Thunderbolt and Random Disconnects SOLVED with OWC Thunderbolt Hub
Thunderbolt is supposed to allow 6 devices per port/bus daisy-chained, but users with more than two devices daisy-chained have almost certainly run into the dirty little secret of Thunderbolt that neither Apple nor Intel will discuss: sporadic random disconnects.
Ever have macOS tell you that a device has disconnected unexpectedly (that you should eject it first?). If it’s on Thunderbolt and you didn’t physically do something, that’s a disconnect bug.
Thunderbolt 4 indirectly addresses this nasty reliabilty problem with support for Thunderbolt hubs, also a boon for Macs with only two Thunderbolt ports.
