Hi. I have a .dmg file that I want to burn to a DVD. The file is about 6.9 GB, too big for a normal DVD. I've tried everything I can find out to make this work, but without success. I've tried compressing the file (right click and compress, but the zip size remained the same size as the original). Disk utility won't even recognize the volume. Can anyone help?
Does your superdrive support dual-layer DVDs?
Disk utility won't even recognize the volume.
Are you saying it doesn't recognize/mount the .dmg at all???
I don't know if my lapbook will support dual layer DVDs. It's an early 2009 13" MacBook white (not unibody). Is it too old?
When I go to disk utility, the .dmg image file does not show on the LH column, nor can I drag it there.
"I don't know if my lapbook will support dual layer DVDs. "
Mactracker says it does:
MacBook5,2 (early 2009)
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)
The DL is dual layer.
Is your disc dual-layer?
Did you buy high quality discs as indicated by this tip*:

Might you need to copy the contents of the DMG to a Disk Image formatted as a CD/DVD master disc image? Disk Utility has that as an option to create images that are.
