How to update your Mac

Before updating, it's a good idea to back up up your Mac. Then use the Mac App Store to install the update.

Some updates become available only after installing other updates. Install all available updates, and allow installation to complete without interruption. You can also get this update from the Apple Support Downloads site. You might have unexpected results if third-party OS X modifications have been installed, or you modified OS X in other ways.
