If you are on a macOS that is prior to Catalina (version 10.15), EIT is now asking you to upgrade to macOS Catalina. If you are unsure what version you are currently on, click on the Apple icon (upper-left corner) and then select About this Mac. If the version number is below 10.15, then you will need to upgrade to macOS Catalina using the directions below.

Note: this is a two-step process. For the first step, you are downloading the installer. It’s a big file (about 8.5GB) and could potentially take up to 2 hours to download, depending on your network speed. With the second step, you are installing Catalina from the installer, which could potentially take another hour. The typical time frame to complete the upgrade will be shorter but be aware that it could take a few hours, so plan accordingly.

  1. First, you will need to quit all open applications, click the Apple icon (upper-left corner), and select Restart. After logging back in, open the Self Service application (found in your Applications folder or by using Spotlight Search).
    Self Service applicationSelect the Install button below macOS Catalina. This doesn’t actually perform the upgrade, it just downloads the Install macOS Catalina application into your Applications folder. You can continue using your Mac during this step.
    Install OS buttonDownloading OS installer
  2. Once you see Installed (or Reinstall in some cases) below macOS Catalina in Self Service, go to your Applications folder (in Finder) and find Install macOS Catalina. Click and follow the prompts to install the software. You will be unable to use your Mac during this step.
