Great, beautiful software with really nice "burning documents" animation (which can also be switched off). You can dispell the smoke by blowing! "You can even blow into your microphone and the smoke will react accordingly. "
Best thing is that disco can span disks. So if you have lots of stuff to burn that will not fit on a single disk, disco will do all the calculations for you to properly fill the disks to the brim. "If Disco detects the total size of the files you're burning is bigger than the disc, it will try to divide them amongst multiple discs so that they fit. "
It can also keep a record of the contents of your burned disks. Wow. "You can instantly search through tens of thousands of burned files and find out info such as when it was burned, to what disc it was burned, and when it was last edited. "
I'm glad this still works as of Aug 2015 on ML 10.8.5. It's such a timesaver and it never ruined a disk.
However, it can crash. If it won't start at all, delete it with App Cleaner, then reinstall. If it still won't start, run a different burning app, then run disco. That helped me. It's fine now.
Wish the developer would release this so disco won't die! It's too good to die. Please...
But thanks for making it free.
