Earlier quoted context omitted.
OSX is 15% market share? Why would they make an entirely separate version on a new line of products just to cater to that, considering the fix you mentioned works for, well anyone not using VMs. (Typed this on a Ducky remapped for OSX)
It's certainly not 15% marketshare among premium corporate users. I bet if you condition on the company spending at least $700/unit on laptops for their employees, Apple's marketshare is more like 70%.
Did you miss a digit there? Seems like a very low bar. Every non-tech company I am aware of spends well more than that on laptops for very basic computer uses.
Where I work, Apple is a choice, but very few people have them. The only people I know who go for them are designers.
