  3. 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.
  4. Choose Apple menu () > Software Update to check for the latest Apple software using the Mac App Store, including this update.
  5. 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.
