The larger fan tends to block the adjacent PCI slot, making it hard to recommend for its minimal performance gains. Recently in Mojave, updates have enabled hardware acceleration for video codecs on the RX You can read about it here and find full instructions to Activate AMD hardware acceleration.
Thanks for Martin L. MacRumors forum-goers report that following Radeons are supported in Many of the cards can be flashed to different bios. The Vega 56 can be flashed to use the Vega 64 firmware to increase the performance. It isn't quite as fast as running a Vega 64, but it is close. That said, without a power supply modification, many users self-included experienced crashing when the GPU hit intensive loads and required reflashing it to Vega 56 Firmware.
It requires Windows Several MacRumors forum members have found that Mac Pro 3. See the full list here. More recently, the 3. Both Catalina and Mojave are supported. With the advent of Apple published an official list but did not list all compatible GPUs for Mojave. Currently, NVidia blames Apple for not approving its drivers for Mojave. That said, without Mojave support for off-the-self NVidia cards, this severely limits the impact and does not currently have drivers for the macOS.
They will show up as a generic VGA output. NVidia driver installation is a little more tricky than one would expect. First off NVidia does not list what cards are currently supported on its web pages.

Secondly, you need to download the correct version of the drivers for whatever version of Mac OS you have. TonyMacX86 forums do an excellent job of direct linking to the NVidia installers for driver version number by OS version. Currently, Seeing the above mess of information and the corresponding versions of drivers, Benjamin Dobell wrote a CLI utility to install the Mac NVidia drivers that work for your system, as described as "This script installs the best not necessarily the latest official NVidia web drivers for your system.
The cards do work, but the turn-around times are long, communication infrequent, and the prices are high, but they are legitimate, with many testimonials floating around message boards from longtime members that they do indeed work as promised. Note: Dave of MacVidCards notes he did contribute on previous AMD card hacks and did not get paid for his work on this I'd rather not weigh too much on the ethics on it, but software developers do deserve compensation, and depending on the actual work performed on the EFI ROM, it may very well be truly custom.
I suggest googling for them, and let you be the judge if its worth the cost. Note: I have to note that, after reading the previous statement, Dave of MacVidCards reached out to me and also corrected on errors found on this page. So if nothing else, my experience with MacVidCards has been fair in my limited dealings with them considering my hesitation in recommending them.

There isn't a "best card" for any computer, rather how much money you're willing to spend and if the money could be better spent elsewhere. This is an arbitrary metric as even a 3. I'd argue buying a 4.
The next question is, do you want an EFI native card? There are few cards that support the EFI boot screen, and they are all older generation cards. Most users elect to hold onto an older card as a backup, for the EFI screen. I personally have a GT in my Mac Pro at all times for this reason.

Many users keep a 2nd video card as a "just in case" and choose not to run any backup GPUs. Lastly, there's Mojave to contend with. However, neither have EFI support. Some readers have reported they are able to run high-power requirement GPUs off their internal power supply. These are likely required to power your GPU. Example, a GPU that has a 6 pin power port and an 8 pin power port would require one of each cable.
I wrote two guides blog.
I tested a GeForce Hackintosh vs. The secret is simply getting a single card slot mount and replacing the dual height on the card and using the fourth slot. It's not perfect as it blocks off SATA ports. Many modern graphics cards have HDMI and thus capable of outputting audio. There's a very long thread of intrepid hackers at Mac Rumors. This is a case-by-case issue and may or may not be an issue for various users. The Mac Pros can support many more cards than listed here. NewerTech and Sonnet are reliable. Not all cards are equal, some are more performant, in the case of USB 3.
Also, some non-listed cards have issues. The only way to turn off my Mac Pro was to hold down the power key forcibly.
I've elected not to include USB 2. Note: This is not to be taken as a complete list, but rather a list of known working cards that users have confirmed. If you know of a card that's supported by macOS, please reach out to me. Currently, the list is expanding, non-bootable cards will be listed as such. Known bootable cards will be listed as such.
If no notes appear, it's because I haven't researched this yet. In the unlikeliest turn of events, Thunderbolt has landed on the cMac Pro PCIe Thunderbolt cards were exclusively for PCs that have compatible motherboards with specialized chipsets, generally requiring a pass-through jumper connection. The original speculation started at eGPU. The only way currently to use a Thunderbolt 3 card is to cold-boot to Windows Initialize the Thunderbolt 3 card with the proper drivers installed, then reboot to Mac OS, where the Thunderbolt 3 card will remain Initialized.
Also, only some Thunderbolt 3 devices work, such as audio interfaces. Right now, it isn't very viable for all but tinkerers to purchase a Thunderbolt card, but this may change. As notable progress unfolds, this section will be updated to reflect it. This isn't recommended as the computer will not wake from sleep and remains experimental.
SATA2 still hasn't yet been fully saturated even by performant 3. The even the fastest current-gen 3.
