We're aware of the issue with third-party GPUs under OS X. We're
able to reproduce the issue internally and it appears the cause is
an interaction between the OS X OpenCL runtime and the NVIDIA
drivers. We have filed bug reports with Apple and NVIDIA and are
currently waiting for a response.
Oh thank you so much for deleting the long account I wrote before I realised I wasn't logged in. Cut to the chase. In W10 Pro the latest NVIDIA driver for my Quadro 600s, Quadro 5000, and GTX 1060 6GB was 18.104.22.16833 2016/12/11 which (as it happens) I installed yesterday after I had already run GB 4.0.0 successfully with the previous one: 21.21.13 7290 (2016/09/16). Then I upgraded some other machines (Z600s with X5660s, Z800 with X5675s and X5690s). Today I had some working in GB 4.0.4 and some not. Just now I have rolled back some of those updates and all is well (see data uploaded for GTX 1060 of Z800 with X5690s). "7633" is what GeForce Experience wants you to have. "7290" is the "latest driver" as far as W10 upgrading is concerned. I will now prove my case by rolling back the driver and this Z800 with X5675s and doing the compute thing on its Quadro 5000. Assuming it works, I would like to be rewarded with a "Compute Results Search" that works on the GPU, not the CPU. Both is better, of course. The bottom line?: On Win 10 machines check your driver.
