Install Windows support software

After installing Windows, the support software installs Boot Camp drivers to support your Mac hardware, including AirPort devices, the built-in camera, the Apple Remote, the trackpad on a portable Mac, and the function keys on an Apple keyboard. The software also installs the Boot Camp Control Panel for Windows and the Apple Boot Camp system tray item.

1. After you configure Windows, if you kept the external USB drive that has the Windows support software inserted, an installer starts automatically. Otherwise, insert the external USB drive, then double-click the setup.exe file located in the BootCamp folder.
2. Follow the onscreen instructions.Important: Do not click the Cancel button in any of the installer dialogs.If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.You don’t need to respond to installer dialogs that appear only briefly during installation, but if a dialog asks you to install device software, click Install.If nothing appears to be happening, there may be a hidden window that you must respond to. Look behind open windows.
3. When the support software finishes installing, click Restart, then click Yes.
4. After your Mac restarts, follow the instructions for any other installers that appear.
5. Check for updated Windows support software. In OS X, choose Apple menu > App Store, then install all available updates.
