Intro: How to DualBoot Mac Versions on a Silicon Chipset Mac. (Any Type of Mac.)

I made 2 versions of macOS running on my Mac. It's great for working on different prongams that are too old to run on macOS Sonoma(macOS 14)

STEP 1: Partion Your Mac

Now go to Disk Uititly and partion your mac HD. Erase it a APFS. (You can Format it during Windows or Linux installitation.)

STEP 2: Install Your OS

Now you must make a bootable installer to install your OS.(I will not list the steps to make the USB. Find out on your own)

After that is done restart your Mac.

M1/M2/M3 chipset, hold the power button once you see the apple logo. It will shutdown. Realse and hold untill it says Loading startup options... then boot into your USB.
