Boot Camp Assistant is a multi boot utility included with Apple Inc.'s macOS (previously Mac OS X / OS X) that assists users in installing Microsoft Windows operating systems on Intel-based Macintosh computers.

The utility also installs a Windows Control Panel applet for selecting the default boot operating system.

Boot Camp combines Windows 10 with install scripts to load hardware drivers for the targeted Mac computer.

Holding down the option key (⌥) at startup brings up the boot manager, which allows the user to choose which operating system to start the device in.

On older Macs, its functionality relies on BIOS emulation through EFI and a partition table information synchronization mechanism between GPT and MBR combined.
