Update from 4.12 to 4.14 breaks GPU rendering for both my Mac Pro machines
I have 2 Mac Pros (5,1 and 3,1) each with a GTX 1070. They have been running 4.12 (and 4.12.1). When I upgraded one to 4.14 recently on one of them, it completely broke GPU rendering. I tried clearing the DAZ3d application support and preferences, creating a new user account with fresh settings, and reinstalling Daz and Daz central. I even tried to downgrade to 4.12 by copying my version of 4.12 from my other Mac Pro which had not yet updated to 4.14. The issue persisted, and I was beginning to think it was my graphics card. But then I tried imaging the SSD with a clone of the SSD from the other Mac Pro, so they both have the exact same OS and Daz and CUDA and everything. This fixed the issue. So I assumed, the issue was something with other unknown variables associated with the install of the OS or DAZ. But then I tried to upgrade to 4.14, assuming it would work now, and the same issue came back again immediately. Again, the only solution was to re-image the hard drive. I tried on the other Mac Pro now, after making a backup of the hard drive for imaging in case it happened on that one too. After upgrading the other Mac Pro to 4.14, it did start having the exact same issues. So I can perfectly reproduce this issue every time on two computers, and all I have to do is install Daz 4.14, and it breaks my GPU rendering. It will always fall back to CPU now, and if I force it to use GPU, it will not render at all. It will continue to say "Preparing scene" and the progress bar resets itself over and over. And this is with an empty scene with a cube primitive. Any ideas?

Unfortunately Macs do not, as far as I am aware, have a sufficiently recent nVidia driver for the version of Iray in DS 4.14.x.x. All I can suggest is using a DS beta for 4.14.x.x and keeping your release build on 4.12.x.x, ort of course trying to use Bootcamp to run Windows for DS. The problem is that nVidia and Apple are thoroughly estranged and there will be no further support for nVidia hardware. Also, don't update to Big Sur as DS will not yet run under that version (not projected to change before the middle of next year).
Thanks. I will stay at 4.12. Why did they skip 4.13? Same reason there is no floor 13 on some elevators?
No one has said officially, but I would assume so. Either that or 4.13.x.x is a specil version for faking compromising images made available to a black-ops division.
is the 3,1 the one that broke? did you run a firmware to trick the APIs in the macOS to install and OS that was not sanctioned for that mac?
