Q: Safari keeps crashing/freezing after install of El Capitan

After the install of El Capitan, Safari 9.0 keeps locking up and or crashing.

I have a Mac Book Pro 15'' 2.3 GHz i7, 4GB Memory, 500 GB HD, iOS 10.11

 

When using Safari, I will have class work up and YouTube or iTunes playing. Before El Capitan it would do those processes with out a problem. Now it seems to lock up, unable to refresh, unable to exit Safari. I have to force quit and shutdown to try and get control back. Occasionally even after the shut down it will still lock up.

MacBook Pro (15-inch Mid 2012), OS X El Capitan (10.11)

    there's not much precision in the discussion.


    Sporadically, there has been. And those comments were foundations for others for anyone who was following the discussion for a long period with a vested interest. It got to the point where a significant number of us confirmed that similar hardware and all the usual checks (clean install/no pref changes, etc.) could trigger a freeze only when a tab in Safari was switched from or closed that contained the other shared elements that were agreed. Forgive my repetition, I know I'm like a parrot, but I can't help holding significance in that and am a little dubious of a shared cause with the specifics of some freezes mentioned elsewhere here - which does not include yours or alksv's. Perhaps there is a common root fault, perhaps not. Your freeze symptoms were the first I've come across that were so similar and yet had a tiny difference. I'd certainly see a possibility of a shared root cause easier in this case. Especially that the hardware is the same (well, on the broader level of year and screen size at least).


    I remember the specifics of the freeze you were having as we were both discussing it and I was mentioning at the time that it was pretty much confirmed that anyone having the tab triggered freeze was seeing only the GUI stuck and all other processes continued, including SSH ability etc. I believe you were surprised I didn't have multiple computers laying about to SSH into the problem one

    LOL right, you remember quite well the entire history :-) So anyway, I agree that there have been freezes reported that may not share the same root cause.

     

    One problem with so many people reporting symptoms and trying to analyze and narrow to a minimum set of conditions to produce the problem is that many of us aren't equipped to do the same analysis. For example, I can't, at this point, go back to Yosemite or Mavericks (well, I could, because I archived those systems). And others (yourself, for example) don't have a convenient way to try ssh from another system (more on that in a bit). Etc., etc. All of these variables make it very difficult to say whether there's a common thread in what people have been reporting.

     

    On using ssh or some other method to connect to a frozen system, my memory fails me a bit, here, but I think that at one point I was able to connect to the "frozen" mac with Screen Sharing from another mac. Now if you don't have another computer, you can still connect to a Mac with an app on a smartphone (Android or iOS and probably even Windows Mobile). There are apps that can do ssh and others that can do Screen Sharing (specifically using the VNC protocol). If you set your Mac up to allow "remote login" in Sharing prefs, you'll be able to use an ssh app to connect. If you enable "screen sharing" or, preferably, "remote management", you'll be able to connect with a VNC app. Testing with any of these might prove interesting - I don't know what you'll find in your case.

    One thing I noticed following this thread. Members as myself with older MBP's (mine is 2009) seems do not have freezing and slow response problems after 10.11.5 update. I'm sailing with ease and only from time to time, I noticed that by clearing Safari's history (Opt/Clear History to avoid clearing cache) my MBP seems slightly faster. Otherwise, no problems of any sort.

     

    BTW Apple: after Clearing History+Opt, can you secure that previously utilised bookmark icons remain unchanged as in Opera by not returning them to their default blue dot? Just slightly annoying.

    Maybe, but most of us with older MBPs ( i own 2009, 2011, 2012) never had a problem in the first place. So if that is the case, you had another conflict that was not system-board related (e.g.: a 3rd party software conflict).  I have reserved judgement on some small number of 2013-14 machines, but i also have many friends with thsope and zero problems.

     

    Remember - int he attempt to find the problem, a single good example logically rules out that model/sw combination.

    Unless something has escaped me (and this is a looong thread), it appears that those affected are (mostly?) using 2013 or 2014 with integrated (Intel) graphics.

