Synopsis

hdiutil action [options]

hdiutil works with disk images, such as ISO or DMG files downloaded from the Internet. You can mount, unmount, create, resize, verify, and even burn images onto discs. To mount an ISO file mydisk.iso as a volume and access its contents, run:

➜ hdiutil attach mydisk.iso
➜ ls /Volumes
MyDisk             It’s mounted in /Volumes

To unmount it when you’re done, use the detach action, passing it the name of the mounted directory in /Volumes:

➜ hdiutil detach /Volumes/MyDisk

To check that the image is valid and undamaged, run:

➜ hdiutil verify mydisk.iso

To burn the image to a CD or DVD, run:

➜ hdiutil burn mydisk.iso

hdiutil has many other actions and dozens of options: see the manpage for details.
