It appears that there are now many user reports of Apple Silicon-based M1 MacBook Pro and MacBook Air machines failing after being connected to USB-C hubs with USB-C power delivery (that is, hubs which simultaneously supply power to the Mac).
The symptoms reported are a completely dead MacBook that will no longer power on and shows no signs of life. Several users report a clicking or tapping sound. It seems to happen at the time the power cable is plugged in or unplugged, or when the Mac is allowed to sleep with the hub connected. The only remedy is to return the MacBook to Apple for repair or exchange.
At the time of writing this article, there have been no reported cases of dead M1 MacBooks when using Apple’s own USB-C Digital AV Multiport Adapter, or when using Thunderbolt 3 docks.
