What are DMG and ISO Files?

DMG is a disk image format used on macOS for software distribution, acting as a virtual disk. It often includes compressed and encrypted installation files. Once mounted, users can install applications by copying them to the Applications folder or running an installer. However, DMG files are exclusive to macOS.

ISO files, on the other hand, are compatible with both Windows and macOS. They are commonly used for storing and mounting disk images, such as software installers and bootable systems. Unlike DMG, ISO lacks built-in encryption and compression but offers greater cross-platform usability. Windows natively supports ISO files, making them the preferred format for disk images on non-Mac systems.
