How to Check for Updates on Your Mac
The macOS System Status normally notifies you of any OS updates. However, you can check for updates manually by looking in the App Store.
Here's how to manually check for updates:
Open the App Store. Either select it under the Apple menu or click its icon in the Dock.
At the top of the screen, select Updates.
In macOS Catalina (10.15), the Updates option is on the left side of the screen.
After the system scans complete, Updates either presents a list of available updates or states that No Updates Available.
Choose Update All to install all listed updates, or choose Update to install select patches and apps.
You may be prompted to enter your Apple ID and Password. Select Sign In when you finish entering your details.
If you set up two-factor authentication, you're prompted to enter a verification code. Enter the number and select Verify.
The patch or update installs. You'll see a progress bar as it installs.
When the update is finished, a list of Updates Installed in the Last 30 Days appears. When the installation is complete, close the App Store.
You may not see any updates available if your system is set to Automatically keep my Mac up to date. OS updates also appear in System Preferences > Software Updates.
