You can hide the macOS Sierra upgrade banner in Mac App Store

If you’re still running an old version of macOS, you’re likely be annoyed by the big macOS Sierra banner that appears on the top of the “Updates” tab of the Mac App Store app. This is especially true for those with older Mac which technically is not able to upgrade to macOS Sierra. Fortunately you can easily get rid of the banner. Just right click on the banner and select the menu option “Hide Update”. The big banner will disappear.
