What Is a macOS Catalina DMG/ISO File
macOS Catalina introduces a new method of updating the operating system, using macOS Catalina Installer files which come in two formats: ISO and DMG.
macOS Catalina ISO files Virtual machines are designed to run multiple operating systems on a single physical computer, allowing you to run macOS on a non-macOS device. This is made possible through software like VMware Fusion and Parallels Desktop, which create a virtual environment that can run macOS without affecting the host machine's operating system. This means you can have a virtual machine with a macOS installation, while the physical machine remains running its original operating system, such as Windows or Linux.
