How to Extract Files from a ISO Disk Image on macOS

ISO files are sector-by-sector copies of optical discs. They're commonly used for operating system installers, bootable media, and large software distributions. macOS can mount ISO files natively, but extracting individual files requires additional steps.

The default way to open ISO files on macOS

Tool: Finder / hdiutil (built-in)

$ hdiutil attach image.iso

Steps

  1. Double-click the .iso file in Finder to mount it.
  2. The ISO mounts as a read-only volume.
  3. Browse and copy files from the mounted volume.
  4. Eject when done using the sidebar eject icon.
  5. From Terminal: hdiutil attach image.iso
Note: macOS mounts ISO images as read-only volumes. You can copy files out freely. Some ISO files may not mount if they use unusual filesystems.

Extract individual files from a ISO archive

While the default macOS tools support selective extraction, the process typically involves Terminal commands. MacPacker makes this effortless with a visual file browser — just browse the archive contents and drag out what you need.
