I shut off DNS prefetching to test an internet performance problem that I'm having....


I then tried using the command:


defaults delete com.apple.safari WebKitDNSPrefetchingEnabled


....in a Terminal window to re-enable DNS prefetching and I got this message after hitting enter:


2013-11-18 20:21:24.479 defaults[359:507]

Domain (com.apple.safari) not found.

Defaults have not been changed.


Any idea what this means?  Am I to assume that because of this error that DNS prefetching has not been re-enabled correctly?
