Given a MacBook Air that's working but with dead display and SSD, can I use it as a desktop-only machine with an external monitor and external hard drive?
The guy at the Apple Store Genius Bar this afternoon told me I could install the OS on an external drive and boot from it, but I'm sure even Apple Geniuses sometimes make wrong assumptions?
If it is possible would a USB external drive suffice or would it require a drive that connects to the proprietary connector?
Also if it is possible, is it fairly straightforward?
(I am a technical/computer guy, but not a Mac guy.)
