Hello, I am having difficulty burning a dmg file to a blank disc. I have a macbook pro with OS X 10.5.8. I am using disk utility to attempt this feat but it is being difficult. The blank disc is a 702 MB and the image is ~540 MB. When I attempt to burn the image onto the blank disc, it says the disc inserted does not have enough free space. 1) The disc is blank. 2) The image is less than the capacity of the disc. I tried another blank disc and it still reports the same issue. The blank discs work just fine in Windows and it reports it as such. Why is Mac OS reporting there is no free space when, in fact, there is? Thank you.
