The hardware has nothing to do with it
its the OS, that is optmized for certain specific conditions that Apple controls
Apple hardware is identical to Windows PC hardware. The only difference is Apple uses their own EUFI implementation to control what is installable. Using a hack of the EUFI you can actually install ANY OS on Apple's computers. There hardware is only proprietary at the "design" level.
Where you're seeing SOME better performance is the Operating system itself and what hardware access it allows the software to have. Apple reserves certain API's and system calls exclusively for their software, and I'll give them credit that they can make great efficient software.
But they can do this because they don't have a wide array of hardware to support. Unlike WIndows, which can handle just about any hardware you can throw at it, OSx does not include drivers and API's for everything under the sun.
However, once you strip out those calls, performance is very similar in most cases. And anything, similar to gaming in style, OSx currently severely lacks, and performs significantly worse than their windows counterparts.
I have tested this on multiple hardware platforms running both OSx and Windows. There are some places Apple excells at no matter what hardware it's on, Their own, or a hackintosh, and some that it fails at, no matter what hardware their on.
and yes, you have a bias (almost everyone does, that itself isn't wrong). I just want to say that if you're going to make comparisons, do so from a position of knowledge, and from equal footing. it's like comparing a $500 windows piece of **** laptop to Apple's $2500 one and wondering why that $500 only lasted 1 year and was a laggy piece of junk.
TLDR version: It has nothing to do with "Optimized hardware" but more to do with Apple optimizing specific items in their software for a limited set of hardware configurations.
