Rather than making CD copies, why not create a clean virgin (and updated) When I tried it that way I invariably received an error message that the media was not writable. I would expect this method to also create bootable DVDs but have not yet tried it.īTW, you might intuitively think that opening Disk Utility and executing steps 4 - 6 and inserting a CD would provide the same results but this seems to not be the case. Click the 'Burn' icon at the top-left of the Disk Utility dialog.I made a set of bootable Linux install CDs for PC systems in this way.After Disk Utility opens, drag the ISO image file to the lower portion (below the horizontal divider) of the left-hand pane where disks and volumes are displayed in the Disk Utility dialog.Navigate as you prefer and then select 'Disk Utility' as the desired application to open.When the Finder dialog appears, select 'Open other application' for the desired action.Insert a blank CD into a supported burner.Now that Disk Copy is merged into Disk Utility, this seems to work reliably if you have an existing ISO image: I made a couple of coasters before trying this particular approach. This is simple - but I haven't seen it described quite this way before.
