That’s because “proper” macOS apps close windows not apps when you click the little red dot in the upper left. See some of the answers here https://unix.stackexchange.com/questions/4618/why-mac-applic...

And I agree it’s different from all the other operating systems, once I understood why it made sense.

For example, I can copy an image to my clipboard, and open Preview. No window opens, but the top menu bar shows that Preview is open. From there I can choose the “new from clipboard” entry. It’s just a different model of interaction.

It makes sense if the initial startup of an app is expensive, memory is cheap, and creating new windows is fast.
