Safari keeps crashing/freezing after install of El Capitan

Hello all. Although i don't really have a solution, i thought i'd share my experience after reading all of your posts. I have a 13'' MacBook Pro Retina (late 2013) and i have been expiriencing Safari freezes since Yosemite. I seems to involve only youtube, today for example i had a few tabs open only with youtube videos and no other app (except safari) running at the time. When it froze i wanted to force quit safari (as i usually do) and reboot, but it came around, with some lag though. So i ran Activity monitor while opening another youtube videos to observe any weird behaviour or memory leak but all seemed normal. By the way, i'm using flash NPAPI Plug-in. Then i did the following:

- Checked that all videos i was watching used html5 and not flash player - they did;

- Updated Flash Plug-in to the newest version;

- Rebooted and ran Activity monitor again while opening a few of the problematic youtube tabs;

- Checked the ''Never check for updates'' box for the flash plug-in.

I also noticed choppy and laggy youtube videos on some channels, especially when maximizing - sent feedback to youtube. Beside this i did not notice any graphic issues or any other problems while running OSX 10.11.4. I would also like to add that i have never performed a clean install - i bought the laptop with Mavericks and updating ever since. I have never had these problems with youtube out of the equation (vessel ran just fine) so i'm not considering a fresh install at this point.

Thanx Tok'ra. Flash is not relevant to the issue in this thread. It does sound like you're having the problem we're discussing though.

5 days have passed since the last time I had the freeze after updating to 10.11.4. Rebooted couple times right after the update, safari was very slow at first when loading favorites, but the freezes have yet not occured.

Although, many other performance issues within Safari still remain. For example, typing a comment on youtube (especially a nested comment) results in symbols appearing with a huge delay. Or slow scrolling on Facebook when you've already scrolled past a few screens (and at some point, the scrolling just stop showing new content -- jerking and reloading existing screen/content instead).

As I see some other users have mentioned the possibility of the crash being caused by a hardware issue. I also see that a lot of us have this happening at their MacBook Pro Retina 13", which makes me feel slightly uncomfortable as I have the same configuration. Would someone care to disprove this theory? I mean, are there people who have had this problem on other machines?

Yes, the same thing happened to me on a 13" MacBook Air (early 2014).

Thanks, Tok'ra. Now I can at least cling to the hope that it's a software bug and that one day they can fix it. 🙂

Mine is 2014 15 inch MacBook Pro. Its happening across a lot of hardware even in iMacs as far I have heard.

Hello everybody!

I'm Thomas from France and this issue also happens on my Macbook Retina 13 inches 2015 (8GB/256GB SSD).

It happened 4 times in 2 days when closing or switching tabs on Safari 9.1 on El Capitan 10.11.4 (15E65).

I'm 99% sure it's related to "FigAgglomeratorSetObjectForKey" and "/Library/Caches/com.apple.xbs/Sources/CoreMedia/CoreMedia-1731.15.202/Prototyp es/LegibleOutput/FigAgglomerator.c line 92" because of the logs I kept.

Something I can find on all my logs at the very moment when the system is frozen:

com.apple.WebKit.WebContent[1827]: [15:42:16.916] <<<< IQ-CA >>>> piqca_setUsePreQueue: (0x7f90a50f1600) rejecting report of layer being serviced - IQ has not yet begun to update

I hope Apple will fix that…

Thanks for the post on this issue. I have been running Macs and, this particular MacBook Pro, for quite a few years with no Safari issues to speak of. That is until recently when it began to crash often and unexpectedly.

I uninstalled a recent load of Flash Play, just tried Safari and a couple of websites and we are back to work!

🙂

Just to keep this on track...THIS THREAD IS NOT FLASH related. This thread is for people having GUI crashing issues with Safari and YouTube (possibly other sites) when closing tabs or windows who are NOT using Flash in Safari. Every once in a while, someone jumps in without reading the earlier posts (no surprise now that it's up to 18 pages) and posts about Flash. It has nothing to do with FLASH (or The Flash).

So, the week after the update and Safari reset, the freezes are back. =(

Some guy (on reddit i think) tried changing the wireless network connection to a wired one after the freeze and stated that safari went back to normal and his problem was dns.

Last night after safari froze, i stopped all its processes and quit safari a couple of times to see if it did anything - it didn't. It seemed to work fine when open, but it was very choppy and slow on different sites.As for dns, i'm using google's 8.8.8.8 and 8.8.8.4. Will try the network thing next.

Just install Safari 9.1.1 and voila... fixed.

Thanks for posting Tarti. Interesting. I still haven't updated to 10.11.4 but am curious to see how others get on with this preview/beta. After some premature 'fixed' comments for the 10.11.4 update I'm not getting my hopes up. Particularly as to why such a big fix would come so soon after the ideal moment of a an OSX point release? I'm presuming that the official release of Safari 9.1 will follow soon after this preview/beta version.
