So, $660-plus later of getting my data retrieved, a new battery installed, an SSD installed and an upgrade to High Sierra on my mid-2010 MacBook Pro 15-inch, I have just purchased my first external hard drive. Question: If I use Time Machine and back up all my stuff to the external, what happens if my current laptop crashes and I can't access anything on it, so I buy a new Mac of some sort and want to put all of the backed up stuff into that? Can it be done? A Mac friend user said it can't be done, it can only be re-inputted to the original machine where it all came off of. If that is true, and all I really need are my documents and photos and some other downloads, then why not just put it all on a flash drive? What's the point of the external? Thanks for your help.
