Burning Snow Leopard 10.6 DMG always fails

Posted on


I’m trying to burn my Snow Leopard 10.6, a 6.5GB dmg file but it always fails with Burn, I don’t have toast so I would like to fine a free way, how can I do?

Can I use the disk utility directly?

I’m using a DVD+R DL 8.5GB


I guess you can just use Disk Utility.app.

  1. Mount the DMG file you want to burn
  2. Open Disk Utility.app
  3. Click “Burn”

enter image description here

But this only works if:

  • your burn medium is not damaged
  • has the right capacity
  • your Mac can write to such a medium

Hold alt and click on the  symbol in the top left menu bar. Then choose “System Profiler”. Go to “Disc Burning” and see which formats are listed under “DVD-Write”. If you are using a DVD+R Double Layer disk and your Mac does not support burning Double Layer disks, you’re out of luck.

You can however “burn” the image onto an external HDD, an iPod or anything of that kind in order to install Snow Leopard from USB.

Yeah, to burn the DMG correctly with Disk utility, I’ve used DVD-R instead of DVD+R.
