Great article but misses a critical piece: where, exactly, do you purchase replacement USB C ports? Without that information, this article is almost useless.
There is a link to buy the USB-C board under “Parts” at the top of the article.
Hi! Is it really necessary to disconnect almost the entire board to just replace 1 piece? or is this guide multiple fixes within one? I just need to replace the USB C left port, thats it. Thank you!
If I'm not mistaken, Apple's design hides the USB-C port fasteners underneath the mainboard, requiring disconnection of almost every cable on the mainboard and removal of the mainboard before you can access any USB-C ports. Apple really didn't design their devices with ease of repair in mind, and unfortunately this means almost any DIY repair of a modern Macbook will be quite involved.
