How can I backup my mac to an External HD but then return it to factory settings?
I recently got a Macbook Pro from my relative who lives with me but he still has all of his pictures, music, documents, etc. on it. He gave me his "Mac Backup" 500GB TimeMachine enabled external hard drive to save everything to it completely for him. The EHD, has 180 GB left, is Mac OS X Extended (journaled) and obviously already has some previous Time Machine Backups. How can I save everything that is still on the MBP now to the EHD? I then want to know how I can turn the Mac to factory settings so I can use it for my own personal things (school, music, programming etc.). Also, my relative says since he would no longer have a macintosh computer, so he would probably not be able to access anything from the hard drive on his Windows 7 computers. Is this true, and would he then just have to just plug his EHD into my MBP anytime he wants to access his media? I would appreciate if any would please recommend the best way I could do this. Thanks in advance.
MacBook Pro, Mac OS X (10.6.8)