    @Luis Sequeira1

     

    Regarding the Safari tab closing/switching freeze, I believe it's primarily 2014 machines. I can't confirm 2013 but there's a slight chance somebody may have mentioned being affected. No definite confirmations of 2015 machines that I'm aware of.

     

    Not enough collective diagnostics to be sure it's the Intel Iris that's in use when the freeze occurs but, anecdotally, that seems to be the case. I've a 2014 machine with an Intel Iris Pro and and GeForce GPU and it occurs when I'm using the Iris. I can't categorically rule out the nVidia though.

    I do have an iPhone that I could use. As I know the machine is still running processes and the logs produced during this period are available when the GUI becomes unstuck, I'm unsure of what I'd be looking for in terminal if I SSH in, other than the same log files I look at after. I'm not expecting anything peculiar with CPU, Memory or Network but the activity monitor is the only other place I can think of looking. This is really due to my lack of knowledge in various terminal techniques (oh and using an iPhone to communicate with terminal sounds painful as ****).

    You may be right that you wouldn't find anything new that you haven't already seen. And you're also right that doing Terminal on a phone is the worst. I just thought that if you got ambitious and had hours to kill, you could try amusing yourself with that.

     

    If you do take a look at processes, you'll probably see a couple in "stuck" state. Most of these are harmless/irrelevant, and, in general, can be killed without damage. I was at one point able to unfreeze my system and get back to normal operation (and I mean completely normal), but, thinking of what could be going on, that might've been random luck.

    Well, that's a starting point for me anyway. I was going to go back and check what you had mentioned previously as I do remember you describing this same tactic and outcome. Thanks.

    Did anybody experience the freeze without involving YouTube tabs? Mine were all YouTube related. No beach ball and no other system freeze or graphic issues. I use photoshop, Lightroom and very light video editing in iMovie and never felt like my machine doesn't perform as it should.

    I don't know if it's luck or not, but i had no freeze lately, and i don't think it's because of the 10.11.5 update. Having no GPU issues outside of Safari, i don't think it's hardware related.

    Anyway, what would you say the frequency of which the freezes ocur may be? In my case it happened once in 3-4 days.

    Those of us speculating on whether the tab closing/switching freeze may be a hardware issue are only having issues in Safari. Xgrep, with experience working in the hardware industry, believes it is despite the limited scope of software triggering the freeze, so I remain open minded to the idea.


    Did anybody experience the freeze without involving YouTube tabs?


    Since there's a variety of different freezes being discussed here you may find a variety of answers that don't tell you much. For the tab closing/switching freeze I could describe it a little better as a GUI freeze that occurs when a page containing a HTML5 video embed is redrawn or 'undrawn' (not knowing the right term for that). I've described it as switching or closing tabs but I can also redraw or undraw a Safari page by switching to another application while that page was in focus. This has occasionally caused the same GUI freeze.


    In terms of HTML5 videos, I've only noticed it happening with YouTube videos. The only other HTML5 video that gives me odd behaviour is Vimeo embeds which display a glitch-like pattern when they're in an unplayed state, instead of the still image preview they should. Playing them returns them to the normal, expected behaviour. I haven't had one cause a freeze yet but stopped using Safari some time ago.


    If I remember correctly, you mentioned the type of freeze you were having a few months ago and it was just Safari freezing, not the system or the GUI.

    Hey guys i m back. I just had a safari mini freeze(for about 2 min freeze) in youtube tab after over 3 months last night. May be even 4. Only changes i did was use oynx to clean caches an hour before. Also i don't think its only 2014 version. My friend has 13 inch 2013 and my boss has 2012 13 inch both has same safari video tab close freezes.

      3. Clear all the website notifications listed (if any) by clicking Remove All at the bottom.
      4. Go to the Privacy tab.
      5. Click Remove All Website Data...
      6. Once that's completed, close Safari Preferences.
    4. Quit Safari
    5. Reboot Mac
    6. Go into System Preferences > iCloud
      1. Sign back in to iCloud
      2. Make sure the check box is next to Safari

    I get the freeze every few days, usually the New York Times page.  A good incentive not to read the paper at work...  But the fact that this is still not fixed is really shocking.
