Features supported in Windows 10
Boot Camp 6 includes support for the following features of your Mac in Windows 10.
- USB 3
- USB-C on the MacBook (Retina, 12-inch, Early 2015)
- Thunderbolt
- built-in SD or SDXC card slot
- built-in or USB Apple SuperDrive

You can install Windows 10 on an internal drive in your Mac. Boot Camp Assistant helps you create a partition on your drive that's compatible with Windows. When you install Windows on a Mac that includes a Fusion Drive, the Windows partition is created on the mechanical hard drive part of the Fusion Drive (not the SSD).
After you install Windows, you can install the latest version of iTunes for Windows to listen to your music or play videos. You'll need to authorize Windows to play music or videos you've purchased from the iTunes Store.
If some features aren't working when you start your Mac from Windows 10, try reinstalling Boot Camp support software using Boot Camp Assistant.
