    I see - sounds as if there's something else amiss.

    defaults read com.apple.safari WebKitDNSPrefetchingEnabled


    will confirm the setting - it is set per user & (probably) needs Safari restarted to take effect.

    it would be nice if pre-fetching was an option to turn on and off in Safari.

    I, for one, agree.

    You can use this form for sending Apple feedback about Safari:

    Thanks, already did before posting. Just reading that thread reminded me that I wanted to do that as soon as it came out.
    For something that can impact Safari so much, it would be nice to control it..at least on or off

    After what happened to Safari a few days ago i will leave it enabled.

    Hi,

     

    first I must appologize, I am a really new Mac user ...

     

    I would like to know how I disable DNS-prefetching for all users per default. Or do I need to run the command above once for every user I have created on my Mac?

     

    I also assume that once executed the command to disable dns-prefetching this will be kept unless I enable dns-prefetching again. And this also if I restart my mac and login again on my profile.

     

    Correct?

     

    BTW: I tried to read the value of WebKitDNSPrefetchingEnabled but this is only working several times directly after having written this attribute to false. After some more repeats I get the following message

     

    >defaults read com.apple.safari WebKitDNSPrefetchingEnabled

    2014-02-27 23:23:39.140 defaults[9167:507]

    The domain/default pair of (com.apple.safari, WebKitDNSPrefetchingEnabled) does not exist

     

    Any feedback would be most appreciated!!!

     

    THANKS

    I've tried to get the plist setting to stick and it always deletes itself as soon as safari starts up. WHY CANT WE DISABLE THIS?!

     

    Safari 7.1.6

     

    I've left product feedback with apple following the link above.
