I purchased iMac and had a clean set up. I have Orcon (in NZ) my internet service provider. I have all updates done properly. Why my Safari won't load any google related sites after a while? It started a couple of days ago and I cannot figure out why. I didn't change any network settings or anything. Google just won't load, blogger won't load. google analytics won't load... I need to restart my iMac and then it works a while unitl Google won't load again... Does anybody have an answer? This is getting very frustrating. Thank you.

    Only Google pages? What exactly happens when they fail to load?

  • Mariusariel Level 1 Level 1 (0 points)

    Only Google pages. The loading stops halway and the page remsins as a plank white page. Sometimes it's gray with a message that Safari cannot find the server. Weird.

    I used the DNS server settings from Google:

    IPv4 settings 8.8.8.8 and 8.8.4.4 and then I also put these IPv6 settings just to be sure

    • 2001:4860:4860::8888
    • 2001:4860:4860::8844

    It seems to work. at least for now. Fingers crossed.

    I wouldn't recommend that you keep those DNS settings permanently. There are both privacy and technical reasons why you might not want to. The problem with your ISP's DNS servers may be temporary. I suggest you revert to them in a few days and test.

    Hi Linc, thank you for your comments. Whaty kind of issues your are talking about? I am not very familiar with these technical aspects and I would like to know more.

  • Linc Davis Level 10 Level 10 (153,455 points)

    This is a comment on OpenDNS and other public DNS services, such as Google DNS.

       

    First, DNS simply resolves the human-readable name of an Internet server, such as www.apple.com, to the numerical address by which that server can be reached. The process is analogous to looking up a phone number by name. There is no chance that changing DNS servers will have any effect on a network problem not related to name resolution.
    There are two valid reasons why you might want to use a public DNS service:
    • The DNS servers provided by your ISP are misconfigured or don't perform well.
    • You have a use for the filtering controls provided by OpenDNS and others.
    Although some DNS services are often touted as being faster than others, there's no evidence that the claim is true in any meaningful sense. Most likely there is no noticeable difference in performance among the DNS servers available to you, and under some conditions public DNS will significantly slow down network performance.
      

    Content-distribution networks, such as the one used by Apple, rely on the location of the DNS server to optimize performance. If your query goes to a distant DNS server, you may get slow downloads of Apple content, among other things. This issue is more likely to affect you if you're outside the U.S.

     

    Why using Google DNS / OpenDNS is a bad idea

     

    ISP's do not intentionally redirect valid DNS queries, though it sometimes happens because of a misconfiguration. Your ISP may, and OpenDNS certainly will, redirect invalid queries to ad sites, in violation of published standards for DNS.

     

    The claims on the OpenDNS website that it "blocks" malware attacks such as Flashback are false advertising. A name service does not and cannot block anything. All it can do is to selectively block queries. It's trivial for a malware attacker to evade such blocks. It's just as easy to evade the parental controls offered by OpenDNS. You may consider those filtering features useful, despite their limitations.

     

    There is one exception to the rule that OpenDNS and Google DNS don't improve performance. The "prefetching" performed by modern web browsers, including Safari, may confuse some DNS servers, with the effects described in this Apple Support article:

     

    Slow or partial webpage loading, or webpage cannot be found

     

    The article suggests testing OpenDNS, Google DNS, or another third-party DNS service as a possible way to overcome the problem.

      
    If you need to switch DNS providers because of a misconfiguration of your ISP's servers, the change will most likely only need to be temporary. The problem may be resolved automatically within a matter of hours.
      
    If you intend to use public DNS on a long-term basis, you should be aware of the privacy implications. As a user of the free service, you are not an OpenDNS customer, and the company  — a for-profit corporation — doesn't have a contract with you. The marketers to whom OpenDNS sells information are its customers.

     

    OpenDNS will know, and store, the address of every Internet server you use from now on. This is from its privacy policy:
    When you use our Services, OpenDNS stores certain DNS, IP address and related information about you to improve the quality of our Service, to provide you with Services and for internal business and analysis purposes.

    Concerning personal information, the policy states:

    ...[I]t is disclosed to entities that perform marketing services on our behalf or to other entities with whom we have joint marketing agreements...

    You can't opt out of those disclosures. Read the privacy policy carefully and draw your own conclusions. The privacy policy of Google DNS seems to be somewhat more benign, but again, you should decide that for yourself.

    Thank you for taking time to answer me. Much appreciated.

    I solved my Google and mail problem with the help of Apple Support. The real poison that prevented me doing things was a corrupted preference file that this fantastic support person was able to help me locate. I have been talking with many kinds of IT support but Apple is the best by miles.

  • Linc Davis Level 10 Level 10 (153,455 points)

    Which file was that?

  • Mariusariel Level 1 Level 1 (0 points)

    it was com.apple.mail.plist

     

    now it seems that all the problems have gone.

  • Linc Davis Level 10 Level 10 (153,455 points)

    I'm glad to hear your problems are solved, but for the sake of anyone else finding this thread, deleting that file couldn't possibly have had any effect on Safari.

  • Mariusariel Level 1 Level 1 (0 points)

    Yes, this is very strange. Now I have been using both Safari and email without any problems. The only thing that I can think of as a change (except deleting my mail accounts, deleting the preferense plist and building them again) is that I disabled firewall that was on my interent providers modem settings...

  • Linc Davis Level 10 Level 10 (153,455 points)

    That makes a lot more sense.

    Hello,

    I have a similar safari/google issues, but no issue with my email.

    You seam very knowlegable, maybe you can help me.

     

    Since I bought the Macbook pro retina 13inch I can't access google service and youtube anymore. It never worked on this new laptop.

     

    - Youtube

    - google maps

    - google translate

    - google play

    - google books

    - etc.

     

    It's only a problem with Safari, as soon as I use a different browser like Opera or Firefox, everthinks works.     If I use Safari I get the message:  "Safari can't connect to Server"

     

    I'm searching for a while for people with the same issue but I was not able to find anything.

    Some tipps like run safari in 32 bit mode, rest safari, delete all cookie, check host file for redirecting ip entries, all this had no effect.

     

    would be very glad if you could help.
