OS X 10.11.4 freezing and/or crashing while using Safari

now on 10.11.5 beta 2. ran for about 2h youtube/chrome, then froze again.

xjx, et al . . .

Adobe updated Flash yesterday, which is specifically upgraded to address freezing issues in Safari.

It has helped many already.

It's version 21.0.0.226

I'll never install Flash player...

I agree, xjx. It's not an answer to all. But it has given me hope, seeing that it helped some other very experienced users.

I really hate to open my mouth and break the spell.....

Today, I uninstalled Flash using Adobe's uninstaller. Then I did a command-F search for "flash." Yeah I'm old school and didn't use Spotlight. 😁

It found a Flash plug-in the uninstaller missed somehow. I trashed that. I've been trying to make Safari crash, going to the type of website that was crashing Safari and causing it to only partially load pages. I haven't seen a beachball or a partially loaded page yet. But I have a question for minds wiser than mine.

How is Safari handling Flash content now? I mean, what is it using as I have no Flash installed?

Thanks!

It's been a whole 12-14 Flash-free hours now and not a crash, and Safari is snappy quick like usual.

I don't have Flash Player at all (never installed since last "fresh install" of OS X) but there's always rainbow wheels, blank pages and everything freezing for a few seconds.

HTML 5 sometimes runs really slow (MBP late 2008...) but this bug happens also on pages like Google search and others without media contents.

Re: 2011 iMac 27

All went well for about a week and I was even able to work in my Illustrator and cleanup my desktop thinking it would help to trash all junk. The only use chrome the entire time, hoping for a fix in Safari to come soon. And it happened to while I was in Chrome as well. It went down again for a few days unable to get it started. Today I manage to restart it for a short while and it goes dead again after I open iTunes.

I do not have any problem with my Macbook Pro 2014 Retina.

I think it only happened to some older Mac as the first thing the senior advisor asked was the model of my Mac.

There are so many thread on this issue that Apple clearly knows. I encourage as many people to call in so they will find a fix. I am lucky to have a laptop for minor word processing but all my stuff is in my desktop.

I am back to square one that it will not restart now! My patience is running very thin! I switch from PC to Mac to avoid these problem and it seemed Apple is resembling PC now in a more expensive version.

This issue has happened to me a few times since I purchased my early 2015 rMBP 13" this summer. I'm not sure when it began. This happened earlier today to me, so I decided to do some researching of the issue. Upon hearing about Safari as a potential culprit, I closed it. I was playing an .mp4 file in quicktime and while scrubbing, the freezing occurred. It happened exactly like everyone else...screen freezes, keyboard and trackpad are no longer responsive, and the only way to get it back to normal is a powerdown and restart.

I honestly don't use my rMBP that much...I have a crappy lenovo for work. I can only imagine that if I used this computer for work that my life would be a living nightmare. This is totally unacceptable.

What version of OS X are people reverting to where this issue no longer remains? I am seeing reports that 10.11.3 is doing the same thing. Should I go back further until Apple sorts this thing out? Can anyone confirm that using TM to go back to 10.11.3 fixes the random freezing?

now on OSX 10.11.5 beta 3, crashing/freezing has become even less predictable. sometimes the system lasts for an hour, sometimes it crashes within the first few minutes, even without any browser open and without flash. i can't work this way.

I have exactly this issue. It happens with Safari mostly. Once with the notes app (but Safari may have been open in the background, but no windows actually opened). Once it happened in Google Chrome.

I need a fix for this ASAP. The apple folks suggested a full restore of the OS. That didn't help and it actually made the problem more noticeable.

I am having the same exact issue (retina macbook pro 2015), except that it freezes when i'm running iTunes (I use firefox as my web browser and no issues there). iTunes had an update at the same time, and i tried downgrading that, with no success. So I next tried re-installing the 10.11.4 combo installer, it did not solve the issue either. I had NO issues prior to this update, and now it's half a dozen re-starts a day, and it definitely appears it was the OSX 10.11.4 that started it (not itunes or a web browser).

I have tried all the normal disk repair, PRAM, etc.and even took it to the genius bar (and they just scratched their heads and didnt have a clue).

I have a late 2015 27" 5k iMac and have had frequent freezing since installing 10.11.4 in all kinds of apps from running VLC to just watching videos on Vimeo and then my work with Premiere Pro. Same as biochem_researcher with ZERO problems before this update. Really can't work like this...PLZ FIX!!
