MobileMe Sync: User moved via Migration Assistant does not register computer for syncing
Symptoms
If you use the Migration Assistant to migrate/copy a user account to Mac OS X 10.5, you will still need to register for MobileMe Syncing.
If you check the box to Synchronize with MobileMe, you may receive an alert that another computer is already registered with the same name.
Products Affected
Mac OS X 10.5, .Mac Sync, MobileMe
Resolution
This is expected. If you migrated the user from a computer that you still want to sync with via MobileMe, click "Enter another name" if you receive an alert.
If you no longer are using the computer you migrated from for Sync, you can safely click "Use same name".
