State of eGPU for Macs – Catalina 10.15 Update

eGPU Resources, External Graphics Card 159 Comments

Overview

Today Apple releases Catalina 10.15, two years after the launch of macOS High Sierra 10.13 that introduced eGPU functionality. While there were no major changes to external GPU support in macOS, we’ve seen notable refinements in day-to-day use. Better app-level optimization, improved internal display acceleration, and Boot Screen through eGPU are the highlights of Catalina 10.15 for external graphics card users.

As more users migrate to Thunderbolt 3 Macs, the cries for eGPU support on Thunderbolt 1 & 2 machines are fading away. Thanks to our community support developers, Goalque and Mac_Editor, older Thunderbolt Macs continue to enjoy external graphics in macOS Catalina. What we’ve heard loud and clear is the omission of Nvidia graphics card support. Nvidia and Apple are acting as if they went through a bitter divorce with no option for shared custody. Users are meant to side with the brand that’s most essential to their computing needs.

Native Support

If you have a Thunderbolt 3 Mac computer, you’re in luck because this is the platform on which Apple has been building eGPU support. All you need is a MacOS-certified AMD Radeon graphics card + Thunderbolt 3 enclosure pairing that fits your needs and budget. There are eGFXs that come ready-to-go with a graphics card such as the Sonnet Breakaway Puck 560/570, Gigabyte RX 580 Gaming Box, and Blackmagic eGPU/Pro. As of fall 2019, these are Thunderbolt 3 Macs that have native eGPU support in MacOS 10.15 Catalina.

The 2018 Mac mini received preferential treatment in Catalina 10.15. Apple made changes to its firmware to allow Boot Screen Support through the eGPU-connected monitor. This feature improves usability tremendously. As a headless Mac with iGPU only, the Mac mini is a prime candidate for an external GPU. The challenge for day-to-day use so far is the need to connect a monitor directly to the Mac mini (HDMI or USB-C/Thunderbolt 3) in order to use FileVault or Boot Screen to switch between macOS and Windows. It’s reasonable to expect eGPU Boot Screen Support as a standard feature on Thunderbolt 3 and newer headless Macs going forward.

A more future-proof route is to piece together an eGPU yourself. This process takes more effort but gives you flexibility and upgradability. This is beneficial for both enthusiasts and first-timers. Enthusiasts get to have nearly full control of the features they want out of an eGPU. If you try eGPU out and decide it’s not what you expect, the GPU can be repurposed and the enclosure sold.

There is some homework to do in order to understand eGFX technology and what features are available. eGPU.io enclosure reviews go into detail on power delivery to the host computer, available expansion I/O ports, Thunderbolt 3 controller arrangement, power supply capacity and more. The options listed in the table below are currently available and best-suited for Mac computers. The ranking is based on the number of user builds in the past six months.

All Thunderbolt 3 enclosures available on the market are macOS compatible. The bigger compatibility unknown rests on the graphics card. Apple only provides native eGPU support to select AMD GPUs shown below. They are currently the families of Radeon Polaris and Vega cards. Navi cards have yet to receive drivers in the initial release of Catalina 10.15 but we expect support for them soon. As a precaution, Vega 64 GPUs demand a lot of power. Therefore the eGPU enclosure should have at least a 650W power supply. Polaris GPUs such as the RX 580 are more efficient and can work with almost all eGPU enclosures.

Once you have the whole kit together, it’s plug-and-play with a Thunderbolt 3 Mac. Hot-plug and surprise removal of the external GPU has been working since 10.13.4. Catalina 10.15 also has much better support for multiple eGPUs. In High Sierra there appeared to be a limited number of eGPU the system could handle based on the host computer’s Thunderbolt 3 controllers. Mojave 10.14 raised this multiple eGPU support to four units. Catalina 10.15 has no set limit in my testing. The bad news is the system and applications can only use up to four eGPUs concurrently.

The most exciting feature is the ability to accelerate a Mac’s internal display with the eGPU. In previous macOS builds, the external GPU could only provide acceleration to OpenGL tasks rendered through an external monitor. There’s now a checkbox to set the eGPU as the preferred graphics card for all tasks regardless of whether an external monitor is attached. This mode forces eGPU loopback to the internal display of a MacBook Pro or iMac. With that said, not all applications are optimized for eGPU use. Adobe CC 2019 has support for external and multiple GPUs in some of its apps such as Lightroom and Photoshop. As more users adopt external graphics and as drivers mature, we hope third-party software support gets better.

