where’s the business case for Apple?
There is a sizable customer base that runs OSes other than just macOS on their Macs, but appreciate the reliability and/or design of Apple hardware.
From my experience, this base is mostly developers, especially web and server software developers, along with consumers that want to game on the side plus some business folks.
Apple mentioning publicly that it’s up to MS to support Windows on macOS suggests it’s at least a big enough base for them to notice. Not sure beyond that tho.
EDIT: I wouldn’t be surprised if Intel licensing fees comprise at least 5% of the cost of (low-to-mid range) Apple hardware, if not closer to 10%. So now there’s an even greater incentive for Apple to sell hardware to these folks since they get much more profit.
