Is there a reason why the MacOS distribution for MCP server is called Darwin_blabla depending on the blabla chipset?

General Newbie Questions

Newbie here, returning back to the Mac after being away for 30 years (literally!), and few decades stuck in Windows. Calling out Darwin is a little like says WinNT, isn’t it? Sorry for the dumb question, but I get I have a feeling I’m, missing a little bit of “Neo4J-speak”? Many thanks

Darwin is still the name of the kernel of MacOS ... 1999 onwards.
