The MacBook Air can share DVD drives on other Macs. For reading disks this works great. However, I want to burn an ISO to the drive. The drive doesn't show up in Disk Utility. Is it possible to burn ISOs onto a shared drive from a MacBook Air?
Try to insert a empty disk into your mac. Then, share it with you MacBook Air. Now, you should have a new DVD-Icon in the finder sidebar.
It should now show up in the Disk Utility tool!
Right-Click on the ISO-Image, and click Burn on CD/DVD after you "connected" the empty CD/DVD to you MacBook Air via DVD-Sharing.
