I volunteered with a non-profit several years ago, and due to the competition for the available Windows machine, I located an old iMac nobody was using - large flatscreen era, but still apparently too old for system updates. And apparently could not properly connect to secure websites.

It made me sad, particularly because an organization like that can't really afford Apple prices and yet they also can't afford an IT department which is probably why someone bought it originally figuring it would "just work".

I realize in principle I could've installed Linux on it, but didn't see any point.
