Don’t. 

Stay on 10.15.1 for now. A couple members have already posted about issues with 10.15.2.

I would stay on 10.15.1 for now - I haven't seen anybody else corroborate my issue yet, but after updating to 15.2, I can no longer boot with my eGPU attached. I have to boot with HDMI connected, then plug the eGPU in at the login screen. This also means that booting into Windows is no longer straightforward, as I can't get a boot menu with the eGPU connected, either. It appears that I'll have to shut down completely, unplug the eGPU, plug in HDMI, then turn the mini on and select my boot device, then connect the eGPU.

Interesting, I’ve upgraded to 15.2 too. Power on with egpu plug in, Bootcamp(295) works fine as usual, but MacOS occasionally will stuck on login screen need power off and restart, say 20% opp. 

hot plug then both OS working well.

Thanks for all the comments. Seems like a new version will be needed to stabilize all this...

I had this after the 10.15.2 update too. macOS got stuck during booting when the MacBook Pro is connected to the eGPU. Have to disconnect everything, boot up, reconnect eGPU.

Hi

I just updated to macOS Catalina 10.15.2 official update.
Initially, the eGPU icon in the menubar disappeared.

But after uninstalling purge-wrangler and re-installing purge-wrangler,
everything was back to normal (same as 10.15.1)

Hope this helps everyone.

I'm having an issue with all my machines where the egpu is NOT rendering, the internal GPU is. This is on a MacMini, 13" & 16" MBP, all running catalina......Exporting h.264 files. It's great having a checkbox/settings to use the eGpu to render inside FCPX but NOT if it's literally a dumb checkbox!!

 

Anyone got any workarounds? This is so reminiscent of why I joined this site 2 years ago.....

h.264 is handled by the encoder on the Intel chip because it more energy efficient and in some cases faster than the encoder on the graphics card. This also happens on Windows depending on the codec you are exporting too and which apps you are using.

It used to be handled by the egpu. Nothing is handled on rendering on the eGpu now. On the 16" the AMD handles rendering, on the macMini, it's the woeful internal graphics (was great before). I'm surprised there's nothing on here?? There's a thread on the apple site.... https://discussions.apple.com/thread/250714680?answerId=251776941022

I accidentally updated 10.15.2, haven't encountered any problem so far.

ProRender still works with both dGPU and eGPU.

Catalina eGPU is a complete trainwreck for me (Mini 2018 + RX 570). I can still not boot with eGPU attached. And now (after updating to 10.15.2) the TV app stopped working - trailers work fine but protected materials stop playing after about a second.

The TV problem is a log in bug. Deactivate, log out, then log in and activate again. It should work now.

eGPU boot bug is reported by many.

Common problem, usi Mac mini HDMI for boot, then plug eGPU

No deauthorizations, authorizations, logging in and out solves the problem for me. The TV app works with iGPU but fails to work with eGPU. This might be a content protection related issue that affects eGPUs.

Catalina eGPU support is simply substandard and things got even worse since the initial release. Apple seems to have serious difficulties solving its problems. 🙁

I’m on a MacBook Pro 2017 nTB model, with an Akitio Node enclosure and a Sapphire Nitro+ RX 580. Initially worked fine on macOS 10.15.2 for an hour or so, with the eGPU connected to my display through DP. Unfortunately after that it started crashing my games and is now causing full on kernel panics anytime I plug the eGPU in to the MacBook Pro. Have reset everything as well as reinstalled macOS but nothing seems to work so far.

Did you try removing and reinstalling the card and the 8-pin power connectors to the card?

I have, multiple times (I’m David). The RX 580 has a 6+8 pin, and I’m using 2*2+6 connector, so a two-pin is left sitting without anything in it. Is that okay?

Yes, but it sounds like a defective card, or enclosure, unfortunately. 🙄

Definitely sucks! I’ve now bought an RX590 to replace it and it works beautifully so far (fingers crossed it doesn’t crash). Only problem is that the RX590 only shows up on the external display and not on my Mac when I don’t have the external display connected

With the eGPU not working due to the card, do you think I should sell it as faulty or used to PC buyers? I don’t know if they probably have a way to fix whatever was causing the issue through BIOS or stuff like that.

Oh, but it can! Sometimes...😂

"You can configure applications to use an eGPU with one of the following methods:

Use the Prefer External GPU option

Starting with macOS Mojave 10.14, you can turn on Prefer External GPU in a specific app's Get Info panel in the Finder. This option lets the eGPU accelerate apps on any display connected to the Mac—including displays built in to iMac, iMac ProMacBook Air, and MacBook Pro:

  1. Quit the app if it's open.
  2. Select the app in the Finder. Most apps are in your Applications folder. If you open the app from an alias or launcher, Control-click the app's icon and choose Show Original from the pop-up menu. Then select the original app.
  3. Press Command-I to show the app's info window.
  4. Select the checkbox next to Prefer External GPU.
  5. Open the app to use it with the eGPU.

You won't see this option if an eGPU isn't connected, if your Mac isn't running macOS Mojave, or if the app self-manages its GPU selection. Some apps directly choose which graphics processors are used and will ignore the Prefer External GPU checkbox."

Perfect! I think this was what’s happening, even when I had checked this box Subnautica was ignoring the eGPU. I have Rise of the Tomb Raider downloading and have never played any of the games, so excited to see this will be optimized with the eGPU!

You mentioned: "Better app-level optimization, improved internal display acceleration, and Boot Screen through eGPU are the highlights of Catalina 10.15 for external graphics card users."

Are there any benchmarks for such facts?

Everyone with this issue should contact Apple, use feedback page or beta report. I have many fiends with this problem on Mac mini 2018, it is a nightmare

Am I understanding this: The problem is with the RX 500 cards, but not the Vega cards.  What about the RDNA cards?

I have a Vega 56, and ever since 10.15.2, I've had to leave my Mac mini connected via HDMI to my display (along with my eGPU connected via DP), or it won't finish booting - just hangs at a black screen. Also, the boot selection screen that appears when you hold Option on boot only shows via the mini's HDMI port, not via the eGPU. This was not the case with 10.15.1, where everything displayed fine via the eGPU and no connection to the mini's HDMI port was necessary.

That sucks because my mini showed up with 10.15.2.  I guess I'll stay on internal HDMI.  (I wasn't going to use DP anyway.)  I mostly wanted the compute power.

Has anyone tried 15.3? Im scared to update. I'm at 15.1 and im limping along. Im afraid it could get worse. I can boot but with purple lines and huge apple logo. imovie wont use EGPU and apps seem to sort of use EGPU but not as much optimization as I had in Mojave

I've read recently that we're supposed to do updates with the eGPU disconnected, which I didn't know. 10.15.2 was definitely a step back from 10.15.1, and 10.15.3 didn't seem to fix anything, but I didn't disconnect the eGPU during any updates, so who knows? Unless the updates are known to fix other issues you're having, I'd probably hold off.

ya im hesitant... the last updates I did with the eGPU connected and it crashed my system, I had no video out even with built in HDMI. 

I back u to a slow rotary HD so it took a day to restore my system. I can't risk it until I see some more evidence that it is stable.

@ted_dawson For a headless Mac, it’s best to disconnect the eGPU during system update. My 2013 Mac Pro firmware was corrupted during 10.15 beta. It was not a fun experience [link].

Damm, I didn't know that i always have updated my mac mini 2018 with the eGPU connected, won't do that anymore, maybe that is the reason i'm not able to select boot partitions with the eGPU connected and filevault disabled.
