I stumbled upon this blog entry, where someone describes how to convert bin+cue to iso. I had the same problem as him:
While setting up a new VMWare image I found myself needing to convert an old .bin/.cue disk backup to iso format. Looking for a simple command line utility I came across BinChunker, a GPL-licensed *nix source that fit the bill to the tee. The official site has the source code and RedHat RPMâ€™s but nothing for OS X.
A quick compile took care of that â€” BinChunker for OS X.
Download the utility, extract it to your Home directory and issue the following command from a shell prompt:
sudo cp bchunk /usr/bin/
To make sure your newly installed utility has the correct execute permissions and that its accessible to you through the terminal, run this code:
sudo chmod a+x /usr/bin/bchunk
To convert a .bin/.cue pair to a .iso, you can issue this command:
bchunk myinputfile.bin myinputfile.cue myoutputfile
If you are getting a not found error, make sure that /usr/bin/ is in your path. To check this, type echo $PATH and look for /usr/bin/ in the result. If it isnâ€™t there, type sudo nano /etc/profile and add /usr/bin; to the PATH=â€¦ line. Then press CTRL+x followed by Y to confirm and the enter key to verify the filename to save and exit nano. Then execute source /etc/profile to refresh the path.
