Geek Posted March 16, 2012 Posted March 16, 2012 <div class="KonaBody"><p><img src="http://osxdaily.com/wp-content/uploads/2012/03/iso.jpg" alt="ISO" title="iso" width="125" height="151" class="alignright size-full wp-image-28494" /> You can create ISO images from any source disk or data by using the command line in Mac OS X. This isn’t too different than <a href="http://osxdaily.com/2012/03/13/burn-an-iso-image-from-the-command-line/">burning them</a> through Terminal, and you can use either the hdiutil tool or dd command. </p> <p>While the command line is generally reserved for advanced users, using it to create ISO’s isn’t too complicated and will save you the hassle of having to download any third party apps. If you’re new to the Terminal, remember that dragging & dropping files into the Terminal window will <a href="http://osxdaily.com/2011/03/02/drag-drop-finder-items-into-the-terminal-for-their-full-path/">print their full path</a>, making it easy to point to source files and preventing any navigation through the command line. </p> <h2 style="font-size:1.2em;">Creating an ISO with hdiutil</h2> <p>The most reliable method is uses hdiutil, here is the syntax:</p> <p><code>hdiutil makehybrid -iso -joliet -o image.iso /path/to/source </code></p> <p>Here’s an example, creating an iso from a Windows 7 installer disc, with the end result showing up on the desktop:</p> <p><code style="font-size:95%;">hdiutil makehybrid -iso -joliet -o ~/Desktop/Windows7.iso /Volumes/Windows 7 Install </code></p> <p>The -joliet flag is necessary to make the iso fully compatible with Windows and other OS’s, though if your only requirement is to use the iso on a Mac you can leave it off.</p> <h2 style="font-size:1.2em;">Making an ISO with dd</h2> <p>Another approach is by switching around a previously discussed <a href="http://osxdaily.com/2012/03/13/burn-an-iso-image-from-the-command-line/">dd command</a>, which makes it go from burning an image to creating an image. This may not be as reliable and it requires additional steps, so use dd only if you have a good reason not to use the primary hdiutil method.</p> <p>Use the ‘diskutil list’ command to discover the disks identifier that you will need to make an ISO with dd from.</p> <p><code>dd if=/dev/dvd of=/destination/path/dvd.iso</code></p> <p>dd is often faster than hdiutil, but it’s definitely for more advanced users.</p> <p><strong>Converting Other Disk Image Formats to ISO</strong> You can also convert other disk images like cdr, dmg, and nero images to ISO, <a href="http://osxdaily.com/2009/09/09/convert-a-dmg-to-iso-and-convert-iso-to-dmg-on-mac/">read more about that here</a> if interested.</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/zu5cZ69gb5VJrcj6gr7kANQNsQw/0/da"><img src="http://feedads.g.doubleclick.net/~a/zu5cZ69gb5VJrcj6gr7kANQNsQw/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/zu5cZ69gb5VJrcj6gr7kANQNsQw/1/da"><img src="http://feedads.g.doubleclick.net/~a/zu5cZ69gb5VJrcj6gr7kANQNsQw/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0FgKwsQfKK4:dBJAz0Cis9M:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0FgKwsQfKK4:dBJAz0Cis9M:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=0FgKwsQfKK4:dBJAz0Cis9M:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0FgKwsQfKK4:dBJAz0Cis9M:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=0FgKwsQfKK4:dBJAz0Cis9M:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0FgKwsQfKK4:dBJAz0Cis9M:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=0FgKwsQfKK4:dBJAz0Cis9M:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/0FgKwsQfKK4" height="1" width="1"/> View the full article
