USB C Dead, USB Accessories Disabled.
Hi, my 15” MacBook Pro 2018 Touch Bar system has a problem
One of the 4 USB C's has failed! I did an update to Catalina it was not fixed. I have tried I believe correctly resetting NVRAM / SMC but no success... The system passed the diagnostic test. I have tried safe boot again nothing.
When I try to plug in something it pops this message (in Mojave I have never received a pop like this)
USB Accessories Disabled
Unplug the accessory using too much power to re-enable USB devices
After some experimentation.
Connect first to the Dell monitor, cable -> charges. Then I connect also the Apple charger to the problematic USB C port it charges.
I unplug the Dell monitor cable, then it charges from the problematic USB C port (but I’m not sure if it works the percentage drops, but if I unplug it the display dims down…)
I tried while plugged in and powered the hunt to SMC reset but I failed.
Somehow I believe that something with electric circuits, electricity from my Displays USB C charge has been evolved in this case. My display is a Dell 3219Q USB C.
Any ideas what to try?
