Safari keeps crashing/freezing after install of El Capitan

I think these problems started from OS X 10.11.4 or 10.11.3. Before this versions everything runs perfectly. Now i have installed 10.11.5 beta and so far everything is normal. But I use it only 1 day

oh and one more - I've been using a click-to-plugin extension for about a month and since then I had not a single freeze. It's not perfect but at least I can watch a f****ing youtube video during my work without fear of loosing it all because of freeze and force reset.

Give it a try - https://hoyois.github.io/safariextensions/clicktoplugin/

It replaces flash/html objects with default safari player. Sadly it doesn't support 60fps

cheers!

Thank you. Thank you. I will install if it freezes again

I have this issue as well:

I'm on a 5K iMac (late 2015)

I was doing work in Premiere Pro and After effects, nothing else.

And it froze and rebooted itself...

So it's not a Safari issue for me...

Then why did you post about it in this particular thread?

Hi,

I have pretty much the same problem. Only difference is that I can't even move the mouse cursor when the freeze happens. It almost always happens in Safari, interacting with YouTube (BTW, I don't have Flash Installed!), however, there was one instance when it froze during browsing through an article, but a YouTube tab was still open (but not playing at the moment). I must add, and this might be very important, that before I did a clean install of OSX, the freezes were present as well, and once it happened in the Photos app (fullscreen browsing through ~2000 photos, might be an intensive work to do for a Macbook Pro?). I have a 2015 Macbook Pro 13, no dedicated GPU (Intel 6100), and El Capitan. I started my own thread about it, I didn't know back then this one is already here.

@porub

Did the freeze only happen with the 10.11.4 update? There's different freezing issues being discussed in this thread and it's difficult to isolate them in the long discussion. Since you have the problem after a fresh install you can rule out any personal configuration/preferences problems or third party software or utilities causing the problem (providing that you didn't start installing other software and changing preferences before a freeze with the fresh install) and, most importantly, you've cleared all the hurdles that Apple will require if you need to deal with them for support. The reason for my first question is there was a bug introduced with the 10.11.4 update that froze Safari for some people. If so, you've a better idea of what to look out for when researching this. My freezes aren't from the 10.11.4 update so I'm afraid I'm not much more use in that regard.

Unfortunately, I reinstalled 3rd party software, and changed settings in OSX since that clean install. I attach a pic about my app list and the usually runned apps (the freeze can happen when only Safari and Mail is running in the dock). I'm trying Chrome at the moment, and test if it will ever freeze with YouTube or anything. Most of the people have the freezes with Safari though. I'm currently using 10.11.4, but the freezes started to appear around mid-April, I don't know what was the most recent upgrade at that time, but I always updated almost immediately (I bought this machine in December).

Ah, then you can't rule out it's personal configuration files or third party software causing the problem. This should still not happen, absolutely, but if you're dealing with Apple support they'll likely want you to fresh install the entire system without any changes to be sure it's not something you've changed or a problem caused by a different developer's software.

If you can stick to Chrome for a week or two and never open Safari during this time you can be somewhat confident it's a Safari issue (Safari may have been open when you were using Photos). You were likely running 10.11.4 when the freezes happened so look into the 10.11.4 introduced freeze as a first guess for the problem that's affecting you. As I said above, I'm not thoroughly versed in all its symptoms or whether a fix was released so you'll need to confirm yourself after some scrutinising of discussions. I'm also not aware of whether Apple is acknowledging the 10.11.4 freeze at the moment. If they are, dealing with support would be the way to go.

You should run Etrecheck and post its report. Usually it is not the applications you are consciously running, but other stuff like kexts, login items, that you may not even be aware of.

Description:

OSX El Capitan 10.11.4 freezes during interacting with YouTube in Safari or possibly just having it opened in a tab in Safari. System freezes, the time at the status bar freezes, mouse cursor won’t move or respond. Only solution is force shutdown and reboot. This test was done while playing a YouTube video in Safari (only Mail is running in the dock otherwise).

I think the problem is in the OS X 10.11.4
Now i have installed El Capitan 10.11.5 beta and have no freezes since i install.

I see no obvious suspect from the Etrecheck report. You do have a number of login items, and some applications that I haven't used, but they all look legit and fairly recent. Sorry.

I see that FatFrumos has been running 10.11.5 beta and the crashes seem to have stopped, so maybe it is worth a try.

Thank you. I updated to 10.11.5, excited to see what happens. The problem is it's hard to reproduce the "bug", clicking back and forth in YouTube just won't trigger it. It happens randomly in my system, so I wait and see.

What a useless post you wrote. We all know that third party can cause this but we cant figure out which one. For me Yosemite - no problem, El Cap - problem. El cap seems to be heavier on Safari and Safari is not what it used to be before the update.

PS

It froze on 10.11.5 as well. I have i7 macbook pro late 2013.

The best thing to do is to go back to Yosemite or often clean history, cache and website data.

Also guys I noticed the last 2 times the freezing happened, I had very very slow internet speed and Safari was struggling to load some websites and then it froze when I wanted to close tabs. Now I don't know if it has something to do with it but both times that was the case. Can you relate?
