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:
- Under the Apple to System Preferences
- Click on Security
- Set a master password
NOTE: This master password does not have to be the same as your network/e-mail password.
- Also have a checkmark in Require password to wake this computer sleep or screen saver
You can click the lock symbol to prevent changes.
