Don't install Mojave yet if you want Nvidia Web Driver cards to work. Hopefully that is clear.
but the other thing I've been getting nasty emails about is our "All Nvidia cards support Metal in Mojave" claim. People create a usb installer, fire up their 1080Ti or Titan Xp and are told they can't install due to there not being a metal card present. In fact, if you run the installer from an OS build with Web Driver running you won't see this. Why? because the minimal OS included in USB installer doesn't have driver for card to enable Metal, just our EFI running your screen, no METAL.
2 easy ways to fix this and run the install (which you don't want to do yet anyhow, see previous Blog posts)
1. Run from 10.13.6 with web Driver, or many other OS builds, as long as Web Driver running, and Metal enabled. It checks, sees a 5,1 with Metal card and you are off to the races.
2. Build a USB installer using dosdude's patcher. He offers a patcher that takes the "red tape" checks out. A previous version of his tool made problems for 3,1 mac Pros (and I got nasty emails about my 'borked' cards) but he has fixed that. And his new patch solves this install check too, though I haven't tried it myself. Others have and issued good reports. In fact, there are claims that his patch lets you keep using File Vault. (subject of next blog post)
In a few days when Nvidia releases the Mojave driver, I hope folks will come post their install results here.
And if you are penning a nasty, vitriolic email to MVC about this situation, instead send it to Tim Cook. He may be a superman doing wonderful things throughout the world, but he has made an error with this petty, vindictive stance toward Nvidia and the users of his products. AMD offered some bargain basement deals on their "Space Heater 1000" line of cards, but I think time and reality have shown this to be a bad deal for end users.
In a similar vein, I got a GREAT deal on some expired film last week. Incredible price break. Of course it doesn't work for my project, (or at all, actually) but it was REALLY CHEAP. Sometimes things are a bargain because they AREN'T a bargain . Tim? My people are waiting to take your call...
