Hi, I just tried to burn a CD on my iMac's internal drive for the first time since installing Mavericks. I get a persistent message saying "Disk Burner or Software Not Found". This is happening in both iTunes and Toast. I have repaired the permissions using Disk Utility and restarted the software and computer a few times to no avail. Has anybody else had a similar experience, and been able to fix it? The drive is otherwise working fine (playing and importing CDs etc). Thanks for any suggestions or help!
