Scenario
You're using Migration Assistant to transfer your account named "Andre" from your current MacBook Pro to your new iMac. The iMac is already configured with an account also named "Andre."
What happens with Migration Assistant if the account names are the same on both Mac computers?
To view the installer log during the installation, press Command-L on your keyboard. A new window will open showing the log messages. You can press Command-3 to show all messages, or Command-4 to show errors and progress messages only.
