Summary

Starting up the Mac is as easy as pressing the power button, but more sophisticated capabilities exist when you need them, such as the ability to start up from different disks and to require login so only authorized users can access the Mac. This combination of simplicity and rich capabilities extends to the Mac's option to go to sleep, restart, and shut down, as well as to switch among authorized users.

OS X Mountain Lion can remember what windows were open when you log out, restart, or shut down and automatically reopen them when you next log in or start the Mac.
