Hi there...I have a dual eGPU set up with my Mac Mini 2018 6 core i7 with 32gb of Ram. I have dual Radeon 8gb 470s in a Sonnet 350 and a first gen Razer Core, which I used Purge Wrangler to enable Ti82 support. They are on separate thunderbolt buses as I read this helps bandwidth. 

I also have a Blackmagic Intensity 4k editing playback pci card housed in an external Sonnet thunderbolt 3 expansion chassis.

I have been running this set up throughout all the beta testing of Catalina up to and including the GM/public release and the only time I had problems with was beta 8 recognising the Razer Core. I downgraded then upgraded again when beta 9 was released...with no hitches.

The only slight issue I have is with having to re-plug in the Core after my machine has booted up. This enables my Mac to recognise it. There’s no white screen of death for me and the Sonnet based 470 is recognised at boot with no issues.

Software is hit and miss as far as performance.

After Effects is woeful...Photoshop and Illustrator aren’t too bad, as are Apple’s Final Cut Pro and Motion. I switched to Resolve from FCPX a while ago due to it’s feature set and can playback a few streams of 4K no problem. I know these are subjective opinion and I will run some benchmarks and publish them here when I have some spare time...but it’s quite a fast wee system and I don’t know about other creatives but I have always pushed my Macs to the limit as creativity demands it...so its never as fast and can do as much as we want lol.

I’m an illustrator/designer/filmmaker based in Scotland by the way...😁🏴󠁧󠁢󠁳󠁣󠁴󠁿.

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.

Yeah, it didn't. 🙁 This issue is probably somewhere at the bottom of the priority list or maybe it's not on the list at all. Affecting only some Mac Mini 2018 configs with some RX560/570/580 cards. I am afraid there are about 15-20 or so people complaining about this among millions of users...

you‘re right. 🙁 maybe this will Never ne fixed. Are RX590 Cards Not affected? Then maybe it would be the cheapest solution to switch to one of these..

I donno. Do anybody have an RX590? 🙂 Unfortunatelly I can only upgrade to an other ITX card (the Zotac Mini Box is limited in size). I am thinking about getting an RX 5500 which seems to be ITX by default. Not a very powerful card though. Of course it must be released first and I'll have to wait for OSX support.

Has anyone tried a Mac Pro 5,1 with the Sapphire 580? It looks like most issues being reported are with Mac Mini but I wanted to see if anyone has had experience with Mac Pro before I try to upgrade.

@steve4332 @fringedivision @shad0wca7 @themadturtle11 I read a recent post from @joevt experiencing the same white screen issue with his 2018 Mac mini + RX 580 eGPU. He provided the connection details which may be helpful to those of us in the same boat. TB3 Port #3 causes this issue for him but Port #2 does not. These two ports belong to different TB3 Controllers. I also found last night my 2018 Mac mini can only provide Boot Selector screen through the eGPU-connected monitor when the connection is through TB3 Controller #1 [TB3 Port #3 & 4]. If I connect the eGPU through TB3 Controller #0 [TB3 Port #1 & 2], it's a black screen when I hold OPTION at boot. Test these different connection arrangements and see if we can find a workaround until Apple fixes Polaris drivers.

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.
