How to Update MacOS

This is a quick guide demonstrating how to update your mac to a new version of macOS.

Notes Before Updating:

  • Always make sure you have a valid backup before attempting an OS upgrade. While things rarely go wrong during OS updates, we want to make sure your data is safe before attempting to upgrade.
  • Before you update to Catalina, you’ll want to check the following:
    • You will want to check to see if you have any 32-bit apps you can’t live without after this upgrade.
      To do this:

      1. Click the Apple icon in the top left corner of your screen.
      2. Select ‘About This Mac.’
      3. Click ‘System Report.’
      4. Scroll down to the ‘Software’ section and click ‘Applications.’
      5. On the right, you’ll see a list of apps and a column labeled 64-Bit (Intel). If any of those apps have a ‘No’ in that column, it means they’re not 64-bit apps, so you’ll need to update them or find a replacement before you update your OS.
  • We are currently advising our users to hold off on updating to macOS Big Sur at this time.

Updating macOS:

  2. Scroll down to the ‘Download MacOS’ heading.
  3. Click the link for the appropriate version of macOS for your computer.
  4. Click ‘Get’ in the app store link to start the download.
  5. When prompted, click ‘Download’ to start the download.
  6. The OS update will take a while to download, as it is a large file. Let it finish downloading. Once downloaded, the installer should automatically start.
  7. After the installer starts, click ‘Continue’ / ‘Accept’ / etc., and then put in your administrator password. Once you put in the password, the installation will start.
  8. After a few preinstallation tasks, your computer will restart, and the OS will finish installing. Once done, you should come back up to a login screen. Log in, and you should be running a newer version of macOS.
