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 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 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 image.bin and image.cue, you can now convert the bin/cue file to iso using the following command:

bchunk image.bin image.cue outputimage

bchunk will create the disk image outputimage.iso which you can open for it to be mounted on your Mac.
