Increasing Your Mac’s Security
Whether these settings are important to you depends on how vulnerable your Mac is to snoopy intruders. If your computer is in a dorm room or an open office, or if it’s a laptop, you’ll probably want to put at least some of these measures in place to ensure that unauthorized people can’t use it.
Choose Apple menu, System Preferences.
Click the Security & Privacy button to see your choices.
- Click the General button, and then click the Require password check box to make sure that only you can wake up the computer when it’s sleeping.
Click the check boxes next to the other options to turn them on or off.
