This short tip teaches you how you can disable Catalina upgrade notifications in the System Preference’s Dock icon and the ‘Upgrade Now’ prompt in the Software Update pane in macOS. You may want to do so, if you are not ready for the upgrade (such as Catalina compatibility issues etc) and if the notifications annoy you. These are just a few reasons why you’d want to stop macOS Catalina from showing up in Software Updates on your Mac. Since you want to disable this, you also would not want to see the red notification bubbles indicating that you have updates available. Do you also want to turn off upgrade notification badges in the dock? Then this article is for you.
