To install the latest software updates on your Mac computer please follow these steps.
Click on the Apple () menu in the upper left hand corner and then select the Software Update menu option.
Make sure you’re logged into the correct i Tunes account for the specific update, and hit the dark gray Update button when you’re ready.
The update will still show up in your Updates tab in the App Store, but it will just start over from the beginning, unlike Pause, which will resume wherever it was in the process of downloading the update.
This could come in handy if you just want to quit an update for any reason, but don’t want to resume it in the near future.
If you want to cancel the download completely, simply hold down the Option key, which will change the Pause button into a Cancel button.
Click on Cancel and the update will stop downloading, no matter where it is in the process (unless it says Installing; in which case, you’re out of luck).
