Let’s make sure your Mac Operating System (OS) is up-to-date.
From the Apple menu in the corner of your screen, choose System Settings or System Preferences
If you chose System Settings, click General on the left side of the window. Then click Software Update on the right.
If you chose System Preferences, click Software Update in the window.
Software Update then checks for new software.
If Software Update finds new software, click the button to install it. The button might be named Update Now, Upgrade Now, Install Now, or Restart Now, for example. You might then be asked to enter your laptop password.
