Everyone is over the moon with the announcement yesterday at WWDC. Apple finally gave its blessings. Official macOS eGPU support is here. The general public won’t have access to this new feature until next spring. But if you’re the type who lives on the edge, here’s how you can get in on the action.
1. Be an Apple developer and buy its Metal 2 external GPU Development Kit ($599Â in the US).
2. Be an eGPU enthusiast and buy the components we have sourced together in this guide.
Overall pricing for either option isn’t much different. You’ll end up $600 poorer and spend many hours toying with this thing like it was your first computer.
The major change this eGPU support announcement from Apple is that software side of things in macOS is now no longer a hack of system files. The eGPU community has been enjoying external graphics cards for years thanks to the selfless work from Nando, Goalque, and Rastafabi. Dare I say what our eGPU community accomplished through countless eGPU implementations on macOS has prompted Apple to finally take action. It comes in the form of macOS 10.13 High Sierra.
Hardware wise, Apple didn’t do much for its Metal 2 external GPU Development Kit. It simply outsourced the Thunderbolt 3 enclosure to Sonnet, then paired that with an AMD Radeon RX 580 graphics card. The addition of a Belkin USB-C to standard USB hub is to allow Thunderbolt 3 Macs to use HTC Vive.
What do we know about these hardware choice? Fortunately, we tested and reviewed this exact eGPU pairing not too long ago. We concluded the Sonnet Breakaway Box 350 is a great enclosure for professionals. It runs cool and quiet. Pricing at under $300 is a reasonable value.
The other crucial component is AMD Radeon RX 580 graphics card. It has a $229 MSRP however due to high demand for their use in crypto currrency mining there’s currently a shortage of these Polaris 10 GPUs. What is available sells for well above MSRP.
Some of you may like other enclosures better. The good news is, as long as the eGPU box has TI83 USB-C controller, it will work with native external GPU support in macOS 10.13 High Sierra. For example, an additional US$30 for the Sonnet Breakaway 550 over the 350 model will see charging capacity boosted from 15W to 87W. That is enough to power even a 15″ Macbook Pro via a single attached Thunderbolt 3 cable and so is money well spent. Do you require additional ports on your enclosure so it is an all-in-one docking solution? Consider the Mantiz Venus from the Buyer’s Guide.
Besides the Radeon RX 580 GPU, there are a handful of other AMD graphics cards which share the same PCI ID. We prepared this table to show you the alternative components you can use to build your own Metal 2 external GPU Development Kit.

While Apple only mentioned Thunderbolt 3 Macs being supported in its release note, we have found the majority of Macs with Thunderbolt ports to be eGPU compatible. Take a look at our eGPU implementation list for successful Mac setup to get an idea whether your Mac would work. For quick reference, the table below details all Mac computers with Thunderbolt connectivity. Mac models with an asterisk (*) denote they have discrete graphics as a standard feature. If all goes well, you’ll see macOS detection of External Graphics as soon as you plug the enclosure into your Mac. Simply log out then back in to begin using the eGPU.

This was my attempt to connect all three TI83 enclosures I have to a late-2016 15″ MacBook Pro. macOS High Sierra detected all three without issues. The limitation I found is due to the MacBook Pro having only two Thunderbolt buses, the system may only use upto two eGPUs at once. Seeing the huge OpenCL performance boost, there’s little to no reason to complain about this limit. 😀Â

Great news, I believe we shall wait for VEGA Cards to have the best of both worlds (macOS & Windows) despite which one of the above listed four enclosures.
What do you think @itsage?
The smart thing to do is to wait. The fun thing to do is to not wait. 😀
“599 USD or in local currency”
In Switzerland it costs 900 USD (869 CHF)
That’s very expensive then. There seems to be a price hike for EU & UK on Apple products.
Yes… 889€ in France
My Node setup in France :
349€ For the node
35€ tb3tb2
49€ Tb2–tb2
Plus the card … mine a used one at 350€ on price minister 😉
Similar prices in New Zealand: NZ$1349 ~ US$970
Seems like the dev kit is a good deal if you’re in the states but cheaper to piece it together yourself otherwise.
Thank you for sharing the pricing in New Zealand. This is exactly why we prepared this guide for those who need alternatives.
I already had an Akitio Node to use with my 13″ MBP, but it had a GTX 1050 Ti that worked well. The promise of a fully-supported configuration was just too tempting, though. I spent (ugh) $369 on NCIX yesterday to get the only model they had in stock. Cheaper than the $500-700 third-party sellers are asking on Amazon and Newegg, though. Hopefully it’ll be here early next week.
You mean $369 for an RX 580? It’s bad timing due to high demand from mining community.
Not sure if I read it right.
I have a Macbook Pro 15″ Retina (Late 2013) (GT750M). Unfortunately the laptop has a thunderbolt 2 port and no thunderbolt 3.
Although, I clicked on the eGPU Implementation List, and saw that my Macbook is on there.
Could I connect a eGPU (by using e.g. a Sonnet) via Thunderbolt 2? Or can I expect the results to be worse.
The performance of Thunderbolt 2 is lower than Thunderbolt 3 but your 2013 15″ MBP should be able to use an eGPU. If you’re getting a Thunderbolt 3 enclosure such as the Sonnet Breakaway Box, you’ll need the Apple Thunderbolt 3 (USB-C) to Thunderbolt adapter.
So would I notice this difference in performance between TB3 and 2? Would you say that you can’t get everything out of it with TB2?
I am looking forward to this for years. Especially native support by Apple. I just want some proper GPU power 😉
@itsage: Hello Sir. At this moment macOS 10.13 beta, internal display doesn’t working with eGPU. From your experience, do you think they will implement this feature in future updates?
Definitely. There’s a workaround to trick the eGPU into accelerating the internal display of a Mac laptop. However, it reduces performance significantly and is not worth it. Apple now has a team of engineers working on external graphics support for macOS (and AMD engineers as well). eGPU for Mac will be a much better experience next spring.
Sorry for my ignorance, but does this mean the official Apple eGPU’s will only come next Spring?
Yes. Next spring is when eGPU feature becomes widely available for Mac. Right now it’s in beta for developers only.
What gbps do I need for 60hz 1080p
I wounder if that apple GPU kit will work in Windows 10 since i have Windows 10 installed under bootcamp.
