What benefits would I get if I compiled my own XNU kernel for my MacBook Pro (early 2011)? I used to use hacked kernels back in the Tiger day's to run OS X on unsupported machines/CPU's. I know OS X is not Linux but I have compiled Linux kernels in the past for different machines for specific tasks and such (low latency, different CPU scheduler, etc). Just a thought. Not really serious about it at all really, just wanted to know what you guys thought.
