Migration assistant is not working. Software on both the old Mac and the new one is up to date. Firewalls are switched off on both as well. Error message shows saying that they are unable to connect using migration assistant.

Hi Nowonami,

The Move content to a new Mac resource you're posting from will have the best information regarding this topic. If you're still having trouble with things you'll want to reach out to Apple Support directly here: Get Support

Take care.

The next thing I would look at is the connection between the two computers. I recommend that you use a wired connection with a USB cable, not Wi-Fi or a network. They are too slow and can cause corruption of your data.

I am using a cable and adapter and it still won't work. I have tried it over and over starting on the new computer and also starting on the old computer. I want to move my apps and Apple.com says to use migration assistant to do it but it always says Unable to Connect to the older Mac even though it clearly sees it because it is on the screen.

Like Nowonami the software is up-to-date on Monterey 12.6.1 on both machines and they are on the same network.

When encountering a problem such as this it is necessary to go through a process to eliminate some potential problems as noted above. The next thing I would do is to use a different cable to eliminate it as the culprit. Occasionally a cable or an adapter can be the problem. The only way to know s to replace both of them. Incidentally, newer cables are available which do not require adapters. They have the newer connecters needed.

I chatted w Apple support and figured out that Norton Security was not off entirely. Deleted it under Network and then uninstalled the app. Also, I thought my brand new Mac was up to date on software but alas, it wasn’t. Installed Ventura and then Migration Assistant worked. Magically.
