Migration assistant hangs

Old MacBook connected to new Mac mini on WiFi and internet cable. Starting migration assistant on Mac mini hangs OSX requiring power reset to recover. (I see lots of others reports of this. ) Any help if I get a FireWire connection and set the old MacBook to delete target mode?

Mac mini 2018 or later

If I understand correctly, you are now wanting to migrate from the MacBook to the headless Mac Mini after the fact?


If so and if you could, it would ultimately give you 2 accounts on the headless Mac MIni. The one you initially setup and a second one from the MacBook.


Personally I only see 1 good option and two that will only allow you to manually move your User Data to the Mac Mini.

  1. Start over! Use a Keyboard, Mouse and Display, completely erase the Mac Mini and do a proper Migration from your TM backup.
  2. Manually move your User Data over to the Mac Mini using an external drive, flashdrive or perhaps (depending on the size) over to the Mac Mini via Ethernet.
  3. Pay for an expensive FireWire adapter and hope that you can use Target Disk Mode to connect the Macbook and Mac Mini together and again, manually move your User Data over from the MacBook over to the Mac Mini.

You understand correctly. I would be fine with two personal accounts; the one I used to setup the mini and my old one from the MacBook. Also (although it didn't occur to me until very recently), I would love to be able to move my old (current) Time Machine hard disk to the mini, to preserve my disk history since 2010 or so, when I first started using Time Machine. In fact, I'd be willing to clear the mini, and reinitialize it with borrowed peripherals. Do you think Migration Assistance would work in that case with my 2007 MacBook?
