I just ordered a new 27" Late 2015 iMac. I'll be moving my data from a 27" mid-2010 iMac. What's the recommended medium for the migration?
I know how to use Migration Assistant, but the old iMac has Firewire (no Thunderbolt) and the new iMac has Thunderbolt (no FireWire).
Is an Ethernet cable my best bet? It'll be faster than wireless, but I suspect still pretty slow.
