Downgrading your macOS can seem like a daunting task, but it doesn’t have to be. Maybe you’re not a fan of the latest update, or perhaps the new macOS isn’t compatible with software you need for work. Whatever your reason, here’s a quick guide to help you revert to an older version of macOS.
Step by Step Tutorial on Downgrading macOS
Before we dive into the specifics, let’s briefly discuss what these steps will do. Downgrading your macOS essentially means uninstalling the current operating system and reinstalling an older version. This process can be a bit tricky, so follow these steps carefully.
Step 1: Backup Your Data
Before you do anything, make sure you backup your data.
When you downgrade your macOS, you’ll be erasing everything on your computer. That means all your files, apps, and settings will be gone. Use Time Machine or another backup method to save everything you don’t want to lose.
Step 2: Create a Bootable Installer
You’ll need a bootable installer for the macOS version you want to install.
To create a bootable installer, you’ll need a USB drive with at least 12GB of storage and the installer file for the macOS you want to downgrade to. You can download older macOS installers from the App Store or Apple’s support website.
Step 3: Erase Your Mac’s Startup Disk
Now, you’ll need to erase your Mac’s startup disk using Disk Utility.
Boot your Mac into Recovery Mode by restarting your computer and holding down Command + R. Open Disk Utility, select your startup disk, and erase it. Make sure to choose the correct format recommended for your Mac.
Step 4: Reinstall the Older macOS
With your startup disk erased, you can now install the older macOS.
Plug in your bootable installer, restart your Mac while holding down the Option key, select the installer, and follow the prompts to install the older macOS. This process can take some time, so be patient.
After you’ve completed these steps, your Mac will run the older version of macOS. You can then restore your data from your backup and get back to work (or play).
