If the Boot Camp installer doesn't open after using Boot Camp Assistant

If the Boot Camp installer doesn't open automatically after your Mac starts up in Windows for the first time, follow these steps.

After you use Boot Camp Assistant to install Windows on your Mac, your Mac should start up in Windows and automatically open the Boot Camp installer to a ”Welcome to the Boot Camp installer” window. In certain circumstances, this installer might not open automatically. Follow these steps to open it manually and complete the process of installing Windows support software (drivers).

Open the installer from the BootCamp folder

Because Windows drivers haven't been installed, it might be easier to use a mouse or keyboard that connects via USB instead of Bluetooth, until these steps are complete.

  1. From File Explorer, open the OSXRESERVED partition, which is usually the D drive.

    If you don't have this OSXRESERVED partition, follow the steps to download and install Windows support software instead of the steps in this article.

  2. Open the BootCamp folder, then open Setup. Open Setup only from this folder, not another location.*
  3. When you're asked to allow Boot Camp to make changes to your device, click Yes.
  4. Click Repair to begin installation.
  5. After installation completes, click Finish, then click Yes when you're asked to restart your Mac. 

* If you prefer, you can open Setup by typing D:\BootCamp\setup.exe from the command prompt.