Community Support

Similar to macOS Mojave 10.14, Apple does not extend eGPU support to users with Thunderbolt 1/2 Macs or Nvidia graphics cards in Catalina 10.15. Our community has been relentlessly providing unofficial eGPU support for these older Macs Apple deemed unworthy. The main developers are Goalque and Mac_Editor. Without their selfless contributions eGPU for Macs would not be as popular as it is today. There are currently two primary approaches to facilitate eGPU support on older Macs. One solution is to make a Thunderbolt 1/2 Mac behave like a Thunderbolt 3 Mac. The other solution is to make an eGPU behave like an internal PCIe graphics card. Keep in mind Mac computers with the Apple T2 chip have tighter security in place. In order to implement these solutions, Secure Boot must be off and external source booting must be enabled.

Purge-Wrangler by Mac_Editor is currently the easiest solution to enable eGPU access to your Thunderbolt 1 or 2 Macs. This workaround also incorporates patches that enable compatibility with older AMD and Nvidia graphics cards as well as TI82 Thunderbolt 3 enclosures. The prerequisites are for SIP to be disabled and patching made to system files. The table below lists the Thunderbolt version of Mac computers built from early 2011 to late 2015. You can either use a Thunderbolt 2 enclosure for external graphics or use a Thunderbolt 3 enclosure via a Thunderbolt 2 cable + Apple Thunderbolt 3/USB-C to Thunderbolt adapter.

EFI automate-eGPU solution by Goalque is a cleaner approach in that all patches happen on the fly during macOS booting process. The software can be installed on an external boot volume such as a USB thumb drive or a small FAT partition of your Mac’s internal hard drive. The former is strongly encouraged so that there’s no risk of corrupting your drive and losing data. Using an external drive for each boot is not convenient, but it’s well worth the effort if you’re not willing to disable SIP and modify system files for eGPU support.

A refinement in macOS Catalina is the addition of a GPU tab in Activity Monitor. Not only does it provide a close watch on whether the eGPU is being used, but it also shows other information on the external graphics card such as brand, model, enclosure, and connected Thunderbolt 3 port. While daisy-chaining of external GPU is not recommended due to limited bandwidth through Thunderbolt 3 interface, it works regardless. I have daisy-chained three levels with the Radeon VII being at the end of the chain. For OpenCL task, the performance loss was minimal.

Boot Camp Support

Many Mac users who are interested in eGPU want to use it for gaming in Windows. We were hoping eGPU improvement in Catalina 10.15 would also mean better support for Boot Camp mode. The reality is that Apple still considers eGPU use in Windows a non-priority. We had seen beta builds of macOS Catalina 10.15 directly affect the way eGPU worked in Boot Camp. Unfortunately there’s no one clear solution. It’s easier to set up an eGPU with Boot Camp in iGPU-only Mac computers; dGPU-equipped Macs such as the 15″ MacBook Pro pose a challenge. Our Boot Camp eGPU setup guide provides more technical information and the step-by-step process for Thunderbolt 3 Mac users.

While both AMD and Nvidia have made great strides in eGPU support for Windows, Apple does not adhere to the ways Windows computers interact with Thunderbolt 3 eGPUs. I’ve been testing the 2018 15″ MacBook Pro. The Mac firmware and Apple T2 chip are big hurdles to successfully set up an external GPU in Boot Camp. The only saving grace is that it has Large Memory allocation to help with error 12 when adding an Nvidia eGPU. As seen in the screen capture, adding an AMD eGPU in Boot Camp can wreak serious havoc to the system. Both the Radeon Pro 555X dGPU and RX 580 eGPU got yellow-banged with driver conflict and lack of resource issues.

There are advances and setbacks from Microsoft’s Windows 10 Fall Update. Version 1903 continues to improve upon Windows Hybrid Graphics (introduced in 1803) that allows the external GPU to work with a discrete GPU for internal display acceleration. This is beneficial for Mac computers because Apple firmware has a tendency to disable the Intel-integrated GPU in favor of the AMD Radeon discrete GPU. Without an active iGPU, AMD XConnect and Nvidia Optimus can’t leverage eGPU acceleration to the internal display. As seen in the Graphics Settings of Windows, you can set your preference for a given software or game to use the higher-performing external graphics card. Boot Camp eGPU users need to be careful of Security Updates which take place automatically. The recommended Windows 10 1903 is OS Build 18362.295. Once your Mac is running this version, make sure to disable Windows Update in Services.

Apple has made incremental changes to Mac firmwares in each macOS build. For example Mojave and Catalina improved the 2013 Mac Pro in that they allow more Thunderbolt devices to function in operating systems other than macOS. This is a nice ability for a Mac that received no love from Apple since inception. Although not officially announced or supported, trashcan Mac users have an upgrade path from the outdated FirePro dGPUs through external enclosures in both macOS and Windows.

