How to Convert BIN Files to ISO Files on a Mac
Once you convert BIN files to ISO files, you have a CD image that works on your Mac. (cd on cd image by Stephen Kirkby from

BIN is a popular file format for CD image data on PCs. Always paired with a CUE file, the BIN/CUE combo contains all the disc data, allowing you to create an exact replica of a CD. Unfortunately, Macintosh computers do not support BIN/CUE. You will need to convert the BIN file to a Mac-friendly ISO disc image. There are a variety of ways to do this using third-party downloads.

Skill level:
Moderately Easy

Things you need

  • Toast, BinChunker or Burn (see Resources section)
  • Blank CD (if using Burn)

  1. 1

    Convert the BIN to ISO using Toast. The program costs £51.90, as of 2010, but is far and away the premiere burning software for Mac users and is an investment that will pay off again and again. Toast offers the quickest and easiest way to convert to ISO. You just open the BIN file with Toast, then select "Save As Disc Image" from the file menu. The program will prompt you with a ".toast" file, but all you do is change the extension to ".iso" and save.

  2. 2

    Convert the BIN to ISO using BinChunker. This software is free, but requires coding that may intimidate some users. It runs using the Terminal tool on your Mac. Open Terminal after installing BitChunker and type two commands: "sudo cp bchunk /usr/bin/" and "bchunk myinputfile.bin myinputfile.cue myoutputfile." In the second command, change the filenames to match your BIN and CUE files.

  3. 3

    Convert the BIN to ISO using the Burn application. This program is free, but requires the intermediary step of burning a CD. After you load it, select "Open" from the file menu and select your BIN and CUE files. Click "Burn" to burn this to a CD. When the CD finishes burning, you can create the ISO file using Disk Utility, a tool included with your operating system. Just click "Convert" from the images menu and select the ISO format.

Tips and warnings

  • BIN files should always be paired with CUE files. Indeed, it is impossible to create a BIN image without an accompanying CUE. On the off chance that someone deleted the CUE file, though, look under "Create a CUE file" in the Resources section to recreate it using TextEdit.
