want to transfer everything/make a clone of ur mba or just some things?
use time machine?
Connect them via ethernet, go into the HDD, on the left click the other Mac, log in with that Mac's username and password, and drag everything across.
When you start up a brand new mac you get the possibility to use the migration manager to transfer all your data. Just follow the guide during the initial startup and have an ethernet cable ready to connect your old mac to your new.
so i gotta get a ethnet adapter? can i just do it through an usb?
thx again
Don't Macbook Airs have ethernet? Lol.
Open Applications/Utilities/Migration Assistant to migrate user info, applications and/or most systems settings over Airport. No cables.
Since both machines use Draft-N wireless, your transfer speeds should be zippy enough.
EDIT: unless this is overkill. In which case, use Create Network under the airport icon at the top of your screen.