Closing Thoughts

Catalina 10.15 has shown positive progress for eGPU Mac users. Hot-plug capability, internal display acceleration, and multiple eGPU support can truly transform a seemingly gutless Mac mini into a powerful workstation (an affordable one at that vs. the 2019 Mac Pro). Our community remains committed to providing eGPU support for older Thunderbolt Mac users. We’re also hopeful Apple will continue to improve Mac firmwares to make eGPU in Boot Camp a more straightforward process. The jury is still out on who’s the bitch in the failed relationship of Apple and Nvidia.

One more Thing

A better-implemented Sidecar in Catalina and future macOS versions can leverage eGPU to make a hybrid touchscreen Mac. Imagine a new iPad Pro lineup that has a matching footprint to the topcase of a new MacBook Pro lineup. You would then be able to place the iPad Pro on top of the keyboard and trackpad area to use it like a drawing pad (extended display mode). Sidecar can make use of an eGPU to accelerate this drawing pad. There should also be a Sidecar app on iPadOS. This would benefit headless Macs such as the Mac mini (primary display mode). In its current implementation Sidecar display cannot be the primary display. Once we’re able to use a Sidecared-iPad as the primary display, we have ourselves a wireless touchscreen Mac. For users who would not entertain a tablet as their computer replacement, Apple can make its iPads the essential complementary accessories to Macs.

I am using a Windows To Go (with BootCamp drivers) with Mantis Venus, will it continue to work as before? 

siyuanchu

@itsage
It works as before, but I am going to replace the 2060 with a Navi after 10.15.1 anyway. The 2060 caused me too much inconvenience on my Mantiz and macOS. I don’t want to deal with them anymore.

…and now we hope that they will introduce thr NAVI drivers in the next Beta versions!! Finger crossed!

Still white screen of death for me upon boot (Mini 2018 + RX570 w/ Zotac Mini). 🙁

JK Park

Same issue with my ampbox mini +msi rx580 v1 8G

It worked with no problem, but just as I upgrade to catalina,
It shows white screen after Apple logo.
Don’t know the reason but, Looks like it’s issue with zotac ampbox only. (Identical issue)

So I’m worrying whether Apple gonna fix this…
Not many users would use this egpu box…

But turning on and off the box doesn’t take that long..
So I would like to keep using catalina..

steve4332

@JK Park
“Luckily” several other eGPU models have this problem (there are reports with Razer Core X, Akitio Node, and Sonnet, all with RX570/580 cards). This might not be eGPU box related issue but a problem with the Polaris driver (as @itsage theoretized) and maybe a card firmware compatiblity issue which affects mostly RX570, 580 cards. AFAIK nobody has this issue with Vega cards. Let’s hope Apple fixes this soon.

any updates on this issue?

@Shad0wca7

Can you explain a little more about your fix? Im having apple logo (larger than normal) then “no signal” on the monitor

Shad0wca7

That’s exactly what I had – I just went into recovery mode, startup disk security and changed it back to full (had switched it off previously).

That seemed to sort it out when booting. However I’ve noticed now that more often then not when I go to “safely unplug the gpu” using the system tray icon the system will hang and reboot…

Ted Dawson

Ok thanks I’ll try that – are you on Catalina or Mojave? I heard this affects the RX400 and 500 series I was thinking of getting a Vega 56 if it would solve the issue

@itsage it may be the case that automate-eGPU EFI does not work on macOS Catalina. Hopefully should not be too much trouble to fix for @goalque (might be helpful to check updates to Clover), if he has time.

Mojave 10.14 raised this multiple eGPU support to four units. Catalina 10.15 has no set limit in my testing. The bad news is the system and applications can only use up to four eGPUs concurrently.

In Catalina, can all the GPUs support a display? Or can displays only work when connected to the working four eGPUs?
Can one app use 4 eGPUs, and another app use a different set of 4 eGPUs, so that more than 4 eGPUs are used?

Great news guys ! Apple just released first beta for 10.15.1 !
According to Apple’s release notes, ‌macOS Catalina‌ 10.15.1 introduces support for the AMD Navi RDNA eGPU architecture !!!

So now we have official support for the 5000 series ! Yay !!!

It should work fine. I have a 5,1 running Gigabyte RX 580 and upgrading from Mojave to Catalina went smoothly. Keep in mind the 2009 and 2010 Mac Pro do not have official support for Catalina. Therefore you need to do some prep work. The most important piece is Boot ROM version. The second essential piece is the macOS installer patcher from dosdude1.com.

