If you’ve ever downloaded a linux distro in the form of an ISO disc image, you may be wondering how to burn it to a DVD in order to make it bootable. So here are the steps for burning an ISO disc image to a DVD. All you need to get started is a blank DVD, and a linux distro ISO image.

1. Insert the blank disc into your mac. When it pops up asking how you want to open it, choose finder.
2. Open Disc Utility(Macintosh HD > Applications > Utilities > Disk Utility), and you should see the dvd on the left hand menu bar.
3. Choose File > Open Disk Image and you should see the mounted disk image on the left hand menu bar below the dvd you inserted.
4. Click on the ISO file(not the mounted drive) and then click burn at the top left corner of the disk utility window.
5. Follow the onscreen instructions and choose the options you want to burn the disc with.
6. Click “Burn”

That’s it, the disc should start burning and eject on it’s own unless otherwise specified. It’s slightly hidden but pretty straight forward once you know where to go.

Cheers
