Have you been wondering how to convert .DMG files made on MAC platform into .ISO or .IMG files so that it can be used easily in windows or Linux platform.
Well, I’ve come accross these miniscule tools which does the job perfectly as well as its free. They are made by vu1tur.
dmg2img: Converts .DMG file to .IMG file.
dmg2iso: Converts .DMG file to .ISO file.
I’ve also noticed that MagicISO does handle .DMG files. I can open it, so I guess it can also generate an .ISO file on behalf of it. If you’ve got MagicISO as well as it worked on behalf of you, please let us know by adding a comment below. Thanks  
Don’t forget once you’ve made your .ISO or .IMG file, save the world by avoiding burning unnecessary CD/DVD on behalf of single utilize only. Use a CD/DVD emulator like daemon tools which shall save you time as well as money. Or if you got some money to spare as well as desire a more powerful CD/DVD emulator, endeavour Alcohol 120%.
