Video discussing file ownership in Linux
Based on the video, you could change Linux. Could you also adjust Mac OS and think of it as working under Linux GNU? I’ve heard Ubuntu is similar to Mac OS and vice versa—so my question. I haven’t used a Mac before, and I only tried Ubuntu once, so I’m not sure how much different they really are. Still, it seems like you might be able to modify Mac OS if you wanted to, even though I personally dislike Mac.
MacOS is not released under GPL and so you can't modify that. You don't even have the source code for MacOS. You can modify Linux all you like but you are legally obligated to open source any modifications under the GPL (if the thing you're modifying is under the GPL).
MacOS originates from BSD, not Linux. The BSD license permits creating a paid, proprietary version of their operating system.
The information comes directly from the source. MacOS is built on UNIX, which connects it to Linux. There isn’t any other public reference linking it specifically.
UNIX was the pioneer in this field. Current UNIX versions include BSD (open source) and numerous commercial operating systems. Linux differs from Unix; it borrows many concepts but isn't classified as one. The BSD license grants broad freedom—you can develop any OS, even close-source it and sell it.
