Migration Assistant "unable to connect" both Macs are on and connected to same network

Hello silverfit4life,

Thank you for using Apple Support Communities. Sounds like you're getting prompted an error message when trying to migrate your data between two Macs. Allow us to assist. The resource you came from does list some settings and steps you should check prior to attempting this data migration: Move content to a new Mac - Apple Support

-Update the software on both computers, if possible.

-Make sure that both computers have Wi-Fi turned on and are near each other. If either of them is using OS X El Capitan or earlier, they should also be on the same Wi-Fi network.

-If you installed antivirus or firewall software, turn that software off until you're done.

Sometimes certain routers do come with built-in firewalls. You might have to temporarily disable those to see if that is preventing your Macs from communicating with each other. You can also test this issue in safe mode. This step can help isolate possible software related issues: How to use safe mode on your Mac - Apple Support
