Such a disingenuous headline. The article outlines how pre-2012 Mac can’t support Metal, which breaks a bunch of stuff.
An aside: A few years ago, I used OCLP to install Monterey on my old (Early 2013) MacBook Pro 13”. It was fine, until one day it just stopped booting. It wasn’t hardware: Wiped it, reinstalled Catalina, still worked fine. It’s a fun toy to play with, but I wouldn’t want to be depending on it for anything important.
Just like how everyone has an accent. (Especially the people who think they don’t.)
