Hi guys,

I have Mac Mini 2018 running Catalina 10.15.6 with Blackmagic eGPU Pro and when eGPU is connected to Mac, Mac won't sleep. When I soft-disconnect the eGPU via Thunderbolt menu, it doesn't help. When I unplug the Thunderbolt cable, Mac properly goes to sleep after specified period of time so it is apparently related to eGPU. I can have eGPU headless with no devices attached to it and monitor attached to Mac, or I can have monitor attached to eGPU, it doesn't make a difference, it behaves the same way, blocks the sleep.

pmset -g does not show anything obvious, just occasional (sleep prevented by sharingd), which pops up even when eGPU is disconnected and Mac falls asleep successfully.

pmset -g assertions shows some Thunderbolt assertions, but I guess those are there always when Thunderbolt is attached:

It's kinda funny amidst the complaints about Macs won't waking up with eGPU. Well, my won't sleep :-). 

Just wondering if anyone experienced something similar and I'd particularly like to hear from guys with Blackmagic (Pro and non-Pro), whether their Macs sleep well with this eGPU attached.

Thx!
