Show HN: My website, with a MacOS-like interface

No menu bar, no dock. Not MacOS-like interface; I think you meant window decorations. I think it needs a bit more than just macOS-like windows.

Looking at github, the OP is 16. not to reduce you to your young age, OP, but great work. I hope you take the criticism in the right way. When i was 16, my websites did not look at all that good. Well done!

Unusable on mobile and feels incomplete

android mobile i only see a bg image and an icon, not sure what im.. meant to do?

cool site!
