So i'll be needing to replace my Macbook's (retina, 13", late 2012) battery tomorrow. (cells have become a bit bloated)
Regardless of whether i break the machine doing so or not, i also wanna do a complete format and reinstall of MacOS Sierra.
Seeing how all my personal documents are either stored in dropbox, or in my documents or desktop (which are stored in iCloud drive), and my photos are stored in my iCloud photo library - there's no need to really make a / restore from an actual 'backup', is there?
(same goes for my emails, icloud keychain, etc.)
I'd like to have as fresh of a system as possible.
