Mac has it’s own disk image format (dmg), however it supports ISO as well. One of the things one might want to do is to burn an iso image to a dvd on Mac. You don’t need to buy a fancy-pants program to do the job, Disk Utility comes to rescue for that.
- Insert a blank dvd
- Start Disk Utility
- Select Superdrive (this is your dvd drive)
- Click on Burn
- Select the iso image to be burned
- Burn & verify
