    This thread is about compatibility of Polaris, Vega, & Navi graphics cards with the Mac Pro. This information is mostly reference for Mac Pro 5,1 (2010 & 2012) (or 4,1 -> 5,1 2009) users, and also Mac Pro 6,1 (2013) users who wish to install a GPU in an external enclosure. Note that it has not been officially confirmed yet if the Mac Pro 7,1 (2019) is compatible with non-Apple GPUs, but they will probably work both internally and as an eGPU via TB3.

    Please help others in the community by sharing your experiences with these cards. Also be aware that the behaviors of these cards may be different in a hackintosh and this thread is limited to the genuine Mac Pro only.

    Apple supports and recommends Polaris and Vega graphics cards for the Mac Pro 5,1 in macOS Mojave. Official list of recommended graphics cards: https://support.apple.com/en-us/HT208898

    These cards support all Metal feature sets in Mojave & Catalina, including family 2 version 1. However, none of these cards currently support the boot screen, FileVault, Apple Hardware Test, or FreeSync in MacOS on the Mac Pro 5,1. But they do support Recovery Mode and 5,1 firmware updates can be applied beginning with version 138.0.0.0.0. For Boot Camp without a boot screen see this thread: https://forums.macrumors.com/threads/how-to-boot-camp-without-a-boot-screen.2114788/

    Current Issues and Solutions for PC Graphics Cards

    -Some of these cards have trouble displaying over DisplayPort 1.2 or later. Solutions: Set your monitor to DisplayPort 1.1 mode or use a DisplayPort to HDMI adapter.

    -Some of these cards require more power than the two 6-pin GPU boost connections on the 5,1 logic board can adequately provide. Do not power the card from the logic board if it requires more than dual 6-pin or single 8-pin (single 8-pin must be connected to both 6-pin connectors). Solution: pixlas mod or separate power supply.

    -Some Vega graphics cards have high idle fan speed when installed inside the Mac Pro 5,1 with macOS 10.14.4 and previous. See Vega High Fan Speed Issue section below for more information. Solution: Install macOS 10.14.5 or higher.

    -eGPU connected over TB2 to Mac Pro 6,1 does not work. Solution: Patch available here.

    -These cards have a link speed of 2.5 GT/s (PCIe 1.1) rather than 5.0 GT/s (PCIe 2.0) when installed in cMP's slot 1 or 2. However, this does not reduce performance in realistic scenarios.
    Solution: Install firmware version 138.0.0.0.0 or later included with the macOS Mojave full installer. Note that some cards still incorrectly show 8.0 GT/s in System Information with the new firmware, but will still operate at 5.0 GT/s.

    Physical Compatibility Issues

    The following cards are too long to fit into the Mac Pro 5,1 without removing the PCIe case fan:

    -PowerColor Red Devil RX Vega 56 & 64
    -Sapphire Nitro+ RX Vega 56 & 64

    Andrew’s Mac Pro 5,1 Graphics Card Recommendations

    Here are my recommendations for cards that have a good balance of performance & power consumption and have good compatibility.

    Basic cards:

    MSI RX 560 AERO ITX (MSI Gaming Radeon RX 560 128-bit 4GB GDRR5)
    Pros: Recommended for Mojave by Apple for Mac Pro 5,1, low power consumption (60W), good for general purpose computing
    Cons: Not good for demanding 3D workloads or gaming
    Other considerations: 2 slot-width, requires no power cable

    Sapphire Pulse RX 560
    Pros: Low power consumption (90W), good for general purpose computing
    Cons: Not good for demanding 3D workloads or gaming
    Other considerations: 2 slot-width, single 6-pin power connector
    LuxMark luxball score (Mojave): ~5500

    Radeon Pro WX 4100
    Pros: Low power consumption (50W), good for 2D workloads (CAD)
    Cons: Not good for 3D workloads or gaming
    Other considerations: single slot width, requires no power cable

    Mid-level cards:

    Sapphire Pulse RX 580 8GB
    Pros: Recommended for Mojave by Apple for Mac Pro 5,1, quiet (zero RPM 'fan stop' at idle feature)
    Cons: Less powerful than Vega except in certain apps, relatively poor efficiency for performance (225W)
    Other considerations: Version 1 has single BIOS, version 2 has dual BIOS, single 8-pin power connector requires dual 6-pin to 8-pin cable, some users have reported that the card is slightly wider than 2 slots so the fans may interfere with a card installed in PCIe slot 2
    LuxMark luxball score (Mojave): ~15,000
    Additional info: Two early variants of this card were included with Apple's External Graphics Development Kit and Apple created a specific frame-buffer personality for them called Orinoco which provided enhanced compatibility. See this thread to modify your Pulse RX 580 to use the Orinoco frame-buffer.

