If you’re on a Mac with recent macOS release such as Sierra or El Capitan, then Apple is defaulting to try and automatically downloading the 5GB installer for macOS High Sierra in the background to your computer. When the download completes, the Mac then sends you a notification suggesting that High Sierra is ready to install.

The notification only having two options; “Install” and “Details”. Some users may find this convenient to automatically download a major software update and casually suggest to be install it onto a Mac, but other may be less than excited about this behavior, particularly if you’re not yet ready to install macOS High Sierra on a Mac. Here's how to prevent from it.

1. Go to the  Apple menu and choose “System Preferences”
2. Go to the “App Store” panel
3. Uncheck the box next to “Download newly available updates in the background”
4. You can also uncheck the “Install macOS updates” box if you want to continue to download updates but not install them right away.

By doing this, it should prevent macOS Sierra or Mac OS X El Capitan from downloading “Install macOS High Sierra” file onto your Mac into the Applications folder, and prevent from sending the notification that it’s ready to install. Whichever way you go with macOS updates, user still can easily change the settings in System Preferences if you change your mind later on.
