Running Linux on a Mac involves installing a Linux operating system alongside or instead of macOS. This can be done through software like VirtualBox or by creating a dual-boot setup. Linux offers a different environment, with its own set of applications and customization options. Users can choose from various Linux distributions to suit their needs, providing access to a wide range of open-source software. It’s a popular choice for developers, researchers, or those looking to explore a new computing experience on their Mac hardware. However, it’s essential to follow proper installation procedures and backup data to avoid data loss.
