Do you have multiple user accounts on your Mac? Perhaps you have separate accounts for personal and for professional use, or a Guest account for others to use? In that case, you may be interested in taking advantage of a nifty hidden feature called Fast User Switching.
As the name suggests, Fast User Switching it allows you to switch between Mac user accounts considerably faster. This is also great for family Macs, where multiple user accounts use the same machine. Typically, in order to switch to a different user account on your Mac, you have to manually sign out and log back in from the Apple menu. With Fast User Switching, it feels like you’re toggling between different accounts. The feature combines the logout and login actions using a single click.
