update to macOS Catalina 10.15.4

Open the Software Update preferences panel or see How to upgrade to macOS Catalina.

Before You Update or Upgrade macOS

1. Fix any problems before upgrading.
2. Run First Aid in Disk Utility while booted from your Recovery HD.
3. Backup. Make a bootable clone using CarbonCopy Cloner or use TimeMachine.
4. Be sure your startup disk has 18-20GB of free space during the installation.
5. Upgrade third-party software for compatibility. See App Compatibility Table - RoaringApps. If you have mission critical software, then DO NOT upgrade until you know that software is compatible with the version of macOS you are about to install.
6. Disconnect all third-party peripherals.
7. Download the installer which will be in the Applications folder. Quit the installer after it opens, then make a copy of the installer and save it in the Downloads folder. The one in the Applications folder will be deleted after a successful installation.
8. The download is large, anywhere between 5 and 9GBs. It takes time to complete. Be patient.
9. Double-click on the installer in the Applications folder. Click on the start button to begin the installation.

You're welcome. It's fine to ask questions. It's just for one thing this is about being able to update to 10.15.4, and it's marked solved so you're less likely to have your question answered.

At any rate, try deleting this file to remove the badge.

~/Library/Preferences/com.apple.preferences.softwareupdate.plist

type in your user password and hit return. You won't see any feedback as you type.

You're very welcome.

I installed the update for Catalina 10.15.4 and then problems started. Is there any way to remove the red circle on systems preferences/software update? Chrome is also not working properly.

You should start your own threads. Your issues have nothing to do with this one.

Ok thank you for the tip dialabrain. It's my first time here. I will figure it out eventually.

Mac air os 10.15.5 After clicking update, I get notice to restart. The update will not take. I still have notice to update.

I've run this command but the nothing changed. It still doesn't offer an update.
