, if you look, the security update listed above is a Beta. Nvidia doesn't supply drivers for beta releases.
