Import kexts from newer versions of macOS

[tjthelion]

Is there any way to bring graphics card kexts from newer versions of macos to old versions? I want to use the 6600 XT in Big Sur but it’s only supported after Monterey 12.1.

No, the reverse is often possible, as is the case with using Nvidia Pather in Monterey for the old Kepler series of graphics cards. Usually the newer drivers/kexts rely on newer frameworks that aren't present in the old OS, so the kexts don't function correctly, if they even load.
