Make sure the ISO or CDR file is selected.

Click the 'Burn' button at the top of the window.

Drag the newly-created CDR file into the left frame of Disc Utility and proceed.

This will create a CDR file on your desktop.

Click Save and wait for the conversion to complete.

Select 'DVD/CD master' from the 'Image Format' menu.

Select 'Desktop' from the 'Where' menu.

Make sure the ISO file is selected and click the 'Convert' button at the top of the window.

This isn't required if you're burning a Mac-format ISO. If you need to use the burned disc to boot a PC, such as a Windows or Linux installation disc or a utility disc like DBAN, you may need to convert the ISO file first.

Convert the ISO file if you want it to be bootable on a PC.

In Yosemite (OS X 10.10), the ISO file will need to be on your desktop first before you can drag it into Disk Utility.

Click it to select it once you've added it to the list. You'll have to release it underneath your list of drives.

Drag and drop the ISO file into the left frame of the Disc Utility window.

Open 'Applications' → 'Utilities' → 'Disk Utility'.

All Macs include the Disk Utility program, which can perform a large number of disk-related tasks.

The disc types supported by your Mac will be listed in the right frame. Select the 'Disk Burning' option in the left frame. To see what your Mac supports, click 'Apple' → 'About This Mac' → Template:MacButton. The size of the ISO file will determine the type of disc you need to use: ISO files are image files of DVDs or CDs that are burned to blank discs to replicate the original disc.
