Hi, I have given my macbook air 2012 to my eldest daughter. I have still have my account on it and hers. The macbook is now running out of disk space and I want to set it up clean for her to use. What I need help with is this. I want to do a fresh install of el capitan for her. If I factory reset the air, its currently on yosemite, can I install el capitan and then load all her files, photos, apps and stuff from a time machine backup? Thanks in advice for any help!
