So, my 2016 rMB arrives today. I'll be initially using it for light editing in iMovie for some simple iPhone-shot videos away from home. I already have a Late 2014 Mac mini and Late 2013 Mac Pro. They are connected via Thunderbolt 2, and (most of the time) Target Disk Mode works well when I need to move large files between the two. I understand the included OEM Apple USB-C cable does not support TDM. I plan on getting the $79 Apple HDMI multiport adapter. If I get a proper USB-C to USB-A cable, do you think that TDM will work reliably with my other Macs? Any hands on experience is appreciated.