Please forgive me, I don’t know much about this process. When you say that I need Boot ROM version, what does that mean exactly? Thank you!

Posted by: @steve4332

Before the screen turns white I see a few magenta lines appear on the top section of the screen for less than half a second (both HDMI and DP).

Thanks for the detailed response. This happens on my MBP for Vega as well, after which all is well.

Sadly all this sounds like a firmware issue. Apple really messed up the Catalina launch for 2018 mini. 

steve4332

@mac_editor
However: if I connect a second display to the iGPU HDMI port, the boot screen appears on the HDMI display (the firmware seems to prefer it to eGPU) and the eGPU display is sleeping during boot. In this case the login screen appears normally on the eGPU (since in the OS this is selected as primary display) and there is no white screen of death! This is not a very practical setup however (I don’t have a need for a secondary display permanently connected to iGPU).

steve4332

Posted by: @itsage @steve4332 That’s a good point. I believe both @joevt and I have a smaller monitor connects to the iGPU. In my setup, the Boot Selector remains visible through the eGPU-connected monitor. What if you connect both HDMI and DisplayPort to your monitor? HDMI from iGPU and DisplayPort from eGPU. In Windows we can easily set to show one monitor only, I’m not sure if there’s an easy way to choose only eGPU screen in macOS.   I tried this. Unfortunatelly there is no way to disable a secondary display in MacOS. You can set it to mirror,… Read more »

@steve4332

This would essentially indicate that the eGPU bootscreen support is still work-in-progress. Otherwise Apple would have updated their document regarding Mac mini eGPU support here: https://support.apple.com/en-us/HT208544

Notable though is that their recommendation for Mac mini only applies if FileVault is on, but white screen issue occurs even without FileVault. Hopefully we see a resolution by 10.15.3 at least. Typically around the .4 release Apple plans to bring some more significant under-the-hood changes (and sometimes these changes are split between the .4 and .5 releases).

Hey all! Just wanted to report that I’m on Mac Pro 5,1 (Late-2013 “trash can”) and my eGPU is not working with Catalina. It was working fine in High Sierra. Setup is Sapphire RX580 and Sonnet eGFX Breakaway Box. Hoping Apple will release an update to fix things up as my company just bought this a few months ago to breathe new life into my aging Mac as opposed to having to buy an entirely new system. 🙁

I’ve tried it about three times now. Have even tried a full uninstall and reinstall to no avail. Thought it might be related to others here saying that the RX570/580 is having issues with Catalina.

@cpokrywka

What version of Catalina are you running? Please also share build number.

cpokrywka

@mac_editor It wasn’t working for me with the initial 10.15 mass release build and still isn’t working with the latest supplemental update. Using purge-wrangler. Native graphics are Dual AMD FirePro D300 2GB. Have tried plugging the cable into all ports and nothing. Enclosure powers up when I turn on my Mac but nothing is displayed on my Cinema Display nor my external monitor just black screens.
 

mac_editor

@cpokrywka

The initial release of Catalina is definitely supported, so I’m not sure what’s going on with your particular setup. I cannot say about the supplemental update.

Edit: Supplemental update is also supported. Please share logs of script run (take screenshot at every question asked), share screenshots of System Report > Displays and PCI section with eGPU connected. I also assume that the card is appropriately powered (all power cables plugged) and assembled. 

Also add your config. to your signature.

The new firmware defo changed the way TB3 works in Bootcamp. My egpu works and is detected just fine using rEFInd (EFI Bootloader didn’t work) but I have to hot plug my Ultrafine pretty much. Its not consistent. One boot it will be ok, one it will be blank and I have to unplug and replug. Have had it go blank a couple of times during gaming too. I’m thinking it really is time changed display.

mac_editor

@itsage

Indeed. In one link it was mentioned that the Genius Bar diagnosed it as a hardware issue unrelated to the software update. As with your scenario, we guesstimated a lot of possibilities, so diagnosis in this situation is very difficult, compounding the problem. Of note is the fact that this bricking is occurring on older macs (pre-2015). After Yosemite, all odd-numbered releases have been problematic QA-wise IMO.

omardesu

Wow… this is just horrendous…  My 2016″ MBP was the first one that I updated, no issue there.  I think I updated my wife’s 2013 Macbook Air after that and that too didn’t have any issues.  My Mac mini is the only one that is still on Mojave, and I guess I’ll keep it that way…  I’ll double check the MBA again, but I do believe I did update.
Stay vigilant all.

