The machine is now waiting for scanning.
3. Retry scanning in the application or MF Toolbox.

The delightfully useful Disk Utility built into OS X can burn disk images to optical media in a few easy steps. Read on for how to go about burning your new disc.

Drag and drop your .dmg or .iso file to the left pane in Disk Utility. Now both the blank disk and the .iso/.dmg should be listed.
Select the .iso/.dmg file you want to burn to disc, and click on the Burn button. A dialog box confirming the destination (your blank CD/DVD) will appear.

Sit back and wait while your new disc gets written!
