Kernel anti-cheat systems are currently the bane of Linux/Steam Deck gaming, haven’t actually proven to be effective at stopping cheaters (see Valorant for an example), and lead to various security concerns from giving 3rd parties full access to your machine to being used to install ransomware and malware.
Windows tried to restrict kernel access years ago, but backed down under pressure from various companies. However Crowdstrike’s outages have shown the sever consequences of leaving kernel access open, and we might finally see kernel access to be cut off.
I have no idea either way - floating a question.
Did apple previously allow kernel access and then restrict it again? It seems the specific issue with MS vs McAfee etc is due to originally being allowed access, but microsoft restricted it, affecting their products?
Yes, System extensions on macOS Catalina 10.15 or later allow software https://developer.apple.com/support/kernel-extensions/
