Apple Updates Boot Camp Support For Windows 10, Here's How
Apple's latest Boot Camp build supports 64-bit flavors of Windows 10 on several Macs, including MacBook Air models from mid 2012, MacBoo Pros from mid 2012, MacBook Pro with Retina display models from mid 2012, iMacs from late 2012, Mac mini systems from late 2012, Mac Pros from late 2012, and the new 12-inch Retina MacBook.
You may recall that the new 12-inch Retina MacBook sports just a single port -- USB Type-C (which is a USB 3.1 Gen 1 port, meaning it tops out at 5Gbps, not 10Gbps like USB 3.1 Gen 2). On these systems, Boot Camp 6 brings support for the USB Type-C port in Windows 10. And for all compatible Macs, you'll find support for USB 3, Thunderbolt, built-in SD and SDXC card slots, built-in USB Apple SuperDrives, and Apple's keyboard, trackpad, and mouse.
The necessary support software (drivers) for Windows 10 are automatically downloaded when you use Boot Camp Assistant. To perform a new install of Windows 10 on your compatible Mac, check for updates to make sure you're running up to date versions of OS X, your Mac firmware, and Boot Camp Assistant. You'll also need an ISO file of Windows 10 64-bit (you can download it here) along with a USB flash drive.
Once everything's in order, open Boot Camp Assistant from the Utilities folder and follow the instructions to install Windows.
