    I installed the 10.13.2 beta build 17C60c on the cMP 5,1 today. A couple of things I've noticed:
    -The fan on the RX Vega graphics card seems to be running at full speed all the time. On 10.13 through 10.13.1 there would be a very short burst at start up and then it would be quiet.
    -In the root directory there is a Payloads folder with the following firmware updates "MultiUpdater" folder with file "MultiUpdater.efi.j137ap.im4m" and "USBCUpdater" folder with "HPMUtil.efi.j137ap.im4m" and "ThorUtil.efi.j137ap.im4m" files. There is also a Scripts folder in the root directory with those same files. Are they safe to delete?

    OpenGL issues appear to be resolved with RX Vega 56 GPU. Google Chrome now works well with hardware acceleration and WebGL enabled.

    Preview no longer crashes when attempting to crop a photo.

    The LuxMark v3.1 luxball score increased by 2531, from 20251 (on 10.13.1 beta build 17B25c) to 22782.

    Also, on previous builds sometimes a window would flash solid red when minimized or the section of the screen would be solid red where a crashed window was. So far that no longer occurs.

    Looks like drivers are improving for Vega cards!

    Thanks. This looks promising. How are you powering the card? dual mini 6pins to 8pins?

    If they don't fix the fan speed issue I may have to switch to the liquid cooled 64. Something to keep in mind if you haven't upgraded yet. Everything else so far appears to be perfect.

    may I enquire if you have tried a PRAM and SMC reset to see if that stops the fans from spinning all the time?

    I haven't tried that yet because that will reset SIP and I need it disabled to run Boot Champ. I'll see if I can boot into Recovery mode. On previous builds it would boot into it but only show a grey screen.

    Recovery mode works now. Resetting SMC and PRAM did not fix the fan speed issue.

    thanks for the update. What brand of card are you using? I am looking to buy a Sapphire Vega 54 and hope the fans get fixed in the next update.

    Little chance for this... In 10.13.1, at idle, reference vega frequency already throttle because of the heat.
    10.13.2 first beta brings better heat handling, and the card is far cooler now at idle: it allows higher frequencies (I got 15% geekbench compute score increase), at the detriment of fan speed and noise.

    Admittedly, this isn't very scientific, but I've had situations where my fans (RX480) kept going after startup. I learned that if I started a benchmark like 'Heaven', that in turn would trigger 'full fan mode' after a while. But once I exited Heaven and the card cooled down, the fans would go quiet as well.

    Can't say when it began or if it was fixed permanently, but if I hear the fans after reboot, I start Heaven and let it run for a bit. Then I exit and the fans go quiet. That "trick" has never failed me.

    Might be worth a shot.

    The fan should not be running that fast at idle. A geekbench benchmark does not run at idle. It puts a load on the card and in that scenario the fan should run faster.

    Thanks for the tip. I tried it. It didn't work.

    Sorry to hear that. My card is an MSI Gaming X, for what it's worth.

    Here's another issue. The Mac does not wake from sleep and the graphics card fan continues to run at full speed when it's sleeping.
    --- Post Merged, Nov 5, 2017 ---
    I've reported these issues to Apple using Feedback Assistant.

    I installed the second beta (17C67b) today and the fan issue persists.
    --- Post Merged, Nov 7, 2017 ---
    The Payloads folder in the root directory that the first beta created is now gone after the second beta update.

    On my MacPro with a RX-480 and a 5770 wake from sleep is definitely an issue. Started with 10.13.2 beta 2.

    Interesting, haven't had any issues with other VEGA 56, but haven't tried the Sapphire as well. Will buy one and report

    Are you using 10.13.2 beta? Since these are AMD reference cards they should all have the exact same vendor ID, device ID, subsystem vendor ID, and subsystem ID so MacOS should be treating them the same. I know those all match between the XFX and Sapphire cards. And since they are the same cards you don't have to buy another one. You should be able to flash the Sapphire BIOS onto one of your existing cards.

    Vendor ID: 0x1002

    Device ID: 0x687f

    Subsystem Vendor ID: 0x1002

    Subsystem ID: 0x6b76

    Revision ID: 0x00c3

    This is the BIOS on my card. I verified that with the GPU-Z app and it said this is it.

    It looks like you wouldn't actually have to flash the BIOS because according to Techpowerup, they have the exact same BIOS. Version 016.001.001.000.008766. Therefore, no difference at all between these cards.

    Same Bios: AMD RX Vega 56, Gigabyte RX Vega 56, MSI RX Vega 56, Powercolor RX Vega 56, XFX RX Vega 56

    There is another BIOS, but I've just verified that is the secondary BIOS. Version 016.001.001.000.008767: https://www.techpowerup.com/vgabios/194756/sapphire-rxvega56-8176-170730-1.

    The fan and sleep issues were not fixed in the 3rd beta (17C76a).

    It's hard to believe this will stay broken. For the iMac Pro... maybe they have a custom power controller firmware or something else custom.

    But for eGPUs... that would be using stock PCIe cards. So I hope we get fan and sleep fixes because Vega as a PCIe option looks pretty nice.

    Even I have no plan to go Vega at this moment. I still wish Apple can fix it to leave us more practically usable GPU option.

    However, the iMac Pro will not coming with the Vega chip at standard setting with the reference cooler. There is no need for the driver to handle that.

    And Apple officially only support the Sapphire PULSE RX580 8GB as the eGPU. I don’t think they really care if Vega can’t work properly as an eGPU.

    There have been a lot of hints out there for Apple and partners that Vega will be supported as an eGPU.

    RX580 is just the hardware that was out at the time of the beta eGPU program. It won't be the end of the supported hardware.

    It's even likely post-beta Apple will roll out official support for third party eGPU drivers.

    I am sure lots of eGPU work, just like my 1080Ti never ever officially supported by Apple. But it works flawlessly in my cMP now.

    However, it work doesn’t mean that’s supported. As long as it’s not officially supported by Apple, anything can happen.
