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

A very good post. Apple appear to adopt a "we cannot confirm or deny there is an issue" attitude that I find unacceptable. I suppose they have enough customers and money to treat concerns like us as they please. Poor business practice.

Try this:

1. Open System Preferences.
2. Click on Network.
3. Remove all of the services in the left-hand pane (Ethernet, Wi-Fi, etc.) using the minus symbol.
4. Click Apply and close System Preferences.
5. Reopen System Preferences.
6. Add back in the service(s) you want using the plus symbol.

This seems to have worked for the network problems I was experiencing (which were intermittent, system-wide and not limited to Safari).

Pages don't load on any browser.

I have read almost all the posts on this issue and find most of them to advanced for me (I'm new with MAC), so I can only agree with you.

Apple SHOULD be doing something about it. Yosemite seemed good but it lasted a few weeks.

I already have 10.10.1 and the problem is even worse.

I need help please !!!

Thank you cyvi937. This has resulted in enough improvement for me to try Safari as my default browser again for a while.

I will report back (and change back to Firefox!) if my problems return.

The worst part of this problem seems to be that for Mac users, the problem extends beyond Safari to other functionality that seems to rely on Safari performance. Yesterday I reported that restarting my Mac cleared the problem for 6 days. Today I woke up to find that the relief provided by yesterday's restart lasted less than one day. Restart still seems to be the easiest way to go until Apple fixes the problem.

I tried removing all network services, closing preferences and re-installing wifi and ethernet. So far this works. Fingers crossed. Other fixes have worked for a bit. Hope this one takes as my only option is to scrap Safari for Firefox.

Thanks

OOkay this worked for me so far but it points to a bigger problem with Safari that needs to be addressed.

Open system stem prefrences and select advanced > hardware.

From rom the drop down menu slelct manually instead of automatic.

Under MTU change the value from 1500 to 1400. Pages that are slow to resolve seem to load faster but I need more time to be sure.

Why the default value of 1500 which was fine in Mavericks and prior systems updates needs to be altered baffles me but again pages are loading more quickly.

Also lso of note on my system, popular pages that update frequently like news sites, send safari into super slow mode prior to this adjustment. It seems like there's a cache issue as well. What a mess.

I have started a discussion on this issue on http://www.mac-forums.com under the title "Safari 8.0 running slow in Yosemite 10.10.1" to see if the users of that site can throw any further light on this subject.

cyvi: Your fix is still working after 24 hours. Thanks again.

Reinstalled - Fresh Install of Yosemite! (Not a Time Machine but fresh)

Removed Network Devices - Re-added

Changed MTU to 1400

No change, it comes and goes!

Apple needs to take action as this is happening to a lot of people..

The DNSFlush works somedays and not others.. My biggest problem is Google searches take 1 minute to complete, facebook doesnt work, youtube if I'm lucky.

I have the same problem and i am not running Yosemite. A couple of days a go I used my wife's Macbook Pro and Safari was unusable. Did a reset, downloaded and installed CleanMyMac2 and ran it, ran Disk Utility and repair permissions. Didn't make any difference. Launched Firefox and browsed to same sites as I had tried with Safari with no problems. Just fired up my iMac, Safari exhibiting the same issue. Same with my Macbook Air. So the common denominator must be Safari. All my macs are running OSX 10.9.5

Better start a new thread and post the link here, explain the issue and tell that you use CleanMyMac, and send an Etrecheck list with it.

Unloadone's solution worked for me right away. I made the change to 1400 before upgrading to Safari 8.02. However, I did not test for worse performance by going back to 1500. Just too much to do.

Might note that even before changes, Safari worked better in other accounts on my machine. The slowdown was occurring in my main account from which I do most of my browsing.

Safari works just fine now.

Thanks so much,

gerry

unfortunately, even after having edited MTU size from 1500 to 1400, nothing changed. As soon as I restarted it seemed to work, but it took me a couple of reloads of the usual sites to start idling again on sites like:

citymapper.com

tfl.gov.uk

even logging back to this discussion was impossible. I had to use Chrome again.

I was hoping Safari 8.0.2 would have solved it, but it seems Apple doesn't want to acknowledge the problem.

Can we do anything to stimulate them? I don't think they browse all the discussions, so it might be useful to organise a way to communicate with them. A petition? An e-mail to Tim? Submitting bugs to Apple has never helped, as far as my experience.

Have you tried the advice of cyvi937 from December 7?

With that and all the other changes including that you mention, I have had no problems since December 7.

That includes the sites you mention.
