How or what application do I need to open dmg files on my iPhone?

You can only place in your files app and then move it to a Mac via finder where you can unzip the container - DMG is a disc image file used in the main to compress and distribute desktop software including the MacOS operating system .

Nothing can be done with it other store it with iOS and although the download function in mobile Safari now works for documents , images and music to the files app , you can’t use it to install and circumvent the App Store secure walled garden for software .

Hi UnderstandingDevelopment,

I'm not sure I understand the question, so let's see if we can clarify:

• Did you download the dmg file onto your iPhone and are wondering how to open it?

• What type of file/app did you download that was delivered in dmg format?

dmg files usually contain applications/physical disk information specific to MacOS, so the contents are generally not going to be readable by or compatible with iOS.
