thunderbolt/usb-c ports don't work

Just updated my macbook pro 14" 2021 to Ventura and now all 3 thunderbolt ports don't work. Tried everything (like trust all accesories) but still no solution. Suggestions online tell me I have to wait for an bugfix/ new update. How is this possible?

Anyone know how to fix this?

MacBook, macOS 10.13

Two things to try.


  • restart in safe mode followed by a normal startup

  • reset the SMC three or four times in a row.
