I kicked Bill Gates out of the house about a decade ago, so I too, am waiting for an OSX GUI. Nothing yet. Don't know if they plan to have one or not. In the meantime, you can run Win under Bootcamp our use Parallels for VMWare. Actually, my MBP Retina runs Win10 faster than most non-Apple laptops of similar hardware. I think it's because Apple writes all the drives for the hardware, vs using a patchwork of 3rd party drives.
