I do need to do this wireless as I do not have a thunderbolt adaptor.
Otherwise, I really did look into everything possible - did all the rechecks 3 times around -no firewall, no anti-virus, nothing to stand in the way - pc checks clean...
After a night's sleep, today is even more hopeless, yesterday I got as far as having a number on both screens, now before the connection has a chance (while the mac still looks for the pc), the migration program in the pc freezes up with the notice "an error occurred while preparing your information for transfer". I've tried starting up the Mac MigAss first, the pc first, the two as simultaneously as possible. I've cleaned, removed and reinstalled the MigAss on the pc several times. No results to the better.
Apple promises that this should work, but I've found a couple other comments to the same effect. Is a cable really the answer? (Outside of the money the adapter costs, I don't need it for anything else.) It doesn't seem likely...but? After several hours in vain, I really would like to know if I'm wasting my time.
