Hey what's up everyone, I was wondering if anyone has a solution to this. So I have a new MacBook and want to transfer all the data from my iMac to the MacBook so that they are pretty much duplicate machines. I have migration assistant running now over wifi and it says it going to take 84 hours. I bought a usb c to usb a connected so I could hook up the back up HDD that I use for time machine up to it, but I'm afraid the batter would run out before it completed the transfer because I can't charge and use the usb at the same time. Also the multifunction dongle for charging and the usb because it's not for sale yet. This is making me second my purchase because I can see this being a problem down the road.
