[Solved] macOS Catalina - should eGPU Bootcampers update?

I've got another report encountering the same issue as a few of the users above.

MacBook Pro 15in (2019)

RTX 2060

Razer Core X

If the eGPU is plugged in at boot, the option-key boot menu will not show up and I'm stuck at the Apple logo. If I leave the eGPU unplugged at boot and reach the boot menu, plugging in the eGPU will immediately freeze the boot menu, and the boot partition cannot actually be selected. 

If I have the eGPU attached at boot and the Bootcamp partition blessed to bypass the boot menu (via Startup Disk in macOS), I get stuck at a white spinning circle against a black screen that I haven't seen before, and I suspect is new in Catalina. 

If I have the eGPU attached at boot but blessed to boot into macOS, it boots successfully (but since I have an RTX GPU it doesn't do anything).

I can also confirm that hot plugging the eGPU once Windows is booted does still work, but make sure to watch out for the code 12 hot plug error everyone's running into currently ( https://egpu.io/forums/pc-setup/egpu-fail-after-update-to-windows-19-03/

I reset the PRAM and SMC which didn't improve anything. Having to hot plug is a little annoying (especially with the code 12 error on the latest Windows 1903 builds), but it at least works for now. Hopefully a future Catalina update fixes the eGPU at boot when getting into the option-key boot menu and also Bootcamp.

I have noticed and seen reports of RTX series graphics cards having firmware compatibility with Macs. There's something very different in the RTX cards firmware because they can provide boot screen for the Mac Pro tower. It's likely Mac firmware installed during Catalina system update is now clashing with RTX firmware at preboot. One workaround is to wait until Windows fully boots then hot-plug the RTX eGPU. 2018 and 2019 Macs should be able to use Nvidia eGPU through hot-plug in Boot Camp.

Seems to me the RTX firmware feature was an F-U from Nvidia to Apple - to make a superior graphics card that has a boot screen for old Macs so Mac Pro owners would complain more to Apple about missing Nvidia drivers. Now Apple responds with an F-U to Nvidia with Catalina. I might be confusing malice with something else though - maybe Apple didn't do it on purpose...

thanks for your help - I can confirm that by hot-plugging during the Windows logo I'm back up and running RTX 2080 super bootcamp on MacBook Pro 15 inch 2018.

@joevt There's definitely a pissing contest going on. It's a mix of bad blood from past dealings and stubbornness on both sides. I recall Nvidia was making a powerplay in 2013 by announcing it would offer Kepler and future GPU IP to 3rd parties. They approached Apple and other hardware makers but everyone told them No because their licensing costs and terms were out of line. Nvidia proceeded to sue Samsung and Qualcomm but avoided Apple for good reasons. Apple started their in-house GPU development. They have been going vertical aggressively in the past five years.

Meanwhile AMD was going through a leadership transition and ended up benefiting from Apple's beef with Nvidia. They needed business now and couldn't care less if Apple ditches them once the in-house GPUs are ready. AMD focused on their own strengths and that strategy has paid off handsomely in the past couple of years. As long as AMD remains a committed supplier with cost efficient dGPUs, Apple will take their time switching to in-house components. Microsoft refuses to join Thunderbolt pack is drama for another day. LoL

brilliant summary, well done

 

I am sticking with AMD until such a time as it becomes more convenient to switch. Moreover, while I am play testing the 5700 xt for fun the vii is perfect as it has the power to game and the flexibility to just be left plugged in to run my mac.

As the Catalina upgrade has not been great (reading both on reddit and here), I will remain at Mojave... it's perfect and the hot switch ability is not critical to me...

Can you see the boot screen without direct connect from mac mini to monitor?

even i upgraded to catalina, i still have to connect the mac mini to the monitor with a hdmi cable for the boot selection screen

Agree.  My Akitio eGPU boots up fine into Windows 10 plugged in, if I remove RTX 2080 card.  Clearly it is related to RTX card's firmware's interaction during pre-boot.

Yeah. My GTX 1080 on the other hand now has boot screens and even gets to the point of displaying the macOS desktop for only a second when booting Catalina.

Goes to show that Apple could have made this work long ago had they actually wanted to.

Macbook pro 2018 i9 + RTX 2080ti + Razer Core X

I just update to Catalina. Now on Bootcamp I can't plug the eGPU before anymore. I have to wait for windows to load to hot plug it. Also, if I use the eGPU connected to the left side, and a Thunderbolt 3 dock on the right side. When I connect the dock after the eGPU, it immediately restarts 🙁 I was just able to use both by plugging in first the dock, then hotpluging the eGPU. If you don't need Catalina, I wouldn't upgrade.
