To downgrade a Mac system, you typically need to back up your data using Time Machine or another backup solution, as the process will erase your current installation. Next, create a bootable USB drive with the desired macOS version using the macOS installer. Restart your Mac while holding the Option key to access the boot menu, select the USB drive, and follow the on-screen instructions to install the older macOS. After the installation, you can restore your data from the backup if needed.

How do you downgrade from Mac OS X to Mac OS 9?

You cannot without erasing your hard drive and installing Mac OS 9 from scratch. Even then Mac OS 9 may not run on modern Mac hardware because Mac OS 9 needs the ROM chip to boot. Modern Mac OS X hardware uses EFI to boot the system instead of a ROM chip to boot. Mac OS X v10.0 - Mac OS X v10.4 support Mac OS 9 applications and can run them, you just need to install the Mac OS 9 compatibility program which can be found on the Mac OS X Install CD.
