All operating system systems have hardware requirements. Just because you need to upgrade your system in order to get the latest operating system, doesn’t make the operating system any less free.

You are manufacturing connections that aren’t there in assigning meaning whether there isn’t any just cause you refuse to admit the fact that macOS is free. I guess you just hate Apple that much, but I try not to get so emotionally involved

Repeating the same absurd argument over and over doesn’t make it any more true.
