How to install .dmg file

Hello,
I want to install a software called OmniGraffle Pro, but that file extension is in .dmg so how can I install it on my Windows XP pro with Service Pack 3. Thank you for any replies.

There's a command line tool able to convert a DMG file to an ISO one.
You can download DMG2ISO from here:

Once you have the ISO, you can either burn it with almost any CD burning application, or mount that image as a (virtual) drive with something like Daemon Tools, Vitual CD, etc., or directly see or extract files with other image utilities like CDMage.

I have not tried this, but you could use hdiutil to mount the image and installer to install the packages inside.

.dmg files are mac disk images, they will not work properly.

if you want to enable divx web player in firefox, you need to symlink your /usr/lib/mozilla/mplayerplug-in-dvx.so and /usr/lib/mozilla/mplayerplug-in-dvx.xpt to /usr/lib/firefox/mplayerplug-in-dvx.so and /usr/lib/firefox/mplayerplug-in-dvx.xpt respectively.

A .dmg is a Mac disk image file. You can open dmg files in Windows with tools like TransMacBut beware, only some data files (images, text, movies, sound, etc) would be usable in Windows. You will not be able to install or run Mac applications.
