Im new to the thunderbolt and USB-C stuff. My understanding is while they are the same there are some small differences in power and speed. I received my Mac mini today and while watching videos on the Mac mini wanted to take notes on the iPad Pro. It came with a USB-C charging cable. I plugged it into both ports to find it would not charge and also was not recognizing the iPad in iTunes. Luckily I had an Anker Poweline+ C 6ft cable that does work. Do I need a dedicated Thunderbolt cable or is it more of a port issue?
