Though most of what Apple makes doesn’t allow for internal upgrades, the pre-2013 Mac Pro has room for an upgraded graphics card, and you can add an external GPU enclosure – like the – to the newest MacBook Pros by using the Thunderbolt 3 port. And then, of course, are those who have built a, unencumbered by Apple’s silly limitations.

Your Thunderbolt 3-equipped Mac running macOS High Sierra 10.13.4 or later can access additional graphics performance by connecting to an external graphics processor (also known as an eGPU). An eGPU can give your Mac additional graphics performance for professional apps, 3D gaming, VR content creation, and more.
With support for Pascal-series cards, Mac users now have access to the most powerful graphics cards currently available (by a huge margin). Not just a boon for gamers (macOS is hardly the most gaming-friendly OS, after all), it’s a welcome upgrade for anyone who works with complex 3D graphics, as well as high-end video production, where GPU acceleration leads to faster renders and smoother previews. The timing is likely no coincidence. Apple just (before next year), which includes updated AMD graphics.
Meanwhile, Microsoft just announced the specs for its upcoming. That uses AMD graphics, so maybe Nvidia is trying to stick it to Microsoft a little as well. Of course, the fact that it took so long to get Pascal to work on the Mac in the first place is worth acknowledging – if you want support for the latest and greatest graphics, macOS probably isn’t for you.

If you own the 1,1 or 2,1 Mac Pro your options are limited to a few GPUs: • Nvidia GT 120 • Nvidia 8800 GT • AMD Radeon 7950, 7970 or R9 280X if you have installed OS X Mavericks or newer via hack methods. We do not provide these methods, but information about them is readily available online. If you own the 3,1, 4,1, or 5,1 Mac Pro you can utilize any of GPUs we sell except for the GT 120 and 8800 GT mentioned above. Please be aware that while the 3,1 Mac Pro has the same GPU compatibility as the 4,1 or 5,1 that the older hardware of the 3,1 will result in some comparative bottlenecking.
