What does Boot Camp allow you to do on an Intel-based Mac?

Boot Camp is a utility provided by Apple that allows users of Intel-based Macs to install and run Microsoft Windows alongside macOS. The primary functionality of Boot Camp is to partition the Mac's hard drive to create separate space for Windows, enabling the user to boot into either macOS or Windows at startup.

The capability to install and run versions of Microsoft Windows, such as Windows 7, is a significant feature of Boot Camp, as it allows users to take advantage of applications and software that are only available on the Windows operating system. This can be particularly beneficial for users who rely on specific professional software, games, or legacy applications that do not have a macOS version.

The other options do not accurately reflect what Boot Camp allows you to do. For example, running iOS applications would not be possible on an Intel-based Mac through Boot Camp, as iOS apps are specifically designed for Apple's mobile devices. Upgrading the Mac operating system is managed through macOS software tools, rather than Boot Camp, and while you can access Linux-based applications, Boot Camp itself is not designed to facilitate that function directly. Thus, the key advantage of Boot Camp is its ability to seamlessly let users run Microsoft Windows on their Intel-based Macs.
