Safari DNS problem in Yosemite? Works, then slow death...

I have installed the latest beta on my test drive and safari doesn't seem to be experiencing the problem. Ipv6 is enabled, so maybe 10.10.1 fixes the issue.

How did you get the latest beta? I'd like to try it.

I also disabled ad block plus and that sped things up a bit. A shame as ad block plus doesn't cause so much as a hiccup in Chrome and Firefox.

If you want to try it on a secondary drive you can sign up here:

Oh okay, I have used this before when the entire OS was still in beta. So you are getting apps like safari betas pushed to you now that the overall testing of Yosemite 10.10 is over? Or is it ongoing with new versions of Yosemite betas?

Yeah, beta is for Yosemite only. It is now for betas of point updates.

Excellent. Jumping back on that. Hope that helps.

This latest Beta worked for me for fixing the Safari issue! 🙂

I just ran a bunch of benchmark tests all show that Safari 8.0 is "faster" but what the tests say vs what I see in regular day to day surfing, it isn't even a fair fight. Safari is getting pummeled by Firefox. The same with Chrome. These browsers are just smoking safari.

Many of the above suggestions did not work for me (many thanks for the suggestions, though). I tried an ethernet connection instead of WiFi but had the same issue. A couple days ago, I noticed the DNS settings for my ethernet connection were different from the DNS settings (google's DNSes) for my WiFi. I switched back to WiFi, deleted the DNS settings for my ethernet connection, and restarted my computer. The issue has now disappeared for me. No "Safari can't open the page..." issues on WiFi for a couple of days now. Hopefully, this issue won't pop up again for me, and I hope this helps someone else out.

I have installed the latest up date for Yosemite. Works better, but not perfect, and time to time, obliged to switch of wifi and to reconnect. It is not normal from Mac to propose such non workable OS. Not happy at all.

I'm having this issue in my company since I upgraded one of our 20+ MacPros to Yosemite.

• Connection to the company network doesn't work (Mac can't find the servers) *

• Firefox can't find any webpage, even the internal company's sites. **
• Chrome is navigating OK.
• Safari crashes even before opening anything. **

• This issues doesn't happen about 2 in each 10 times that I start a session in Yosemite. Even when everything is OK, though, Safari starts to run slow and then the whole system gets incredibly slow, forcing a restart.

• We're connecting through ethernet gigabit all the time. No problem ever occurred before Yosemite and no problem is happening in any other of our Macs.

• I hoped that the 10.10.1 update would fix that, but I installed it yesterday and the problems still occur.

Come on, Apple, you shouldn't turn your back to the corporate users. We were the first and most loyal of your customers... Please fix that.

* This issue is solved temporarily when I unload and load again the discoveryd in Terminal, as suggested here earlier

** This issue is not solved with the above Terminal command.

I too have installed beta 10.1.1 it seems to fix the problem for wifi. However, when I switch back to ethernet the DNS errors/problems continue. They need to fix it on the ethernet side too.

I have same issue ... many internet connections in the background work fine (downloading tv episodes, remote control of my work PC) but for safari browsing I need to switch wi-fi networks every 30 mins or so when Safari stops loading pages. I setup two wireless networks just for this reason! Weirdly ... once Safari stops being able to load pages I can't even ping my wireless router. I think this is an OS IP level thing ... not a Safari problem.

I just tried turning off pre-fetch of DNS to see if that helps ... I can't do a beta of Yosemite ... so I guess we all wait an update from Apple to fix our connectivity to the world!!!!!!

TThese issues are happening to me as well now. The latest update of Yosemite did little to solve it.

I've been having the same issue and updating to 10.10.1 did not fix it. Also tried resetting network settings, clearing DNS caches to no avail.

What does appear to speed things up for me is to turn off the new Smart Search Field features: In Safari->Preferences->Search, uncheck the bottom 4 checkboxes and restart Safari. I suspect what seems to be long DNS lookups may actually be sluggishness in these features.

Hope this helps some of you out there..

Hitting this issue everyday and none of the suggested solutions have resolved this issue (running 10.10.1). Apple needs to fix this as this is a show stopper if one wants to ever be productive with Safari...
