Locking a Macintosh Screen

When you step away from your Macintosh, it is advisable to have the screen locked, so that the Mac prompts the next user for a password to show the desktop after a screensaver has been on, or after a sleep period. This assures user security to files and open programs.

A. To apply this locking process for Mac OSX:

  1. Under the Apple to System Preferences
  2. Click on Security
  3. Set a master password
    NOTE: This master password does not have to be the same as your network/e-mail password.
  4. Also have a checkmark in Require password to wake this computer sleep or screen saver

You can click the lock symbol to prevent changes.
