Actually it is easy to build Hackintoshes, even with AMD.
Catalina is running stable with Apple ID and all the bells and whistles. In the past when Apple ignored updating Mac Pro Trashcan for several years, we have build a monstrous PC with Hackintosh to run FinalCut.
Search for Open Core Catalina.
I had a hackintosh back in 2009, and recently decided to go at it again and built a custom PC with all the components from https://www.tonymacx86.com/buyersguide/building-a-customac-h....
After a week I never managed to get the OS to install without the installation process crashing towards the end, so it's not "actually" easy even if you know your way around a computer.
Believe me now is so damn easy that it's funny.
Now you have a lot of tools to load kexts and configurations.
In the old days we loaded kexts manually:)
It's not legacy code until the day Apple definitively axes Intel models. The writing is on the wall yes, but they are still selling Intel Macs and they are not deprecated yet. The majority of development still happens on Intel Macs.
I built an 11th-gen Rocket Lake 128GB Hackintosh with Thunderbolt Display support+2 LED Cinema Display recently and it's been great. Thunderbolt 3 support on a Hackintosh has been nice. Just hoping for Thunderbolt 4/Maple Ridge drivers/11th-gen iGPU drivers if ever.
