OS X Mountain Lion: Keep your information safe

Keep your information safe

To protect your computer, perform regular backups, use secure passwords, and install software updates.

Perform regular backups

You should always back up. That way, if something happens to your computer or you accidentally delete something, you can easily recover your files.

The easiest way to back up is to set up Time Machine, which backs up your entire computer automatically every day.

Time Machine overview

Besides Time Machine, you have several other choices for backing up your important files, including burning CDs and DVDs, or copying files onto an external drive.

Alternatives for backing up your Mac

Limit unwanted access to your information

OS X has a number of features to help keep the information on your Mac safe. If you have multiple people using the Mac, you should set up individual users, so that one person can’t modify the files needed by another. For more information about setting up users, see this help topic:

If you want to check for software updates immediately, choose Apple menu > Software Update.
