VirtualBox is a free, open-source virtualization platform that allows users to run multiple operating systems on a single computer. Instead of installing another operating system directly onto the Mac, VirtualBox creates virtual machines (VMs) that operate in separate environments within macOS.
It is useful for software development, testing, education, running Linux distributions, and experimenting with different operating systems without changing the main system. Users can configure virtual hardware, install guest operating systems, and switch between virtual machines as needed.
