It is an exact copy of a hard disk or compact disk. A.DMG file is the disc image file used by MAC OSX. For some reason, if you want macOS in.DMG or.ISO format, there is a method to convert the.app file. Hence it is not mountable nor compatible with operating systems like Windows. Unlike the macOS DMG installer, which Apple doesn’t provide nowadays, the app version of the macOS install package is not bootable.If you have an app that is not available in the.pkg file type, you will need to repackage the.dmg file as a signed.pkg file before distributing with Jamf Now. Jamf Now only supports.pkg files for package deployment.
