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 /Volumes/<image>/<image>.pkg -target /.

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

So is this how it works on Ask Different? You take someone else's answer and then re-post it as your own, answering your own question? –  trojanfoe Dec 5 '12 at 9:47
@trojanfoe You actually provided a part of the answer while I was researching and answering my own question ; and I up voted your answer. –  philant Dec 5 '12 at 10:10
If you were able to answer the question by yourself they why post the question at all? –  trojanfoe Dec 5 '12 at 10:15
@philant, I believe you have a typo. The installer line (for me) is sudo installer -package /Volumes/<image>/<image>.pkg -target / –  ghayes Mar 5 '14 at 20:09
Perhaps @philant wasn't comfortable editing your post, trojanfoe - so the important idea is getting the answers out while giving proper credit where due. –  bmike Mar 5 '14 at 20:36

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

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.
