I can only comment about Mojave.

Following a recent security update, providing my display is plugged into both my Mac mini and Razer Core X,  on boot-up everything is fine.

Can confirm a similar issue with Radeon RX 580 8 GB in Sonnet enclosure on the newest macOS Catalina 10.15.6 Beta (19G60d).

The filesystem is encrypted, so I can see the first prompt to enter my password and later it stuck on the boot picture.

Inspecting system logs didn't add much insight into what is the problem.

Heres the email I got from them

Hello Ted,

When you upgraded to Catalina, your Mac mini got a firmware update that cannot be reversed. You can wait for the Catalina 10.15.1 release that hopefully should fix the issue. If you need a GPU now, the Vega 56 worked in our tests.

Regards,

It's a year later, and I'm running version 10.15.7. But I'm having a similar problem: Mac mini 2018, Razer Core X Aluminum External GPU Enclosure, and XFX RX 5700 Xt Thicc III Ultra 8GB graphics card. With the monitor plugged into the graphics card, and the graphics card plugged into the Mac mini, sometimes it boots, and sometimes it doesn't. It's frustrating in the extreme to have just spent this much money only to have the whole thing be so unreliable.

I have two eGPUs:

- Mac mini running Big Sur now + Razer Core X Chroma + Vega 64 (no FileVault)

- MacBook Pro 2018 + Mantiz Venus + RX580 (and FileVault)

I was never able, in a reliable way, to boot with the eGPU attached, whatever the OS version I used them with.

 

I will most probably submit a new feedback to Apple about this.

Mac mini 2018 - 3,2 GHz Intel Core i7 - 32 GB RAM running 10.15.3 (19D76) - Mantiz Venus eGPU with AMD Radeon RX Vega 64 8Gb, Dell U2718Q (4K) connected to the eGPU via DP.

@psm, try this work around: leave the eGpu connected to the monitor and the Macmini to the eGpu (as you would for optimal performance) but at startup start with the Macmini and wait for 5 seconds before switching on the eGpu.

Hope this helps!
