Can't disconnect EGPU in osx, system shutdown instead

Hi all,

I'm experiencing some weird behavior on my setup recently. I have a 2018 macmini (i7, 16 GB Ram, Sonnet Breakaway puck RX570 EGPU) running mac osx mojave that I recently updated to version 10.14.6 (18G4032).

The problem is when I click the icon of the EGPU in the menu bar and select disconnect it, my 2 monitors connected turn black and my macmini shutdown. 

I was wondering, is this normal behavior with the release of this new mojave version? Has anyone experienced the same thing?

 

Thanks in advance for the help.

I have the same issue on my 2015 MBP with a Sonnet 550 Breakaway Box and a Radeon RX 580... I've just been hard pulling the thunderbolt from the laptop... Seems to be ok, reconnects fine every time... Would love to figure out how to disconnect it properly tho. 

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

I've updated with the latest security update for mojave and still ,unfortunately, the problem seems to persist.

Here is the bug report  I get when the computer automaticaly reboot (hope this help). It's in the attach file because it was too long to post here.

Ok I've reached out to apple support and they were unable to solve the issue. As they suggested to me, I try in safe mode, resetting SMC, trying a different thunderbolt 3 cable, none of these option worked. The only thing left is to sent the unit at an apple store for diagnostic but this will take a while. No one have an idea for what's there left to try? I'm out of idea myself!

@simon_jl, upgrade to Catalina and see if it helps. Are all monitors connected to eGPU? Maybe try connecting one to Mac mini directly to see what happens.

@mac_editor, unfortunately, i'm still using 32 bits app so catalina is not for now. As for the monitor, i did connect one using HDMI directly to the mac mini and the other 2 connected with the EGPU, but same behavior, mac os kind of freeze and then reboot automatically.
