Install Macos 11 Big Sur On Unsupported Macs Version

Today I will show you how to Install macOS 11 Big Sur on an Unsupported Mac.
To be clear this guide shows you how to install Mac OS Big Sur, it is up to you to backup your data first and use Big Sur at your own risk, I am not responsible for any loss of data etc...For me as you can see I installed Big Sur and it worked for me, however due to unforeseen circumstances I can't help with all install steps if it doesn't work out for you. I also can't support or guide you on the use of additional Apps you may install like for example Office (word, powerpoint, excel), Final Cut Pro, Photoshop etc... they may work - they may not. However do help others in the comments if you get Apps to work what other are struggling with.
Please make sure your Mac is Compatible here;
