Why each option
The .dmg file extension indicates a disk image file format natively used and supported by macOS for software distribution.
iOS uses different application package formats (like .ipa for apps from the App Store) and does not natively support .dmg files.
Windows operating systems do not natively support .dmg files and require third-party software to open or extract their contents.
A .dmg (Apple Disk Image) file is a proprietary disk image format used primarily on macOS for distributing software. These files can be mounted as virtual disks and their contents installed on Mac OS systems by default.
Chrome OS is based on Linux and uses different package formats (e.g., .deb for Linux apps, web apps) and does not natively support .dmg files.
