migration assistant does not find other computer
I am attempting to transfer photo albums from an iMac to a MacBook Air. I have the Migration Assistant program running on both systems and they are both side by side on my desk connected to my WiFi network. Although the MacBook Air 'sees' the iMac. The iMac does not 'see' the MacBook. I've restarted both systems several times and made sure they are both connected to the network. Any suggestions would be welcome.
iMac, ipad, iphone
