I am sure there is a way but I haven't found it. I can connect my phone to my MBP via USB but it won't show up as a "drive" for me to move files across.
Ha, I was just going to post that I found a somewhat inelegant solution. My phone supports USB OTG (on the go), so I just got an OTG cable and a 64GB thumb drive. When I connect, the phone recognizes it, and I just move files over. Then it's just a matter of plugging the thumb drive into the Mac. Although not the simplest approach, it did save me a lot of time. I haven't tried to move large files
from the Mac to the phone, but I assume that'd work, too.
