Running Windows on a Mac entails using virtualization software like Parallels Desktop or Boot Camp, enabling you to seamlessly run Windows alongside macOS. This facilitates access to Windows-exclusive applications and services, all within the Mac environment. You can switch between the two operating systems as needed, providing flexibility for work, gaming, or software compatibility. This allows Mac users to enjoy the best of both worlds without the need for a separate Windows machine, making it a convenient and practical solution for various computing needs.
