OS X Mavericks: Reinstall OS X

Reinstall OS X

Use the built-in recovery disk to reinstall OS X while keeping your files and user settings intact.

Important: You must be connected to the Internet to reinstall OS X.
  1. Choose Apple menu > Restart. Once your Mac restarts (and the gray screen appears), hold down the Command (⌘) and R keys.
  2. If you’re not connected to the Internet, choose a network from the Wi-Fi menu (in the top-right corner of the screen).
  3. Select Reinstall OS X, then click Continue.
  4. Follow the onscreen instructions. In the pane where you select a disk, select your current OS X disk (in most cases, it’s the only one available).
