Why downgrade from macOS Sequoia to Sonoma?

There are several reasons why Mac users may choose to downgrade MacOS Sequoia to MacOS Sonoma.

One of the most common issues is slow performance, or frequent system freezes, especially if your Mac is older or has limited resources.

Some users may also experience app compatibility issues, as specific programs have yet to be fully optimized for macOS Sequoia.

In other cases, macOS Sequoia bugs or glitches may lead to system crashes, making it difficult to work efficiently.

Additionally, some users simply prefer the stability and familiarity of a previous macOS, as newer versions of the operating system can sometimes introduce unexpected changes or remove features that you rely on.

Before you downgrade macOS Sequoia

Before you begin the downgrade process from macOS Sequoia to Sonoma, it’s crucial to take a few preparatory steps to ensure the transition goes smoothly and without data loss.

1. Prepare a Time Machine backup

Creating a backup before downgrading is essential to ensure you don’t lose any important files or data.

Before you begin, you’ll need an external storage device. Ideally, the device should be twice the size of your Mac’s hard drive to store all your files safely.

Here’s how to prepare your backup:

  1. Connect the external backup drive to your Mac.
  2. Open Disk Utility from Applications > Utilities.
  3. Select your backup drive and click Erase.
  4. In the Format drop-down menu, choose APFS (for macOS High Sierra and later) or Mac OS Extended (Journaled) (for earlier macOS versions), then click Erase.
  5. Once the drive is formatted, close Disk Utility.

Now, you’re ready to set up your Time Machine:

  1. Connect an external backup drive to your Mac.
  2. Go to System Settings > Time Machine.
  3. Select Add Backup Disk and choose the desired disk.
  4. Click on Set Up Disk and configure which files to back up and how often.

With your backup ready, you can start downgrading macOS Sequoia, knowing that your files are securely stored and recoverable if needed.

2. Clean your Mac from junk files

Before downgrading, it’s a good idea to clear out any junk files and unnecessary data that may be cluttering your startup disk.

This ensures a smoother downgrade process and better performance once macOS Sonoma is installed.

The easiest way to do this is to use SpyHunter for Mac, which can help identify and remove junk files, old logs, and other unnecessary data with just a few clicks

This not only frees up valuable disk space but also helps prevent potential issues during the downgrade.

  1. Download SpyHunter from here and install it.
  2. Run a Quick Scan and review the detected junk files.
  3. Select the files you want to remove and follow SpyHunter’s prompts to free up space on your Mac.

How to downgrade macOS Sequoia to Sonoma

If you’ve decided to downgrade macOS Sequoia to Sonoma, there are several reliable methods to make the transition without losing your data.

Below, we’ll outline three practical ways to revert to macOS Sonoma: using a Time Machine backup, macOS Recovery Mode, or a bootable macOS installer.

1. Downgrade using Time Machine

If you made a Time Machine backup before upgrading to Sequoia, downgrading to macOS Sonoma is straightforward. By restoring from a previous backup, you can revert to the earlier macOS version while keeping your files intact.

Here’s how to downgrade macOS Sequoia using your backup:

  1. Connect the drive with your Time Machine backup to your Mac.
  2. Restart your Mac in Recovery Mode:
    • For an Intel Mac: Press and hold Command + R as you power on your Mac until the Apple logo appears.
    • For an Apple Silicon Mac: Hold down the power button until you see the Startup Options screen. Select Options and click Continue.
  3. Once you enter the macOS Recovery environment, select Restore from Time Machine.
  4. Choose the Time Machine backup drive as the restore source.
  5. Select the backup from which you want to restore. Ideally, choose a recent backup made before upgrading to macOS Sequoia (labeled as being created with Sonoma).
  6. Click Restore and follow the on-screen instructions.

After completing these steps, your Mac will reboot with macOS Sonoma installed, bringing your system back to its previous state while keeping your important files intact.

2. Downgrade in macOS Recovery Mode (Internet Recovery)

If you don’t have a recent backup, you can still downgrade macOS Sequoia to macOS Sonoma using macOS Recovery Mode.

This method, known as Internet Recovery, allows you to reinstall the version of macOS that initially came with your Mac or the closest compatible version, which might be macOS Sonoma.

Follow these steps based on your Mac type:

For Intel Macs:

  1. Shut down your Mac completely.
  2. Press and hold Shift + Option + Command + R, then press the power button. This key combination ensures your Mac reinstalls the version of macOS that originally came with your Mac.
  3. Release the keys when you see the Apple logo.
  4. When the Mac Utilities window appears, choose Reinstall macOS.
  5. Follow the on-screen instructions to reinstall the previous version of macOS.

For Apple Silicon Macs:

  1. Shut down your Mac completely.
  2. Press and hold the power button until you see the startup options screen.
  3. Click Options, then select Continue to enter macOS Recovery.
  4. Then, click Reinstall macOS from the Utilities window and follow the on-screen instructions.

Once the installation is complete, your Mac will restart with the downgraded macOS version. From here, you can upgrade to macOS Sonoma if needed.

3. Downgrade using a bootable installer

If you prefer a clean install, downgrading macOS Sequoia using a bootable installer is a reliable method. To download the macOS Sonoma installer, you’ll need a USB drive (preferably 32GB) and access to another Mac.

Follow these steps to create the installer and use it to downgrade.

  1. Insert a USB stick (32GB recommended) into your Mac.
  2. Open Disk Utility from Applications > Utilities, select the USB drive, and click Erase. Choose Mac OS Extended (Journaled) as the format and name the drive macOS Sonoma Installer.

  1. Download macOS Sonoma from the Mac App Store. Once the download completes, the installer will open automatically—press Command + Q to quit. The installer will now be saved in your Applications folder.

  1. Open Terminal and enter the following command: sudo /Applications/Install\ macOS\ Sonoma.app/Contents/Resources/createinstallmedia --volume /Volumes/macOS\ Sonoma\ Installer
  2. Press Return, enter your admin password, and wait for the bootable USB installer to be created. This process may take some time.

  1. When the installer is ready, restart your Mac.
  2. Hold the power button (on Apple Silicon Macs) or the Option key (on Intel-based Macs) until the startup options screen appears.
  3. Select the USB installer as the startup disk, then click Continue.
  4. Once the macOS Utilities window appears, select Disk Utility and choose your startup disk (usually labeled Macintosh HD).
  5. Click Erase, format it as APFS, and confirm.
  6. After erasing your startup disk, exit Disk Utility and choose Install macOS Sonoma from the macOS Utilities window.
  7. Follow the on-screen instructions to install macOS Sonoma. The installation process will take about 30 minutes, during which your Mac may restart several times.

By following these steps, you’ll successfully downgrade from macOS Sequoia to macOS Sonoma using a bootable installer. Remember to back up your data beforehand to avoid any potential data loss.

Now that you know how to uninstall macOS Sequoia and revert to macOS Sonoma, you can restore your Mac to a version that works better for your needs.

Whether you experienced performance issues, app incompatibility, or simply prefer the previous version, the methods outlined above will help you safely downgrade without losing your data.

Just remember to backup files before starting the process to ensure a smooth transition. Downgrading doesn’t have to be complicated, and with the proper steps, you’ll be back to your preferred macOS version in no time.
