How to Downgrade macOS Catalina?

Apple allows you to downgrade macOS 10.15 to an earlier version easily. To Downgrade macOS Catalina to an older version, follow the methods given here:

Method 1-Use Recovery

Utilize this method if you have not bought a new Mac with the latest macOS version. In case you have a system with macOS 10.14 or an older version installed, you can make use of the macOS Recovery tool. You will need a couple of things for the downgrading process:

  • A fast internet connection.
  • A backup before you begin the downgrade because it will erase your startup disk.

Make use of the following instructions for the downgrade:

  • First, shut down your Mac system.
  • Now, power on your system.
  • Immediately, hold the Shift+Option+Command+R keys. Since macOS recovery is loading, the startup might take longer.
  • The macOS Utilities screen will now start loading. Choose the Reinstall macOS option and click the Continue button.
  • Select a startup disk and then click the Install button.
  • Follow the remaining on-screen instructions to complete the installation process.
  • When you are done with the installation process, restore the files that you need from the backup.

Method 3-Use the macOS Installer

  • Downgrade your macOS  Catalina using Installer. This method might be tricky because it is not supported after the release of Mojave.
  • In case you have a Mac device with an older version than Mojave, you can still download the macOS Installer.
  • After downloading the macOS Installer, create a bootable USB drive from the installer file.
  • You can use the USB drive any time you want. An internet connection is not necessary.
