Burning ISO CDs and DVDs
Because I always forget and freak out that I’m gonna create a coaster:
How to burn ISO disc images
1. Insert a blank disc.
2. Start Disk Utility.
3. From the File menu, choose Open Disk Image and select the ISO to be burned.
4. In the list of volumes, you will now see an item representing the ISO file. Select it.
5. Click the Burn button and follow the instructions.

Force eject cdrom or dvd from the command line and other os x disk utilities
