Migration assistant fails since it says it can’t connect to my old iMac. Diagnose? Workaround?
I don’t understand why Migration Assistant can’t connect my old iMac and my new iMac. They are both connected to the same network with WiFi. Old iMac is mid 2011 running Mac OS High Sierra 10.13.6. New iMac is 21.5” just bought running High Sierra 10.14.5. How do I troubleshoot this and get all my data transferred to the new iMac? No compatible cable to physically connect them.
