As the MacBook was Apple's first USB-C device and is roughly 1.5 years on the market, how did the single USB-C port hold up? USB-C has a pretty tight fit and the plug stays locked so it doesn't slip out and loses connection, but does it loosen with time? I've discovered that both my Nexus 5X and ntbMBP were basically too tight at the beginning but became just right after a few days. I'm using the 5X for 9 months now. Only charging every other day isn't quite a stress test for the port, so it doesn't say much about durability. So, how are your MacBook's ports doing? Power users with lots of unplugging and early adopters would be perfect.
