migration assistant unable to connect to other mac

Hey mklester,

Are both Macs up-to-date? If you're not sure, check for updates by following the steps below or reviewing them here: Update macOS on Mac.

"Before installing new software, it's a good idea to back up your Mac.

1. From the Apple menu  in the corner of your screen:

• Choose System Settings. Then click General in the sidebar, and Software Update on the right.
• Or choose System Preferences. Then click Software Update.

2 If Software Update finds new software, click the Update Now or Upgrade Now button to install it.

3 Enter your administrator password, if asked. During installation, your Mac might restart, and you might see a progress bar or blank screen several times.

If Software Update says that your Mac is up to date, then no new software is currently available for your Mac model. Software Update shows only updates and upgrades that are compatible with your Mac."

If the Macs are up-to-date or updating didn't help, providing more details such as error messages may help you get more answers.

Take care.

Just to be sure you understand, you have to be running Migration Assistant (whatever version is on each Mac) on BOTH Macs.
