The procedure is very simple and similar to all OSX versions, Mac OS X Mountain Lion, Lion, Leopard, Snow Leopard, Tiger, lets begin the process.
There are several ways to create Disk Image by using folder , from DVD and From ISO Image.

How to  Create new Disk Image

1.Create from Folder
You need to copy the whole data in a folder like (~/Desktop/Isocontent)
Than Select File -> New -> Disk Image From Folder


When the image dialog box appear select the Folder in which we have already put all of the stuff (e.g. ~/Desktop/ISOCONTENT)

    the hdutil parameters on step 3 are out of order – it should be: hdutil makehybrid -o myiso.iso -iso -joliet myiso.cdr — the format is -o [output file] [options] [input file]
