Hello all, I have a iMac 27 Late 2013 with Thunderbolt 1 ports and USB 3.0. When I hooked up my new My Passport Ultra for Mac 4TB using the included USB C-USB A connector, I am told it will take 22 hours (probably more to back up my 1.7TB of data. Is there a way to connect my Thunderbolt port (it is the original Thunderbolt, not TB 2 or 3) to the USB C on Passport to improve transfer time? I have tried to figure this out on line but everything seems to be based on TB 2 or 3. Thanks for any help.
