Use this guide to replace the back Thunderbolt 4 ports in your Mac Studio (2023).
Note: You can only replace the two inner and two outer ports (or all four), as they're connected by flex cables. You can't replace individual ports.
If you're having trouble connecting devices to the back Thunderbolt 4 ports or cables fit loosely in them, it may be time to replace the ports.
Before starting this repair, read through Apple's troubleshooting article and try the software and cleaning solutions that don't require taking your device apart. Make sure to test your cables with a different device to confirm the issue is with one of the ports, and not the cables themselves.
