Apple’s MacOS Update
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.
If you chose System Settings, click General on the left side of the window. Then click Software Update on the right.
Software Update will then check for new available 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. You will then be asked to enter your laptop password.
If you have issues updating your Mac to the current version, please email mission-control@squareup.com
