I've had my MacBook 11' 2015 Air since July 2016 and my iPhone 7 since April 2017, and my phone never had any issues charging on my Mac. I'm not sure when it started, but at some point both USB ports in my MacBook won't charge my iPhone 7, it just keeps going from charging to not charging very rapidly which only makes it even more annoying and frustrating.
I've tried multiple different cords, reset my iPhone, shut down and reset the NVRAM on my Mac, force quit USBD, deleted (and later reinstalled) the Thunderbridge network.
I'm far from a computer person, so I am very frustrated and currently want to smash both devices :-). I've googled it plenty, but hopefully I can get some new results that actually work.
If you have any solutions, please help me out here and explain it clearly to someone who knows how to operate a computer, but has little knowledge of coding or most of the inner workings of a computer.
