What is the right way to disconnect/reconnect the e-GPU from/to the Mac mini
I'm using my e-GPU now for half a year and it's fantastic. Disconnecting from the e-GPU goes OK but reconnecting again however is quite the opposite, it's giving me headaches.
This is how I disconnect.
1-Click the e-GPU icon in the menubar and choose “Disconnect AMD Radeon RX Vega 56”. The monitor goes black
2-Disconnect the Displayport monitor cable from the e-GPU and the monitor
3-Disconnect the Thunderbolt cable from the Mac
4-Connect monitor and Mac mini with the HDMI cable, the desktop is showing again
Now I wanted to reboot in Safe Mode because I had to change the security settings of the T2 chip and I had some problems and I wanted macOS Mojave to verify the startup disk and eventually repair directory issues. But after disconnecting all startup key combinations did not work anymore. I had to reset PRAM/NVRAM to be able to boot in safe mode or use other startup key combinations.
1-Shut down the Mac
2-Disconnect the HDMI cable from the Mac and the monitor
3-Connect monitor and e-GPU with the displayport cable
4-Connect the e-GPU to the Mac with the Thunderbolt cable
5-Start Mac mini
After this I had all sorts problems with the resolution. The menubar and Dock didn’t show up and I had to use the Command+Option+Space combination to get anything done end shut down. Or the monitor is showing dotted and coloured horizontal stripes. After a few attempts suddenly the Mac booted with no problems
So I wonder what I’m doing the wrong and what are the right procedures to disconnect/reconnect the e-GPU from/to the Mac.

You're not doing anything wrong. We have to keep in mind Apple has never supported this many third-party hardware components before. Yes, there are only enclosure and GPU but the possible combinations are thousands. It's more challenging on a headless Mac because without any screen output, we can't really tell what the Mac mini is doing. It will take time for the firmware of the 2018 Mac mini to get better. In the meantime observe which actions cause issues and which actions work well.
