@berkan, did you get your setup working?

I have a similar configuration but with an RX 580

2020 13" Macbook Pro Coffee Lake

16GB

512GB SSD

 

Razer Core X Chroma - works great in MacOS Catalina

Windows Troubleshooting steps so far:

  • Latest Fast Ring Insider's edition
    • hot-plugging the eGPU results in Error 12
    • power cycle with eGPU plugged in results in either reboot at the Windows logo or stuck at Windows Logo indefinetly
  • Downgrade to 1903 following instructions
    • hot-plugging the eGPU results in green screen of death
    • power cycle -same as Fast Ring

It seems like there are not many people running this MacOS setup with an eGPU.  I am open to any suggestions.

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@joevt, My 2019 13-in MacBook Pro has model name MacBookPro15,2. It's a work laptop and hooked up through an RX 580 eGPU that powers 3x FHD monitors. I will bring a TB3 to 2x DP adapter to test your suggestion. I looked in SwitchResX but couldn't locate the "Activate Immediately" button. Can you provide some screenshots?

@itsage, It's in the Custom Resolutions tab. You create a custom timing. It says "modified" at the bottom, which means you can press Command-S to save changes. Then the Activate immediately button appears (bottom right corner).

 Here's some screen shots:

I have the same issue. But weirdly enough I updated macOS to Cataline 10.15.5, then reinstalled a clean build of windows 10 2004 19041.264. The rest was plug and play... just after installing the Bootcamp drivers, plugged it in, BAM!

@itsage, After talking to apple support and getting my performance logs today they came back with their verdict. 

Apparently there is a firmware bug affecting the t2 chip introduced with the 10.15.6 update which is the reason for my 2020 mbp i7 underperformance. Supposedly will be fixed in the next update. 

Maybe is fixed in Big Sur beta. Are you testing Big Sur on a partition or a VM? 

 

Best

@tsakal, Big Sur Beta is still a mess in my observation. I have it running on 3 Macs. The only non-T2 Security Mac, 2013 Mac Pro has been the most predictable. 2018 Mac mini and 2019 13-in MacBook Pro have been confusing during the upgrade procedure. My Mac mini has gone through Beta 3 installation half a dozen times but it never actually did the upgrade.

@itsage, Thank you I have been talking to @andygev35 and he is on the same boat. 

As I mentioned apple admitted to me that since their latest update to 10.15.6 they have issues with the t2 chip. 

@itsage, @andygev35

The problem is that even I try to go back to 10.15.4 the firmware will not change. Correct?

Hi All

New member here - I have 2020 13” MBP 10th Gen with eGPU / enclosure as shown - I am getting error 12 in Windows boot camp - Windows version is totally up to date and patched (I know that’s probably my first mistake!)

eGPU works perfectly in MacOS but I am failing miserably to get it running in Windows 10 boot camp - has anyone actually managed to get this running successfully on up to date Windows 10 please? - I am loathe the revert to an older build for security reasons...

Any constructive advice / how-to’s would be most gratefully received!!

Cheers

I hate the T2 chip. The startup process is horrible on my Mac mini 2018 - inconsistent - sometimes a double chime when switching between Big Sur and Catalina, sometimes it hangs (no keyboard caps lock function) and I have to power it down and try again. Sometimes it boots quickly, sometimes not. Sometimes the Apple appears immediately, sometimes not. I couldn't get into the Startup Security Utility on Big Sur (and Catalina) for awhile (it wouldn't accept my admin password even though Recovery did), so I reinstalled Big Sur.

I have Big Sur working on Thunderbolt NVMe (previously was running from USB NVMe). I installed to a new partition (either HFS or APFS - it will convert HFS to APFS). Then I use Migration Assistant to copy apps/settings/docs from Catalina or other Big Sur install.

I can usually boot with eGPU connected (no boot screen on 5K display either with AMD or Intel graphics - but 4K display works).

You can't get old firmware to install by going back to an old OS (unless there's a force option?).

@joevt, Same experience with my 2018 Mac mini. It's guess work every time the system boots up. Except for a brief period of time (10.15 beta) when there's reliable boot screen support through the eGPU, I could never tell what's the computer is doing following a restart/cold boot. Made even worse when the boot chime was removed. I wonder if this is why they brought it back.
