I don't think anything to do with Intel matters, as the existing Mac solution they provide is just running Java Edition which already runs natively on ARM anyway.

Honestly I'm confused why they haven't brought Bedrock to Mac yet, as MS makes Mac versions of tons of stuff, from Edge to Copilot to Office; and Minecraft Bedrock Edition not only sells for money but has recurring in-app-purchase revenue, and Macs seem to be selling well.

Why does dropping Intel support relate to this?

Most iPad apps can already be ran on OSX.
