Sometimes, for various reasons, it may be necessary to revert to a previous macOS version. Don’t worry; it is possible to do so! In this article, we will guide you through the process step by step and answer some common questions along the way.

Why would I want to downgrade my Mac OS?

There could be several reasons. Some software or applications may not be compatible with the latest macOS version, or you might experience performance issues. Additionally, if you upgraded your Mac and found that certain features or changes are not to your liking, downgrading can be a solution.

Can I downgrade my Mac without losing data?

Unfortunately, downgrading macOS involves erasing your computer’s hard drive, meaning you will lose your data unless you have a backup. Therefore, it is crucial to back up your important files and documents before proceeding with the downgrade process.

How do I create a backup?

The simplest and most reliable method to back up your Mac is by using Time Machine, which is built into macOS. Connect an external hard drive, open System Preferences, click on Time Machine, select the disk you want to use for backups, and click the “On” switch. This will create regular backups of your data, ensuring you can restore them after the downgrade process is complete.

What are the steps to downgrade macOS?

To downgrade macOS, you will need to perform a clean installation of the desired previous version. Here are the steps:

1. Back up your data using Time Machine or any other preferred method.
2. Create a bootable installer for the earlier version of macOS using a USB drive. You can find detailed instructions on Apple’s support website.
3. Restart your Mac with the USB drive connected and hold down the Option key.
4. Select the bootable installer on the startup disk selection screen and follow the on-screen instructions to install the earlier macOS version.
5. After the installation is complete, you can restore your files and apps from the backup you created earlier using Time Machine.

Can I downgrade from the latest macOS version to any previous version?

Apple only allows downgrading to the previous macOS version that was available at the time of your Mac’s purchase. For example, if your Mac shipped with macOS Catalina, you can only downgrade to macOS Catalina or earlier.

How do I prevent automatic updates in the future?

If you wish to avoid automatic updates to future macOS versions, you can disable them. Open System Preferences, click on Software Update, and then click on Advanced. Here you can deselect the box that says “Check for updates” to prevent your Mac from automatically downloading and installing any new macOS updates.

Remember, downgrading your Mac OS to an earlier version is a complicated process that should only be done if necessary. Make sure to follow the instructions carefully and back up your data to avoid any potential loss. If you’re unsure or uncomfortable performing the downgrade yourself, it’s always a good idea to consult with a professional.
