I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format.

file says my dmg file is a VAX COFF executable.

First, mount the dmg image : sudo hdiutil attach <image>.dmg

The image will be mounted to /Volumes/<image>. Mine contained a package which i installed with: sudo installer -package /Volumes/<image>/<image>.pkg -target /

Finally unmount the image: sudo hdiutil detach /Volumes/<image>.

I wrote a blog post about installing .dmg files that you can save as a recipe for the apps you use on your machine. Hope this helps: –  grant May 26 at 19:27

You should be able to mount the .dmg using:

hdiutil attach /path/to/file.dmg

And then copy its contents (which appears in /Volumes) where ever you like.

You could try the command open disk://host.tld/image.dmg.

open didn't do anything, just exit, without error message. –  philant Dec 5 '12 at 9:36
Yes it does. I just tested it. It won't display anything until the disk image has been completely mounted, so you will have to wait a minute or so before it appears in /Volumes. (It works if you ssh in and type open path/to/file.dmg. I don't think disk://host.tld/ works though.) –  daviewales Dec 5 '12 at 12:19
Helpful, though maybe not exactly what the OP needed. Thanks. –  Danny Whitt Feb 9 '14 at 12:06
