Easy: Mac OS X Recovery Mode Key Combination
Today’s Mac computers have a built in feature called recovery mode which allows you to start your Mac computer on a separate boot partition on your hard drive and restore from Time Machine backup, reinstall Mac OS, or use disk utility. If your Mac does not have the built in recovery mode, you can attempt to boot into recovery mode over the Internet (see below). Ensure you are running the latest version of Mac OS X supported for your Mac machine in order to be able to access Recovery Mode.
Mac OS X recovery mode is useful for troubleshooting issues with your Mac computer. Booting into recovery mode allows you to use Disk Utility and repair your primary Mac partition for disk issues (by default, you cannot repair your primary Mac OS X volume while you are booted into it, this feature is greyed out in Disk Utility). Finally, recovery mode allows you to easily install the latest version of Mac OS X compatible on your Mac from the Internet.
Boot into Built-In Recovery Mode
