How to Downgrade From macOS Sonoma Step by Step

In this tutorial, you’ll learn how to downgrade from macOS Sonoma.
What to do if macOS Sonoma is slow on Mac:

Before you downgrade:
Get CleanMyMac X to run maintenance on your Mac:

#1. Back up your Mac

#2. Restore from a Time Machine backup
Connect the Time Machine drive and boot your Mac in Recovery mode.
When you see the startup options screen on an Apple silicon Mac, choose options, then Continue.
When you see the macOS Utilities menu, choose Restore from Time Machine backup and click Continue.

#3. Reinstall the version of the OS that your Mac had originally (only works for Intel Mac)
Shut down your Mac.
Hold down Shift-Option-Command-R and press the power button.
Release the keys when you see the Apple logo.
Choose reinstall macOS.

#4. Downgrade using a bootable installer

Name your USB stick ‘Ventura installer,’ and the installer you downloaded must be in your Applications folder

Downgrading is really not that difficult, even if you use the Terminal method. The most important thing to remember is to backup your Mac before you upgrade.

After Downgrading using recovery mode, will the data on my mac remain safe? In case I don’t have any backup

Guys, I had a problem with the final stage of the procedure. I performed all the various steps (M1):
1. I downloaded the Ventura installer.
2. I configured it via terminal in the USB stick.
3. I backed up the disk data.
4. I shut down the Mac and booted it into recovery mode.
So far so good, except that when I got to choosing the startup disk, it didn't let me use the disk I created with the Ventura installer. It says: ''It is not possible to downgrade the volume''

HELP ME :(
