How To Remove MacOS Catalina Notification

(edit: This is satire. I wrote it as a joke. But SOME people got mad because they were looking for a legit tip. A legit tip is in the comments sections, so if you’re just here for that, go ahead and scroll to the comments.)

If you’re like me, you’re going to hang onto MacOS Mojave (10.14), or earlier, for as long as you can, as Catalina (10.15) represents the end of support for legacy 32-bit apps, and I still use a LOT of legacy 32-bit apps.

However, Apple really wants you to upgrade (I don’t know, maybe “rate of adoption” is a metric for which some executive gets a bonus), and therefore if you have the System Preferences icon in your dock, then you have to deal with it constantly reminding you that Catalina will always be there, waiting to break your heart because with it you will no longer be able to use Levelator or Quicktime 7.

This jerk.

There’s no way to actually remove that notification unless you upgrade to Catalina.

Just look at this jerk.

Believe it or not, I actually prefer this method to the Windows method of forced upgrades regardless of whether you want to or not. I get to decide when to lose my computer for 45 minutes as it downloads 8 GB of stuff and restarts multiple times. But until I do that, I still have to stare at this damn notification, so here’s how to get rid of it.

1. Right-click, or control-click (for all you weirdos who haven’t enabled right clicking on your mouse) on the System Preferences icon.

Too much information.

This also allows you to access all of the System Preferences within the dock, which is kind of cool. I actually had no idea this was a thing until now. So this is a BONUS TIP!

2. Select “Options”

I think you can see where this is going.

3. And then select “Remove from Dock”

Get rid of that noise.

And boom! No more notification staring at you in the face every time you open the dock.

Nice and clean.

And if you have dynamic wallpaper enabled, your desktop will also let you know how embarrassingly long it took you to do this. Also, if you have a legit way to remove that notification, I’d love to hear it. Drop your hints in the comments.

    sudo softwareupdate –ignore “macOS Catalina”
    $ defaults write AttentionPrefBundleIDs 0
    $ killall Dock

    I also did this softwareupdate –ignore / defaults write / killall Dock combination and it helps at first moment. unfortunately that red bubble comes back when your mac checking for updates (and I have only security updates selected for automatic install). Even when inside the System Preferences the Catalina-Vista is hidden you have this “1” on the dock icon to remind you. :-( Than you need to repeat the two defaults write and killall Dock commands.

    Mike’s comment wins the day, thanks!
    Note: Just make sure you have the double — before the word ignore in the first statement as my copy and past did not capture it… it should read like this:
    sudo softwareupdate –ignore “macOS Catalina”
    Also remove the $ info if you are copy/pasting this into Terminal.

    sudo softwareupdate –ignore “macOS Catalina”
    defaults write AttentionPrefBundleIDs 0
    killall Dock
