Mac Pro 5,1 Metal Graphics Card for Mojave?

Apple recommends certain AMD Polaris graphics cards for the Mac Pro 5,1 to run Mojave including the "MSI Gaming Radeon RX 560 and Sapphire Radeon PULSE RX 580" as stated on the public beta FAQ page. However, they have also been directing people to the eGPU support page, which includes AMD Vega graphics cards as well. Both Apple and AMD have some RX Vega 56 cards installed in their 5,1 testing machines according to an engineer I spoke with so they are supporting those cards as well, but to properly run them they require additional power beyond the boost connections on the logic board (such as pixlas mod or separate power supply).

Beyond that we have very limited information from Apple regarding this as it is still in beta stage. It is unknown if they are going to enable boot screens on these new cards via a firmware update. If they don't then FileVault, Boot Camp, and Apple Hardware Test will no longer be supported on these machines.

Install macOS 10.14 Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012) - Apple Support

If your Mac Pro 42 lb silver tower meets the requirements in every other way, and has been updated to 10.13.6, you can "try out" Mojave with just a standard graphics card by using an unsupported hobbyist hack. I tried it out with a regular Mac-firmware 5770 card on my Mac Pro 2009 updated to 5,1 firmware. I did NOT apply any additional offered features except to bypass the Apple lock against installation without the "proper" graphics card. This version does NOT require you to disable System Integrity Protection for this case.

I found that there were a few very small artifacts using "light" mode, none using "dark" mode.

When I used OpenGL ExtensionsViewer, it reported I had only "Apple Software Renderer" in place, and NO Metal-capable graphics card (rather as expected with only a 5770). My take-away was that this was probably not suitable for Video editing (but it played web Videos just fine). Over a few days I found it perfectly acceptable for web Browsing, and not noticeably slow or unstable in any way.

The other thing I learned was that this install was very straightforward if you followed dosdude's instructions, and might be good way to install if you had an unusual non-Mac-firmware graphics card you wanted to use. Using this method, you could get the Mojave software settled into place, then wrestle with the graphics card issues.

Use extreme caution is acquiring any cards that appear to be Metal-2 compatible.

Users found that, when installing High Sierra, the card had to self-identify as OpenCL capable BEFORE its driver was loaded. That effectively limited users to genuine Mac-firmware cards. (this was determined by reading the Installer Log of a failed Install. The card had to say "I am OpenCL capable", but PC-only cards did not say that.)

If the same approach is used for Mojave, many PC-only cards, although Metal-2 capable once their drivers are loaded, will not work.

Hello

I want upgrade my GPU for Mojave, now I have Radeon HD5770 ( Mac Pro 5.1 2x3,33 Ghz )

which card I should user ? Can I use an AMD R9 290 or ( X ) ?

Where I can find a list with GPU compatibility ?

Thanks Max

The reason you are not seeing Mojave information is because it's in beta and can't be publicly discussed.

It's been about 6 weeks since this was first posted. Can anyone recommend a graphics card at a good price? Nothing fancy, just want to run Mojave on mid 2010 Mac Pro 5,1.

If you install using a MacBook Pro said with an external drive, you can run it even using the HD 5770. Seems to work except those required graphic card ...

Officially there are no new video cards for the Mac Pro 2010 that you can buy.

If your willing to get a now quite old secondhand card the best two options are an EVGA Mac edition GTX-680 or a Radeon HD 7950 Mac edition. Beware in both cases of PC edition cards of the same model.

Unofficially some Nvidia and AMD cards can be flashed with Mac firmware. This adds a lot to the cost of these cards.

I personally have an AMD Radeon HD 7950 Mac Edition (genuine) and it will run Mojave. Although possibly due to an Apple bug or Apple hostility the App store did not recognise this as being suitable even though it is a genuine Metal compatible card as reported in High Sierra System Information.

I had to download the Mojave installer on a MacBook Pro and copy it to the Mac Pro to get round this.

Apple claim Mojave support for Macs "along with 2010 and 2012 Mac Pro models with recommended Metal-capable graphics cards." Nowhere have I seen Apple list their 'recommended' Metal-capable cards. As mentioned even a universally agreed best choice of a Radeon HD 7950 Mac Edition card was being blocked by Apple in the App store if not in the installer itself. I think this 'effort' by Apple is summed up nicely as below.

It should be noted even once you have installed Mojave Apple are still artificially disabling both HDMI Audio Support and 30-bit aka Deep Color support on the Mac Pro. Both features work in Windows 10 via Boot Camp!

Here is a link to the eBay seller I used to obtain my flashed GTX680. He has a number of cards that are supported. He is also quick to reply with any questions you have.
