Safari keeps crashing/freezing after install of El Capitan

it does suggest that HTML5 embeds are using a different technique in Safari now that likely addresses the freezes some of us have been having. I'm hopeful.

Fingers crossed! I'll be working through YT a lot in the next few days. I've upgraded.

Been trying to figure out why for the last few months my 2012 Mac Mini has been locking up. Running all kinds of diagnostics, replacing the Hard Drive with an SSD and doing two clean installs. Eventually I began noticing it was mostly locking up when using Safari and now I've found this thread which describes a LOT of familiar symptoms. Upgraded to 10.11.4 and it's already locked up twice. No luck with this update for me so far and just now switching to Chrome to test that out. Have a work Macbook Pro (2014) that hasn't locked up using Safari so it may not be a wide spread issue....

CONFIRMED! APPLE HAS ****NOT**** fixed the YouTube/HTML5 GUI crashes with 10.11.4! 😠

Maybe we should all post YouTube videos showing Safari locking up the entire OS.

It really seems like this is going to take some other action at this point.

Well that's hugely disappointing. Adam, if you have had no fix then I now doubt I will. I'm holding off updating for work reasons (my rush to update to 10.11.3 left more than one piece of software I need unusable until they were also updated) but will report here when I have.

YES. Extremely disappointing. I'm very dismayed by Apple's incompetence here.

Yeah, I was the one who said "Doesn't help" in that thread.

Browserfairy may be a ridiculous way to circumvent an APPLE computer from using the APPLE software that we bought the machines for so that we can use one of the 2 most popular sites in the world:

Has anyone used this app? I'm thinking it will just let us set YouTube links to open in Chrome and leave anything else in Safari.

I also have this problem, when i spend some time watching youtube videos the entire system freeze and i need to restart the computer.

I can confirm too. The issue is still there on 10.11.4.

I will try to disable WebGL, and maybe I'll switch YouTube back to Flash, I hope that will help.

I have a bug report open with Apple and they don't seem to care at all. They suggested I quit Dropbox, but the problem remains. I'm sure that by now they are well aware of the issue, we have pinpointed it very specifically to Safari, YouTube and ElCapitan. They should really have a good idea by now, and yet there is no sign of any progress. This is a serious issue because the ENTIRE system freezes completely for a random amount of time in random intervals, even Force Quit doesn't respond. It's akin to the Blue Screens of Death that plagued Windows 10 years ago.

Update: Turning off WebGL in Safari does not fix the issue. This is becoming completely hopeless.

Yes, it is! I was thinking the same thing when I typed my last comment here.

If it's gone unfixed for 2 years, should we be thinking there's a hardware issue that Apple is ignoring due to their cost to fix it?

On the other hand...if ONLY Safari can't use YouTube, it really seems like a Safari issue.

I'm wary of professing anything too dramatic as lots of these conversations are derailed by hysterical rants and accusations repeated more than the one time needed to make a point. However, with all of that said, I'm still not ruling out a widespread hardware issue. Primarily because Apple is undoubtedly aware that this is affecting a large customer base. Not large enough to make this a widespread story but large enough that plenty of 'me too' replies immediately pop up whenever this subject is raised as a technical question on forums with many saying they've contacted technical support or filed a bug report/feedback. So Apple is aware that this issue exists and probably has an estimate of how wide an issue it is from a better understanding of its minor hardware parts. It's hardly just shrugged its shoulders, no matter what frustrations and silence make people want to believe.

I cannot fathom how it would not have been a Safari update fix by now if it was a problem solely with Safari. Similarly, I cannot fathom how it would not be an OSX update fix by now if it was an issue with El Capitan/Yosemite. This is why I haven't ruled out there's a hardware issue at fault. Apple have previously stayed silent on hardware issues until there was unsurmountable evidence of a hardware issue affecting a large customer base. That's usually the point that the fault was acknowledged publicly. See my post in this thread on the recent Mac Pro announcement as the latest example. Typically there's been complete silence in acknowledging the issue before this point.

I don't think it's worth making all sorts of wild accusations out of frustration from this. It's only a theory and one I'm only basing on educated guesses, not facts. There is also the valid point that this is only affecting a single action in a single browser, which makes a hardware issue harder to believe. So I'm not convinced either way yet.

If anybody working on HTML5 implementation on the open-source side of Firefox and Chromium would chime in that would be incredibly useful. Or those familiar with the deeper levels of WebKit. But that's wishful thinking.

May be its just mine but earlier version of Yosemite had lag, shutter and crash issues in safari. Which went away after few updates. But el capitan has mini freezes in safari with sound and mplayerx(video software) still playing without skipping and is always related to closing a tab or browser with video. Which wasn't the same as yosemite shutters or hang. Anyways i haven't had mini freeze for a while now so hoping it won't be coming back. I am still using safari. Also a lot of sites blame metal graphics implementation for el capitan performance issues. Have a good day.

If this is a hardware issue, how do we get it fixed? The issue occurring probably won't be enough evidence for Apple to replace a motherboard under warranty. I have a bad memory of my previous Mac having graphics issues (MBP randomly turning off whenever the discrete GPU was used) and I couldn't prove that it was a hardware issue because it happened completely randomly, sometimes it didn't happen for a whole month. By the time I figured out what caused it, it was out of warranty, and I was out of luck. That too was an issue that only started happening when upgrading from Leopard to Snow Leopard, which was about a year after I bought the computer so it was out of warranty by the time the issue started happening. But it was still a hardware problem, something to do with poor quality soldering. I just don't want that to happen again.
