So, if I'm buying a GPU for my 2018 MacMini Core i7 - do I save money while waiting and spend around $180 for an  RX 580, or should I get the RX 5700 XT and wait for the drivers to normalize?  Or is it so bad that I'd see better perf with the RX 580?  I'm not going to be gaming, or boot camping.  I'm going to be using it for compute in things like Final Cut, etc.

It’s a known issue with Navi on TB1/2: https://github.com/mayankk2308/purge-wrangler/issues/44

Just set up using the script without plugging the eGPU in. This is also mentioned in the Beginner’s Guide footnotes. 

Huh, I must have missed that in the guide. Thanks though, as this was helpful and did solve the problem.

Nice! It seems to be an odd issue and does not occur with any other AMD cards. I could change the script to force users to eject eGPU (so workflow would be plug in -> detect -> eject -> patch) but that felt unwieldy so haven't incorporated it (might do in case more people miss the guide).

I am not sure simply ejecting would be enough. My scenario went like this,

1. Boot machine 10.15.1

2. Install 10.15.2 upgrade

3. Installer reboots machine

4. Kernel panic on boot - reboots endlessly

If you eject in a "2.5" step, it would still be physically attached when the machine reboots and is likely to be detected. I had to physically unplug it to get the machine to boot again.

What worked for me:

1. Unplug egpu

2. Boot 10.15.1

3. Install 10.15.2 upgrade

4. Installer reboots machine

5. Run pure-wrangler.sh and install w/o detection, amd, no legacy, no ti

6. Plugin eGPU

7. Profit

By eject, I meant physically ejecting. If the issue occurs in macOS without script running - like just plugging it into a TB2 Mac and crash - then nothing can be done (besides not connecting it). I was under the impression the issue occurs when the script rebuilds kernel cache and Navi GPU is plugged in. Fortunately, this is not a huge roadblock and setting it up without the eGPU plugged in is still (hopefully) not complex for newbies.

Just wanted to add a data point to the thread. I ran geekbench 4 & 5 with RX 5700 XT in Core X Chroma enclosure with Windows 10 & MacOS Catalina. Apple's got some work to do bringing performance to MacOS for this GPU 🙁

You can see results here:

Geekbench 4

  1. Windows 10: Score 196851
  2. MacOS: Score 115762

Geekbench 5

  1. Windows 10: Score 71796
  2. MacOS: Score 34650

GB is erratic and unreliable re: Mac OS. 

Don’t bother with GB.

Use Basemark for Mac OS Metal API.
