Could have been thunderbolt too, of course. I didn't mention the cable type, but thought it would be understood that it was at least a USB-C to USB-C, since both computers have those ports natively. I'm sorry, but am guilty of being terribly wordy and so try to keep things simple and short, but often at the expense of clarity. I tend to use the default admin account only in rare cases. It's not a bad idea to have a second admin account on the new machine. For example, there may be times when only the user files need to be transferred. I like the flexibility that the Migration Assistant offers. That said, there have been many recent posts about an apparent incompatibility of some devices with Monterey. To my mind, given what I understand, I think it the easiest approach would have been to connect the Time Machine disk directly to the new machine. It's possible to disable WiFi on the "new" machine ( networksetup -setairportpower en1 off ( on to enable) from Terminal run from a bootable installer) but I don't think that would have been necessary. If it doesn't, I would try a separate cable from each machine plugged in to an ethernet hub.Īs for disabling the WiFi connection, disabling it on the "old" machine should have been sufficient.


It is fine for connecting a hard drive, a situation where your computer is the "master" and the drive is the "slave", but with two computers, you'd have two "masters" maybe it could be made to work, but is just not worth the effort, given that you can do that over the same ports but with different technology (Thunderbolt).Īs Luis has mentioned, I don't think that you can use a USB cable. You never had the option of putting your mac in Target Disk Mode using USB (of any generation), but you did have that with Firewire, and have now with Thunderbolt.īasically, there are things that USB is not really meant for.

You can't mount the other mac's drive via USB, or share your internet connection via USB but you can create a peer-to-peer network over Thunderbolt, if you know how - that is what the "Network Bridge" service is there for in System Preferences->Network - or over Ethernet. I think that the answer is that USB is not really a network technology (and it is not a peer-to-peer technology, there is always a "master" device). I.E., why would Apple limit Migration Assistant to external disks (ones that would presumably connect with USB-C no less), a network connection, or thunderbolt? I now understand much better what is happening (did happen), but still scratching my head as to why.