PaulJ

Take it from someone with a 2018 MacMini who made the colossal mistake of “upgrading” to Catalina: DON’T DO IT! I would wait for at least two more versions of Catalina. I’ve had Macs since 1984, and never had these kinds of issues with a new OS.

Joe

I wouldn’t upgrade. It’s taking Nvidia a million years to even get to drivers to Mojave, if they ever. It’s going to be lightyears until they get around to Catalina. Apple just keeps dropping the ball…

Same here, exact same eGPU setup as yours, only with a 2018 MacMini. My eGPU runs all of the time regardless of whether the Mac sleeps. Do you think it would be better to turn off the eGPU manually at night, or just leave it running all of the time? Thanks.

Hi all,
My setup is 2018 Mac Mini (8th,6C,B) 64GB Ram + Radeon Pro WX7100 @ 32Gbps-TB3 (Sonnet eGFX Breakaway Box) + macOS 10.15.1
I also tried switching the eGPU between ports and have the same result. I can’t log in without disconnecting the eGPU and reconnect it.
I’ve contacted Apple support with no solution so far…
Only now I saw the info in the Sonnettech website that they don’t support Catalina with the Mac Mini 2018.

@Poison Monkey In a 2018 Mac mini?

My setup runs fine, both in passthrough mode (eGPU <> MacMini > Display) and direct mode (MacMini > eGPU > Display). Unigine Valley shows scores of 2500 and 3500, respectively. Yet, my Trainz game shows no difference between those two modes, presumably because in both cases Activity Monitor shows a maximum bandwidth of 5 Gb/s used 100%. 
Why only 5 Gb/s? The OP also shows this 5 Gb/s value.
I’ve tried different TB3 cables, but no difference…

I noticed iMovie doesn’t use my egpu at all. Really lame – spend all this money and it only works on certain apps 
.  Vega 56 works “ok” on Catalina. I think in Mojave the egpu did more in iMovie 

TheMadTurtle11

@hkoster1 I believe that’s a Navi card and my understanding is that the issue only presents itself with cards using the Polaris architecture.  Someone correct me if I’m wrong.

hkoster1

@TheMadTurtle11
Mmm… I still have a Vega 56 card lying around. Are you suggesting that I could get higher bus speeds with that older card? Wouldn’t be hard to test, so stay tuned.

hkoster1

Thanks @itsage , I’m just trying to find out why Unigine Valley improves score/fps when using the direct eGPU > Display connection, and my Trainz game does not. The game devs claim that the CPU > eGPU bus is already saturated when using the passthrough connection (eGPU <> Mac Mini > Display), but somehow that conclusion doesn’t feel right.
BTW, my Display is the LG 23.7-inch 4K UltraFine,  and in the direct connection I’ve used both the Moishi DP > USBC cable and the Huawei VR2 cable, both work well.

I am having screen freezes while using applications on the screen driven by my egpu. It happened while using Firefox and Substance Painter. Hot unplugging and replugging solves the issue for a while, till it happens again.

Interested in early feedback on functionality for those who upgraded to macos Catalina 10.15.2 official update ( https://support.apple.com/en-gb/HT210642 ) together with macbook pro and RX 5700

Don’t. 
Stay on 10.15.1 for now. A couple members have already posted about issues with 10.15.2.

@Loic Bonvarlet I would stay on 10.15.1 for now – I haven’t seen anybody else corroborate my issue yet, but after updating to 15.2, I can no longer boot with my eGPU attached. I have to boot with HDMI connected, then plug the eGPU in at the login screen. This also means that booting into Windows is no longer straightforward, as I can’t get a boot menu with the eGPU connected, either. It appears that I’ll have to shut down completely, unplug the eGPU, plug in HDMI, then turn the mini on and select my boot device, then connect the… Read more »

Thanks for all the comments. Seems like a new version will be needed to stabilize all this…

Hi

I just updated to macOS Catalina 10.15.2 official update.
Initially, the eGPU icon in the menubar disappeared.

But after uninstalling purge-wrangler and re-installing purge-wrangler,
everything was back to normal (same as 10.15.1)

Hope this helps everyone.

I’m having an issue with all my machines where the egpu is NOT rendering, the internal GPU is. This is on a MacMini, 13″ & 16″ MBP, all running catalina……Exporting h.264 files. It’s great having a checkbox/settings to use the eGpu to render inside FCPX but NOT if it’s literally a dumb checkbox!!
 
Anyone got any workarounds? This is so reminiscent of why I joined this site 2 years ago…..

I accidentally updated 10.15.2, haven’t encountered any problem so far.
ProRender still works with both dGPU and eGPU.
