If you’ve recently upgraded your Mac to Catalina, but are experiencing issues or compatibility problems, you might be considering downgrading to Mojave. While the process may seem daunting, fear not! In this step-by-step guide, we will walk you through the process of downgrading from Catalina to Mojave.

Before You Begin:

Before you start the downgrade process, there are a few things you should keep in mind:

  • Make sure to back up all your important files and documents. Downgrading your operating system can result in data loss, so it’s always better to stay on the safe side.
  • Ensure that you have a bootable Mojave installer. If you don’t have one, you can create it using another Mac or obtain it from the App Store.
  • Have a reliable internet connection. The downgrade process involves downloading and installing software, so a stable internet connection is essential.

Step 1: Back Up Your Data

Before doing anything else, take the time to back up all your files, applications, and settings. This will provide a safety net in case anything goes wrong during the downgrade process.

Step 2: Boot into Recovery Mode

To begin the downgrade process, you need to boot your Mac into Recovery Mode. Follow these steps:

  1. Restart your Mac and hold down Command + R as it begins to boot up.
  2. Release the keys once you see the Apple logo or a spinning globe.
  3. Wait for the macOS Utilities window to appear.

Step 3: Erase Your Catalina Drive

Now that you’re in Recovery Mode, you need to erase your Catalina drive before installing Mojave. Here’s how to do it:

  1. Click on Disk Utility in the macOS Utilities window.
  2. Select your startup disk (typically named ‘Macintosh HD’).
  3. Click on Erase, then choose a name for your drive (e.g., ‘Mojave’).
  4. Select APFS or Mac OS Extended (Journaled) as the format.
  5. Click on Erase to format your drive.
  6. Exit Disk Utility once the process is complete.

Step 4: Install Mojave

Now that your Catalina drive is formatted, you can proceed to install Mojave. Follow these steps:

  1. Return to the macOS Utilities window.
  2. Click on Reinstall macOS.
  3. Follow the prompts to select your Mojave drive and begin the installation process.
  4. Wait for the installation to complete.

Step 5: Restore Your Data

After successfully installing Mojave, it’s time to restore your data from the backup you created. Here’s what you need to do:

  1. Once the installation is complete, your Mac will restart.
  2. Follow the on-screen prompts to set up your Mac.
  3. When given the option, select ‘Restore from Time Machine Backup’.
  4. Choose the backup you created before the downgrade process.
  5. Wait for the restore process to finish.

By following this step-by-step guide, you can easily downgrade from Catalina to Mojave, resolving any issues or compatibility problems you may have encountered. Just remember to back up your data, create a bootable Mojave installer, and follow each step carefully. If done correctly, you’ll soon be enjoying the stability and compatibility of macOS Mojave!
