Yesterday all three rear USB3 Ports on my Mac Mini M4 stop working. No connection No power.
The system reports shows the the three USB3.1 Buses are present but no connected devices when anything is plugged in.
The two front USB ports are still working fine. Anybody out there got any solutions. Thank you.
Mac mini, macOS 15.6
Sounds like the rear TB/USB-C port protection has tripped to protect the Mac mini.
This can be caused by a bad cable, a bad device or by overloading a hub.
Disconnect everything from the rear TB/USB-C ports and restart the Mac mini.
If that doesn't help, startup in Safe Mode followed by a normal restart.

Then test each of your cables and devices one at a time.
