When my Macbook Pro is on and I am working if I plug in power or any USB C device the system freezes and then shut down. Aft this I have to unplug the device and sometimes it will power back up but most of the time it will not. I have tried clearing the SMC and that will sometimes get it to power back on. Once back on and I plug something in again it will do the same thing.
MacBook Pro 15″, macOS 13.5
What ports did you order? Are you planning on opening the Mac and doing the work yourself? If all ports don't work, I doubt the issue is hardware. Before I cracked the case, I'd reinstall the OS. But that's just me. I've opening my 2016 MBP several times to replace the SSD, and working in those tiny spaces is not all that comforting.
You can test your hardware yourself: Use Apple Diagnostics to test your Mac - Apple Support
You might want to test the USB devices on a different Mac, or even a Windows computer.
Yes, I have, I have tried multiple power adapters and cables along with multiple USB C SSDs and Card readers. My thinking is bad ports but it is strange that all four would be bad.
I have ordered replacement ports in hopes that it fixes the issues but wanted to ask if others have had this issue and if it could be something else.
Thanks for the answers and advice ku4hx,
Yes it is all four ports and I ordered two new USB-C boards from iFixit.
I just reinstalled the OS (Ventura) and that did not seem to help. Once I plug in power or another USB-C device the system will freeze and shutdown. I then have to remove the device/power and then it will power back on.
These devices all work fine on another MacBook Pro and MacBook Air.
I have ran the hardware test and it says everything has passed but I think I will run it again after the fresh OS install.
Have you given any thought to the possibility the USB device may be defective?
