Answer:Apple’s Disk Utility securely erases data from hard drives, and it’s built right in to OS X. If you’re running OS X 10.7 or higher, you do this through Internet Recovery. Restart your Mac and hold down Command + R during the start up process. Don’t let up on those keys until the Apple logo appears. A menu will appear giving you a few choices: Disk Utility, Reinstall OS X, and Restore from Time Machine.
Choose Disk Utility. Choose the HD you want to erase, then click erase. You can choose quick erase or secure erase, depending on your needs.