    Higher-end cards:

    Sapphire Pulse RX Vega 56
    Pros: Powerful, very efficient for Vega (180W), quiet (zero RPM 'fan stop' at idle feature), low temperatures, readily accepts BIOS flashes
    Cons: 2.5 slot width blocks PCIe slot 2
    Other considerations: Dual 8-pin power connectors require Pixlas mod or separate PS.
    LuxMark luxball score (Mojave): ~28,000

    PowerColor Red Dragon RX Vega 56 (also sold as Dataland X-Serial RX Vega 56)
    Pros: Powerful, very efficient for Vega (180W), quiet (zero RPM 'fan stop' at idle feature), low temperatures, 2 slot width
    Cons: Users on other forums have reported that a different BIOS cannot be flashed to this card and the failed flash cannot be recovered.
    Other considerations: 8-pin + 6-pin power connectors require Pixlas mod or separate PS.
    LuxMark luxball score (Mojave): ~28,000

    Reference RX Vega 56 and 64
    Pros: Powerful, 2 slot width doesn't block PCIe slot 2, readily accepts BIOS flashes (e.g. 56 to 64)
    Cons: Fan can get loud, no zero RPM 'fan stop' at idle feature
    Other considerations: 8-pin + 8-pin power connectors require Pixlas mod or separate PS. Requires macOS 10.14.5 or higher to be free of high speed fan issue.
    LuxMark luxball score (Mojave): ~26,000-31,000

    High-end cards:

    Radeon VII
    Pros: Very powerful, 7nm design is more power efficient than predecessors, 2 slot width doesn't block PCIe slot 2
    Cons: Fans can get loud, open-air design may make case temperatures higher than a blower card
    Other considerations: Dual 8-pin power connectors require Pixlas mod or separate PS. Requires macOS 10.14.5 or higher.
    LuxMark luxball score (Mojave): ~51,000

    -----------------------------------------------------------------------------------------------------------

    The sections below are for reference and the issues discussed apply to macOS 10.14.4 & previous only

    Vega High Fan Speed Issue

    There is an issue where the fan(s) on some Vega cards spin constantly at high speed. Below are lists of cards that have been tested by myself and/or by others. You are encouraged to test additional cards. In High Sierra the fan(s) on cards in the "Issue not present" list still run at idle, but at low speed. In Mojave (beginning with beta build 18A353d) the fan(s) on those cards behave normally at idle (e.g. zero RPM), but a new issue has been introduced (see the second fan issue section below.) Note that this issue only applies to cards installed internally in a cMP. Note that the reference RX Vega 56 & 64 cards are available from most of the AMD partners and they have an AMD supplied cooler, PCB, and BIOS. Since those cards are identical, I've grouped them together. However, there are some cards that have a reference cooler, but do not have a reference PCB, such as the ASRock Phantom Gaming X.

    Issue present:
    -Reference RX Vega 56 & 64
    -Radeon Vega Frontier Edition
    -Radeon Pro WX 9100
    -XFX Double Edition RX Vega 56 & 64
    -Gigabyte RX Vega 56 & 64 Gaming OC
    -ASUS ROG Strix RX Vega 56 & 64
    -MSI RX Vega 56 & 64 Air Boost
    -PowerColor RX Vega 56 Nano Edition

    Issue not present:
    -Sapphire Pulse RX Vega 56 (model 11276-02)
    -PowerColor Red Dragon RX Vega 56 (also sold as Dataland X-Serial RX Vega 56)
    -PowerColor Red Devil RX Vega 56 Note (!): The Red Devil card is too long for the cMP unless the PCIe case fan is removed (not recommended).
    -Sapphire Nitro+ RX Vega 56 (model 11276-01) Note (!): The Nitro+ card is too long for the cMP unless the PCIe case fan is removed (not recommended).
    -Sapphire Nitro+ RX Vega 64 (model 11275-03) Note (!): The Nitro+ card is too long for the cMP unless the PCIe case fan is removed (not recommended).

    Unknown/untested:
    -Radeon Pro WX 8200
    -PowerColor Red Devil RX Vega 64 (Probably doesn't have fan issue since 56 version doesn't.)
    -ASUS AREZ Strix RX Vega 64
    -PowerColor Red Dragon RX Vega 64 (unreleased)(Probably doesn't have fan issue since 56 version doesn't.)
    -Sapphire Pulse RX Vega 64 (unreleased)(Probably doesn't have fan issue since 56 version doesn't.)
    -ASRock Phantom Gaming X Radeon RX Vega 56 & 64

    Solution for RX Vega 56 and 64 that have this issue: Use BIOS for non-affected card such as Sapphire Pulse or Nitro+, but only if your card model is known to readily accept a different BIOS. See BIOS compatibility section below. Note that an RX Vega BIOS cannot be flashed to a Frontier Edition, Radeon Pro WX or V series, or Radeon Instinct card.

