Problem using Migration Assistant
I have set up my new mac mini as a completely new system running Big Sur 11.5.2 I am now trying to use Migration Assistant to transfer some specific settings (an extensive table of Keyboard Text shortcuts) from my old 2011 iMac. That is limited to running High Sierra 10.13.6. Hence my long overdue new system.
WiFI connection did not work. I have just tried Gigabit Ethernet cable connection. Migration Assistant is locked into a "Looking for Other Sources" Loop. I don't know why, or how to fix it, if it is fixable.
Help required. Relevant advice welcome
