Hi, Just bought a MacBook and I love it, much better than my old Windows laptop in terms of performance, despite the lower spec. However, the main reason for purchasing was that the 13in is small enough to carry about, since I'm training to become a teacher this coming academic year and will be using my MacBook for presentations and all that. I just wanted to know, if I create a new user account can the files from my other account be accessed. Basically, although I will be using the MacBook as a teaching tool, it will also be my personal laptop and the last thing I want is a load of teens rumaging through my mail, photos, contacts etc. I only ask because with my Windows laptop, you had to turn something on to prevent other users accessing my files and wondered if it was the same on Mac. Thanks!