    These combinations have been tested and appear to be working normally:
    -Reference RX Vega 56 with Sapphire Nitro+ RX Vega 56 secondary BIOS
    -Reference RX Vega 64 with Sapphire Nitro+ RX Vega 64 secondary BIOS

    Second fan issue

    In Mojave builds 18A353d through 18E226 the cards that don't have the high speed fan issue listed above have a new issue where the fan(s) spin up high under load as expected, but then fail to spin down. The fix for this is playing an H.265 (HEVC) video until the fans spin down. Also, occasionally after the computer boots the fan(s) will spin up, but playing a video will not cause them to return to normal (they will spin back up after the video is finished). The solution is to put the computer to sleep and then wake, or restart.

    RX Vega BIOS Compatibility

    There are 2 main variants of the RX Vega PCB, standard (full size) and nano. To be safe I recommend only flashing a nano card with a nano BIOS. This is because the VRMs are smaller and must not exceed 105 °C. Standard PCB bioses often have a VRM target temp of 115 °C or more. The standard card can be safely flashed with either another standard BIOS or a nano BIOS.

    Nano PCB:
    -Sapphire Pulse RX Vega 56 & 64
    -PowerColor Red Dragon RX Vega 56 (aka Dataland X-Serial RX Vega 56)
    -XFX Double Edition RX Vega 56 & 64
    -PowerColor RX Vega 56 Nano Edition

    Standard (full size) PCB:
    -Reference RX Vega 56 & 64
    -Gigabyte RX Vega 56 & 64 Gaming OC
    -ASUS ROG Strix RX Vega 56 & 64
    -ASUS AREZ Strix RX Vega 64
    -MSI RX Vega 56 & 64 Air Boost
    -PowerColor Red Devil RX Vega 56 & 64
    -Sapphire Nitro+ RX Vega 56 & 64
    -ASRock Phantom Gaming X Radeon RX Vega 56 & 64

    Warning (!): Some cards do not accept the BIOS from another card. The following cards do not readily accept another BIOS and the failed flash may not be recoverable:
    -XFX Double Edition RX Vega 56 & 64 (unknown if other version of same card can be flashed to it)
    -PowerColor Red Dragon RX Vega 56 & 64 (unknown if other version of same card can be flashed to it)
    -MSI Air Boost RX Vega 56 & 64 (other version of the same card can be flashed to it)

    The following cards are known to readily accept a different BIOS:
    -Reference RX Vega 56 & 64
    -Sapphire Pulse RX Vega 56

    To flash a different BIOS to your card it must be done using Command Prompt in Windows ran as an Administrator. The following commands will force flash a different BIOS:
    AtiFlash.exe -f -p 0 path-to-new-vbios.rom (with single card installed)
    Note: The program name changed to amdvbflash.exe with version 2.87. It appears atiflash starts the slot position count at the top. For example, if you had 2 cards installed with one in slot 3 that would be 0 and one installed in slot 1 that would be 1. So then if you wanted to flash the card in slot 1 with 2 cards installed you would type, "AtiFlash.exe -f -p 1 path-to-new-vbios.rom". If you accidentally flashed the wrong card then quickly flash it again with the correct bios before restarting the computer.

    If you put the new BIOS in the same directory then you just need to type the name of the new BIOS file (replace "path-to-new-vbios.rom" with the name of your rom). A new BIOS can be found online such as TechPowerUp’s VGA Bios Collection. Note that some BIOSes such as for the Pulse and Nitro+ are found under unverified uploads (the verified Nitro+ on their website is for the limited edition card and should not be used on a card that does not have 3 power connectors). Note that using a different BIOS on your card may void the manufacturer’s warranty (if you weren’t able to restore the original BIOS). Always backup your original BIOS using a program like GPU-Z.

    Make sure the BIOS supports your card's memory type (Samsung or Hynix) before attempting a flash. A BIOS that supports more than one memory type will autodetect the memory type.

    Some people feel an open-air cooled card BIOS should not be used on a blower cooled card due to concerns about temperature. It is up to you to monitor temperatures. The BIOSs have the same target temps for both types of cards so this concern may be unwarranted.

    If you flashed a BIOS to your card that didn’t work then shut down the computer and flip the BIOS switch on the card. Then start Windows and while the computer is still running flip the BIOS switch back. Then you can proceed to flash over the failed BIOS.

    "No fan issue" BIOS list (for macOS 10.14.4 and previous only):
    -Sapphire Pulse RX Vega 56 (nano PCB): 113-376XL-UO1 (primary), 113-376XL-U43 (secondary), 2nd version: 113-376XL-UO2 (primary), 113-376XL-U44 (secondary)

    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.

    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.

    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.
    --- Post Merged, Nov 2, 2017 ---
    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.

    I've reported these issues to Apple using Feedback Assistant.

    I installed the second beta (17C67b) today and the fan issue persists.

    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.
