I have been backing up my old macbook pro to an external drive and have run many successfully backups using time machine. Recently, i purchased a new macbook pro and intend on restoring from a time machine backup on my external drive. For some reason or another, i chose not to restore from time machine backup in the initial start up of the system. Is there a way to do what i want to now? Or am i required to reinstall the OS again? Thanks.
