OS X 10.11.4 freezing and/or crashing while using Safari

THanks for the suggestion, I've just ran the hardware test, did the thorough test too, it came back ok saying no hardware problems.

Bee and cdhw,

It seems that Flash Player was causing my "freezing" issue. The very last version of Flash Player (21.0.0.213) was showing as installed on System preference but an earlier version of Flash Player somehow appeared to be used by Safari. I have no idea how this happened, possibly a corruption of some sort during the latest update of El Capitan.

What did I do? I had to uninstall Flash Player fully, using the Adobe Flash Player uninstaller. I ran without it for a few days and no freeze occurred. I re-installed Flash Player yesterday as it is needed on some websites and I remain "freeze free". It is however still early days to say that the re-installed Flash Player is "freeze-free" but so far so good.

Cool!

Keeping everything crossed for you, L!

🙂

I too have installed the latest flash driver. I had no flash at all before as i had formatted my hard drive and re installed el capitan from fresh. So i have just put the latest one on from their site.

Mine is running ok at the moment but it's only been hours so far. Fingers crossed.

Not sure it's Flash related last time it happened i wasn't using safari and flash player is deactivated anyways.

iam going to crazy very soon.. just freezed 3!! times in a row in 10 minutes.. every time caused by watching (just started to watch) a youtube video via safari.

apple do something !!!!

Just sharing:-

I have exactly the same problem after 10.11.4 update on imac. My computer crashes and it just try restarting on it's own for about 6 times and more. I have to unplug to stop it restarting.

I have been on the phone with apple senior advisor since last week. We have try everything and finally they advise me to wipe out my hard-disk to reinstall. However, I wasn't able to do that as it seemed my imac cannot connect to the internet after the crashes. This turns out to be a blessing.

The next morning, I try 'command R' and it manage to revive again for a couple of hours. I suspected it's safari but no proof. Since then, it can restart erratically occasionally, I was certain there's has to be other fixes without wiping out my hard drive!!! Can you imagine one has to do that!

After the update, all my devise, laptop, ipad, iphone started experiencing problem signing into my wi-fi. It keeps asking me to select network and sign-in with password every time the device log into wi-fi.

Back again to Apple advisor and they assured me, my setting was correct. However I felt there's some conflict in the setting, that is why the imac can't connect to the internet to do a hard disk recovery. Lucky for me, otherwise it would have wipe my hard disk and I have to reinstall everything again.

I then went to changes a couple of settings in the Airport Utility and voila I have no problem with all the devices automatically login.

I set google chrome as a default browser to stop safari opening in my imac. With safari out of the way. My iMac hasn't crash for 8 hours today. Finger crossed. I hope it last.

FWIW, there is clearly a problem with Safari and OS X 10.11.4. The best idea is to use Firefox or Google Chrome until it is sorted out.

The same problem here... It's super annoying. Macbook Air 13' (early 2015) and the issue starts when I update to OS X El capitan 10.11.4 and using Safari. I'm trying to use google chrome but isn't a solution.

No, it's not a solution. That has to come from Apple as a future update.

Great explanation! Never expected it but it works!

Nothing works. I've tried changing browsers. Firefox runs very hot in the CPU and eventually complete freezes.

To those of you suggesting all kinds of complicated fixes: THIS IS NOT WHY WE USE MACS.

Apple is starting to resemble VW with its refusal to address its diesel problems.

You should start your own post then. This thread is about those having problems with OSX 10.11.4 and Safari freezing. Apparently you have a different issue if Firefox causes you Mac to run hot. You will not get much help if you post to the wrong thread.

i am running 10.11.5 beta 1 for a few days now, nothing has changed. I even get freezes now without any browser open, no flash installed, and the computer more or less idling with the screen off and just some itunes internet radio playing. RAM usage is at about 8GB (of 32 total). Hardware test fine, memtest OK. Since Apple is reportedly working on Metal and the underlying graphics framework in order to leave their neglected and slow openGL-implementation behind, I currently suspect a driver issue.

I've the same problem with Safari and Safari Technology Preview (MacBook Air early 2015 - OS X 10.11.4)

In addition my macbook is very laggy while it automatically adjust the brightness, so I have to turn off this function.

IMHO the best solution is go back to 10.11.3
