MacBook is not charging, or booting up

Hi All,

I have got many dead MacBooks 12” retina 2017, and obviously, they all have same issues with a burned USB-C port. Anyone else facing this kind of issue?!?

A common problem across ALL USB-C devices! We also see it on Lightning ports in iPhones and iPads.

The issue is people often use a dirty cable which the grime causes the the power pins to degrade. Sadly, the USB-C interface is a bit fussy as the fiberglass tab is on the socket side unlike Lightning which allows you to just replace the cable Vs the system connector.
