Hi everyone,

I installed the latest security Update yesterday. It looks like this update is an epic fail - may be only for me?

I use a Razer Core X with a RX590 graphic card and the MacMini 2018. In the last couple of month, everything was running fine. Then there is that big Update and i can no longer boot with an enabled EGPU. If i boot with an enabled EGPU on Win 10, then there is a crash right before the login screen. Same thing for OS X. I don't even reach the login screen.

 

When I boot the OS X with disabled EGPU, then I can start it later and can at least use it. If I boot Win 10 with disabled EGPU and switch it on later, then Win 10 needs a reboot before the EGPU can be used.

The point is: I can no longer use Win 10 with EGPU. I can use an EGPU with OS X but never when I enable the EGPU when the Macmini is booting.

Does anyone have similar troubles? Any Idea how this Problem can be fixed?

Steps I did so fare:
Reset SCM
Reset PRAM/SMC

Best regards, Gandalf

I am installing this now and it seems to have ruined my egpu boot in MacOS 10.14.6.  Come on Apple!

Hi there, 

I read that you already did that. But here I found thread that the resetting of NVRAM did work. Here is the link how they manage it. https://discussions.apple.com/thread/250934910

Please try it and let us know if it works for you.

Thank you, that worked.  Is there an easy way to rollback this update?  I have time machine backups.

It doesn't work 😥 . It makes no difference if I reset the NVRAM with EGPU switched on or off.

 

@hornedfrog

Try it and report. I'm not sure if it will work. I read somewhere (at least i think i did), that this is a problem with the firmwareupdate of the MacMini. But i might be wrong.

Will try, thank you.  Can the update be rolled back with time machine or another way?

Was not able to rollback.  Problem persists.  Did this update firmware?

The security update updated the mini firmware the NVRAM reset only works once then it goes back

 

This is known to apple and logger in the developer community until then workarounds only

Hi 

This is the solution that so far has made me boot a couple of times without problems

Issue occurs if you boot with filevault on or if you did a system update with the eGPU connected or in recovery mode

To restore normal function:

1. Shutdown the system

2. Turn off the eGPU

3. Retrieve an HDMI cable and connect the mini to the display with this cable

4. Boot and reset the NVRAM with command+option+P+R

5. Complete login

6. Disconnect HDMI cable

7. Turn on the eGPU

8. Reboot

The reboot will not show anymore the apple and will only give some purple lines just before the login screen

Thank you.  I don't use FileVault.  I am hoping for a fix from Apple, this worked only once in my setup.
