Hi all, I've read alot of info here, but still haven't been able to figure out my specific problem. Any help would be appreciated.

My setup: 2019 MBP. Mac OS Catalina 10.15.1. Windows 10 bootcamp. internal gpu: Radeon Pro 560X

Tried a PowerColor red dragon radeon 5700 XT on a Razer Core X.

When I plug in the egpu, the Mac OS goes into an endless reboot loop. When logging in, the load bar gets about 2/3 of the way there then crashes.  (I read someone else here had exactly the same problem with this particular card.)

On windows 10 bootcamp, it doesn't crash but also doesn't recognize the card. Under device manager, it shows a video card, but just says "error."

I returned the red dragon thinking maybe this wasn't the best choice. Thinking about trying a different card. Maybe a Vega 56?

Any guidance you guys could provide would be much appreciated!

Likely faulty GPU (have same exact model 5700 XT). RMA fixed the problem. Seems like this model might be prone to failures given including your case I’m now aware of 3 on this forum itself. Your username is on-point regarding the issue Smile

Ha! Thanks a lot!

Do you think trying a Vega 56 on this setup would work better? Or should I buy a different model RX 5700 XT? (Was thinking maybe MSI...)

I believe you should be fine either way. Vega has more mature drivers of course.

Sounds good. I'll try a new card and report back.

Update: It was definitely a faulty card. Bought an XFX Raw 5700 XT  -- yes an inferior card, but hey it was cheaper -- and it was plug n play on Mac OS Catalina. On Windows 10 bootcamp had to downgrade to an earlier build to get rid of error 12. After that worked fine.

Now I just have to figure out why I'm only averaging 30 fps on red dead redemption 2 ultra settings. This card should easily get me 60 + fps.
