Compute benchmarks in Geekbench 4 failing

Hi, I run a custom rig with an i7 6700k and a GTX 980 Ti. I run OS X as a hackintosh on it and have everything working beautifully with a vanilla install. I just purchased Geekbench 4 to run some benchmarks and compare my MBP to my desktop (and iPhone 7), the CPU benchmarks run fine on the hackintosh but the Compute benchmarks fail after 3 seconds. It completes the Sobel benchmark and then stops running benchmarks after starting the Histogram equalization benchmark. The only options available for Compute are OpenCL for api and Geforce GTX 980 Ti (running nvidia web drivers) for compute device.
The OS X drivers (opposed to nvidia's Web drivers) perform very poorly so i can't imagine that the driver is the reason, any ideas?

    This is a known issue when running the OpenCL benchmark with the NVIDIA web drivers. We are working with NVIDIA on a solution but do not have an estimate as to when a fix will be available.

    In the meantime let me know if you have any other questions and I'd be happy to help out.

    Thanks for the reply John, good to know its a known issue. I’ll play
    around with Apple’s drivers in the mean time (though again they tend to
    perform poorly for non-Apple cards :/, there are some hacks I can do to
    boost performance by masquerading as a genuine Apple card though I may play
    with that).

    Can’t wait for a fix, really want to benchmark my beast! (before and after
    I add another 980Ti in SLI config)

    I have the same issue with a gtx 970 in a MacPro5,1 - looks like geekbench can't find the type of card it is, you can see the console error on the first line...

    Guessing there's still no update on this issue?

    Same problem here. OpenCL Benchmark crashes on my MacPro5.1 12 Core, Nvidia 1080 GTX.

    Having the same issue - Geekbench 4 crashes when running Compute Benchmark -> OpenCL at the Histogram Equalization screen.

    I'm also running a hackintosh, GeForce GTX 1060 6GB (nvidia web driver version 378.05.05.15f01), Sierra v10.12.5 (16F73).

    This is getting tiresome. I have paid for this software and it does not work. No official response from Primate since October of 2016.

    What is the problem?

    Hi. Wish I'd found this thread before I paid for the software.

    Same problem here with a Hackintosh running an EVGA 1070 SC2 8GB (latest NVidia Web Drivers under 10.12.5) with an i7-7700K.

    Any idea when a fix will be produced? Thanks.

    Thank you for your patience. Geekbench 4.1.1 should resolve the issue with OpenCL benchmarks and recent NVIDIA GPUs. Please update and let me know if you continue to encounter issues running any of the compute benchmarks on NVIDIA cards.

    You can download Geekbench 4.1.1 for macOS from the following location:

    Facing same issue when running compute test on Ubuntu 16.04.2 with Geekbench 4.1.1. Nvidia 375.26. Video card is titanX Pascal

      Running Sobel
    [0825/133305:ERROR:src/geekbench/workload/compute_workload.cpp(114)] workload 203 failed validation

    There is an issue with the NVIDIA 375 drivers that causes Sobel to fail validation. Upgrading to newer drivers should fix the problem.
