Is it possible to use Migration Assistant over USB? To migrate from 13-inch MacBook Air (mid 2009), which has a single USB 2 (480 MBit/s) port, into a new MacBook Pro (mid 2017) 2.13GHz Core 2 Duo/2GB/128GB SSD, which has two Thunderbolt 3 ports. If possible, how to do it? Because I think that Target Disk Mode (TDM) does not work on the MacBook Air described above (since it only has a USB port; it does not have Thunderbolt or FireWire ports). If possible, I do not want to use WiFi (it is utterly slow and unreliable) or Ethernet (cumbersome and also quite slow and unrealiable sometimes). Thanks!
