2012 Mac Mini, 4 external HDDs (all USB) connected. 2 USB drives, one 2-bay USB drive dock. The mini periodically needs to be rebooted, and for whatever reason it just won’t do so if the USB drive dock is connected.
And by “won’t boot” I mean no startup chime, completely black screen, no errors, no nothing. It wouldn’t be a big deal except this Mini is in a rather inconvenient place.
Can anybody think of a reason for this? None of the drives in the dock have the “bootable” flag, if that matters at all.
