Mac OS X 10.3.5 through 10.3.9: Disk images and blank CD-R, CD-RW media, "-536870208" alert in Finder

You put a blank CD-R or CD-RW disc in your computer or attempt to mount a disk image, but the Finder doesn't mount it. Instead, a "-536870208" alert appears. This can happen after updating to Mac OS X 10.3.5 through 10.3.9.

Solution

1. Log in as an administrator.
   
   
2. In the Finder, delete these files:
   
   
   • /System/Library/Extensions.mkext
   • /System/Library/Extensions.kextcache
   • /System/Library/Caches/com.apple.kernelcaches
   
   
   
3. Open Terminal (/Applications/Utilities/Terminal)
   
   
4. Type this, followed by Return:
   sudo touch /System/Library/Extensions
   
   
5. Restart.
