  5. Restart your computer.

Preventing High Sierra Automatic Downloads

Now that you’ve deleted the file, you can prevent future downloads by going to System Preferences > App Store and unchecking Download newly available updates in the background.

This of course means that all app updates will not be automatically downloaded in the background, not just OS updates, so if you like to keep your apps up to date, you’ll have to update them manually.

If you prefer to keep automatic downloads turned on, you can make a duplicate copy of a small application on your computer and rename it Install macOS High Sierra. (The name has to be identical to the original High Sierra file.)

Once you’ve renamed it, right click the icon and select Get info. Under the General tab, make sure that Locked is checked.

    This is awesome. Used it for Mojave, but same difference. I use Music Software I don't want to update and make useless so I have been going nuts with this "nag screen" reminding me of Windows in the 1990s! What happened Mac. Thanks for saving me 6GB, too!!! Deleted that badboy that was already downloaded!!!
