Which utility allows a Mac user to dual-boot macOS and Windows?

The correct answer is Boot Camp because it is the official utility developed by Apple that allows Mac users to install and run Windows alongside macOS on their devices. Boot Camp assists in partitioning the hard drive, enabling users to allocate necessary space for Windows while maintaining their macOS environment. It ensures compatibility with Windows drivers and allows the user to choose which operating system to boot into during startup.

Using Boot Camp, Mac users can experience the full functionality of Windows applications and games that may not be available on macOS. This is especially useful for those who need to run specific Windows-compatible software for work or other purposes while still having access to macOS for their other needs.

The other choices listed do not serve this purpose. For example, Ubuntu is a Linux-based operating system and isn't related to dual-booting macOS with Windows. Apt-get is a package management command-line tool used for installing software in Debian-based Linux distributions and does not provide any functionality for dual-booting operating systems on a Mac. Bootrec is a Windows utility used for troubleshooting and repairing the boot process, and it is not designed for use on macOS devices.
