OS X Mountain Lion: 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.
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.
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:
Use secure passwords to prevent unauthorized access. For more information about passwords, see this help topic:
