Question

I have a new iMac.  I'm using Migration Assistant to transfer files.  My old computer spontaneously shut down.  I restarted it and am trying to use Migration Asst again, but each computer is waiting on input from the other one.  What do I do?

Answer 1

Let me see if I've gotten this right! You want to remove an account from BOTH machines? Do this for your new machine first, then for the other.
Click the Apple logo on the top left of the screen, System Preferences, Users and Groups (under Systems), unlock the lock in the window if its locked (you need to know the password), select the user that you wish to remove, and click the - sign next to the + sign for Login options. A window will pop up with some options. Select Delete this user and securely, and click 'Delete user'.
After this, do an update from the App Store.
Thats all there is to it.
For the other machine repeat the process except for one thing. Before you delete the user in this case YOU, you will have to give Administrator priviledges to your son bu checking the box 'Allow user to administer this computer'.
Do NOT do anything from Finder ... if you dont know how to fix the consequences of the problems caused.
There is no need to unauthorize your iTunes account on your new machine. Do it on the old machine though.
