Convert a BIN+CUE CD image to ISO in macOS


Download and extract poweriso to the user binary directory.

curl -o temp-download-delete && tar -xvzf temp-download-delete -C /usr/local/bin/ && rm temp-download-delete

Convert the BIN+CUE to a single ISO file – run this command from the directory in which the BIN+CUE files are stored:

poweriso convert ./"Image Name with Spaces.cue" -o ./"Image Name with Spaces.iso" -ot iso

But why did I want to do this?

Out of nostalgia reasons, I wanted to run Warcraft 2 on my Macbook Pro.

As of December 2018 the game is currently available from although the “ISO” download results in a CUE + BIN file pair instead of a single ISO file.

Since .iso files are generally better supported by modern operating systems and DOSbox tools – such as the embarrassingly easy-to-use – I went hunting to find out how to do the conversion.

After a couple of failed attempts, I found that PowerISO provide a free command line tool for macOS and Linux. After a little more reading and some trial and error, I ended up with the above convert command to successfully convert the BIN+CUE files to a single .ISO.

I could then successfully use the resulting Warcraft 2.iso file to install the game in boxer.

When I were a lad…

I remember Warcraft 2 being a “high resolution” game back when I played it originally – it was SVGA! It’s not high resolution anymore.


Error: Warcraft 2.cue: The file format is invalid or unsupported.

This happens if you do not include the leading “current directory dot slash” ./ at the beginning of the input and output files strings.

Software used
