Ask HN: What OS are you running on your Macbook and why?

Mostly OSX. Seriously thinking about ditching the thing and going and getting a Dell XPS 13 Developer Edition, though.

Care to elaborate why you're switching?

Windows 10 under bootcamp as I do a lot of development for Windows. Strangely Win 10 runs faster on my mac than OSX El Capitan.

windows 10, runs faster than macOS and now it is better for development than macOS itself and I could do a load of things much better and faster in w10 so I don't really see the point in using macOS.

How's the battery life?

Its not bad ,gives about the same as macOS. 7-8 hours usually but there was a time when I used to get 12 hours but that was when I just installed w10.

OS X because I don't get paid to futz with my OS to get it working right.

But, most of the time I also have a Linux VM image running to give me a closer production like environment.
