How to Downgrade Your macOS Using an Older Installer and Time Machine Backup

Are you tired of your current macOS version and want to go back to an older one? With the help of an older installer and Time Machine backup, you can downgrade your macOS with ease. In this article, we will walk you through the steps on how to do it.

Downloading the Older Installer

Once you have downloaded the specific macOS installer for your Mac, you can use it to create a bootable disk from which you can reinstall an older version of macOS. You can download the installer through the Software Update section of System Settings and find it in your Applications folder afterwards.

Downgrading Using an Older Installer

To downgrade using an older installer, follow these steps:

1. Follow the prompts to complete the reinstallation.

2. Restore your files from the backup you created earlier.

Restoring with Time Machine Backup

If you have a prior Time Machine backup, you can use it to install an older version of macOS. Here's how:

1. Plug in your Time Machine disk and power down or restart your Mac.

2. Press Command+Space, type Disk Utility, and press Enter to open it.

Using a Time Machine backup is another simple way to install an older version of macOS. You'll need to use the Disk Utility built into your Mac to work with partitions. You can also create separate partitions for your Time Machine backups and personal files, which will ensure you always have room for your personal files.

Creating Separate Partitions

To avoid filling up the entire drive, consider creating separate partitions on your external drive for your Time Machine backups and personal files. This way, you'll have a dedicated space for each type of file.

Downgrading your macOS to an older version is possible with the right tools and steps. By following these instructions, you can easily reinstall an older version of macOS using an older installer and a prior Time Machine backup.
