Ask HN: Can Apple sue an OS project replicating macOS's “look and feel”?

As a Linux DE where the project expresses its intention to replicate MacOS verbatim (cleanly) - excluding Apple branding, imagery, fonts, etc.

Would they win the lawsuit?

Given it would be open source, would they sue each member of the project individually?

What if each member is in different countries - would they need to be tried in a US court?

I have heard of "trade dress" being applied to certain items, would it apply to software?

Apple are suing Samsung over the lockscreen of Samsung phones, is there a precedent here?
