How to install Windows 10 on Mac
Boot Camp For Mac Free
To install Windows, use Boot Camp Assistant, which is included with your Mac.
1. Use Boot Camp Assistant to create a Windows partition
Open Boot Camp Assistant, which is in the Utilities folder of your Applications folder. Then follow the onscreen instructions.
If you're asked to insert a USB drive, plug your USB flash drive into your Mac. Boot Camp Assistant will use it to create a bootable USB drive for Windows installation.
When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can't change its size later.
2. Format the Windows (BOOTCAMP) partition
When Boot Camp Assistant finishes, your Mac restarts to the Windows installer. If the installer asks where to install Windows, select the BOOTCAMP partition and click Format. In most cases, the installer selects and formats the BOOTCAMP partition automatically.
3. Install Windows
Unplug any external devices that aren't necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.
4. Use the Boot Camp installer in Windows
After Windows installation completes, your Mac starts up in Windows and opens a ”Welcome to the Boot Camp installer” window. Follow the onscreen instructions to install Boot Camp and Windows support software (drivers). You will be asked to restart when done.
If the Boot Camp installer never opens, open the Boot Camp installer manually and use it to complete Boot Camp installation.
If you have an external display connected to a Thunderbolt 3 port on your Mac, the display will be blank (black, gray, or blue) for up to 2 minutes during installation.

Apple has issued an update for Mac OS X Snow Leopard Boot Camp users and a revised firmware for certain iMacs that addresses graphics issues.
Boot Camp 3.1 Drivers
Boot Camp Software Update 3.3 supplies revised Windows support for Macs running Boot Camp 3.x, included as part of Mac OS X 10.6 Snow Leopard. Apple only notes that update supplies 'critical bug fixes and hardware support.'
This update is targeted at users running Windows 7 in either the 32 or 64-bit version via Boot Camp 3.2 on Snow Leopard.
Boot Camp For Mac Os
Macs running 10.7 Lion do not need the update, as that version (Boot Camp 4) can upgrade itself. Users running Boot Camp 3.2 can download the new package through Software Update or from Apple's download page.
Apple released a 'Boot Camp 3.2 update for Windows 64-bit' yesterday, which it states that it added 'support for the ATI-Radeon HD 5870 graphics card, Apple USB Ethernet Adapter, MacBook Air SuperDrive, and addresses critical bug fixes.'

That update addressed users of Windows XP, Vista or Windows 7 running BootCamp 3.1 on Snow Leopard.

Apple doesn't specify which iMac models the firmware update targets, but the package will only install on applicable models and requires Mac OS X Lion. iMacs that need the update can download it through Software Update or from Apple's download page.
