You may experience unexpected results if you have third-party system software modiﬁcations installed, or if you've modiﬁed the operating system through other means. Choose Apple menu () > Software Updateto check for the latest Apple software using the Mac App Store, including this update. Other software updates available for your computer may appear, which you should install. Note that an update's size may vary from computer to computer when installed using Software Update. Also, some updates must be installed prior to others.

You can also download the manual update installer. This is a useful option when you need to update multiple computers, but only want to download the update once. Standalone installers are available from Apple Support Downloads.
