Need to Disconnect 2 MacBook Air Laptops
My MacBook Air laptop and my daughter's are connected. Everything she adds to her laptop shows up on mine (and I assume vice versa). I need to upgrade my operating system and my browser, but I can't because
my disk doesn't have enough space. If I delete her information, it's going to disappear from her laptop as well. I know that from prior experience. How can I separate these laptops so that I can delete her information without affecting her laptop?
MacBook Air 13″, macOS 10.12
