Once in a while you might come across CD images in the format of a .bin file and .cue file. These are format popularized by CDRWin which is a Windows program. In order to use the CD image in Mac, you have to convert the bin/cue format into the disk format supported by Mac OS X using third party application.
[Roxio Toast](http://www.roxio.com/enu/products/toast/default.html) CD burning software is able to convert bin/cue format into Mac OS X disk format. But this will set you back at least $80. Or you can use the free and open source command line tool bchunk to convert the bin/cue files into iso image that can be mounted on Mac OX X.
It is recommended to obtain bchunk from MacPorts:
* [Download and install MacPort](http://www.macports.org/install.php) if you have not done so. MacPorts is a community driven effort to make it easy to obtain and update open source software on the Mac OS X.
* Open the Terminal app and install bchunk port using the following command line:
sudo port install bchunk
* Let say your bin/cue files are
bchunk image.bin image.cue outputimage
bchunk will create the disk image
