10.11.4 Safari freeze

I'm having similar problem. Bought my 5k retina 27inch iMac late 2015 on February 24, 2016 on best buy. The computer came with el capitan 10.11.13. I used the computer for many hours almost for a month without problems. I updated to 10.11.14 and thats when the random freeze and automatic freeze started. I have been chatting on apple support for help. Tried many things but failed. They don't want to admit its a software issue. They want me to take it for service at the apple store.

They want me to take it for service at the apple store.

Useless, they can't do anything, because there is nothing to do.

I already Tried a clean install with full SSD erase and updated with 10.11.4 combo, stock install and test with nothing more added to the system, it keeps freezing, so the problem is related to Safari or framework/driver witch came on 10.11.4.

The only solution for the moment is using chrome or firefox, and waiting Apple for a fix, because only Apple developpers can fix it

I have filed a bug report with Apple & provided a sysdiagnose upload.

Hopefully, this will help them move towards a resolution.

The issue isn't whether one uses delta or combo because the issue still appears even for a clean install. I downloaded, created a USB boot drive and did a clean install (formatted my drive) and the same problem occurred. It appears that there may be a bug in either the VideoToolbox.framework or the VideoDecodeAcceleration.framework.

No way Im trying the delete all in the hard drive and clean install. It seems its not working at all for others. I knew it it was a software problem and not a hardware issue. This update is ******* me off. Everytime I turn my computer I always worry when the next freeze will happen. No matter what I'm doing the problem happens. Just yesterday my computer froze and restarted itself while I was listening to music in iTunes with the visualizer in full screen. I noticed another glitch. If you have a headphone connected when turning the computer and decide to disconnect it. The volume keyboard refuses to work. You can't mute, volume up and volume down. It will work if you connect the headphone again then disconnect it. Weird?

You are quite right: it seems that more than usual users have this problem, but many many more don't have it.

For a number of people the combo update helped.

There is also the Safari Technology Preview, a new download. This issue has not yet be seen in this STP as far as I have seen.

Read about it, download it, install it, export the Bookmarks from your standard Safari, import them in STP, set STP settings to your liking.

STP installs separate from your actual Safari.

Try it out.

The reason why more people don't have it is because it only affects certain hardware configurations; so far it appears to only to affect MacBook (incl. Pro and Air) which have Intel GPU although there have been notifications regarding failures on an iMac 5K and a old iMac (ATI 2600 GPU) but that might be related to something relating to a botched update or hardware failure hence their outlier status rather than it being wide spread reported. Btw, the problem occurs with the developer beta of Safari as well - the issue isn't the browser but the hardware acceleration used for video decoding which Flash also taps into but for some reason it appears that the decoder in Chrome some how avoids.

The strange thing is that the latest 10.11.4 beta 15E64a didn't have this problem with Safari or more.

So what the **** Apple dit for the final build, nobody knows ..

Maybe it is related to the security fix that they did for the Intel GPU driver? I'm hoping that they get this fixed up quickly or at least Apple acknowledging the problem rather than the denial mode they seem to be in at present.

I have the Intel GPU and no problems, in several macs.

The STP browser has changes in the webkit inside, maybe that helps.

If not, find the framework files with Pacifist, extract them from Yosemite Installer, and then extract them from ElCap, and compare them.

And you've repeated the same post over and over again. It does not change the fact that those of us who are experiencing freezing are primarily using devices which have Intel based GPU's so it has to have an origin somewhere in the Intel driver itself which is impacting particular models. I have also addressed the issue regarding the Safari developer preview in that the same problem appears which again makes me wonder whether it is entirely unrelated to Webkit but something to do with the Video Toolkit hardware accelerated decoding that Flash taps into given that the flaw occurs both on Chrome and on Safari with the common denominator being Flash.

This update is stressing me out. I regret updating my new imac. I wish I could go back to version 10.11.13 but I dont know how? I already tried os x recovery and internet recovery, It always installs 10.11.4. I did not use time machine I dont want to lose my data. I have been reading online that people have been experiencing the same problem since March 23. Apple sure is taking their sweet time to fix this mess. Others says its a hardware problem and others say its a software issue. Apple sure likes the confusion with the unhappy costumers.

Using Safari with NO FLASH installed is giving this problem randomly, but with one common thing: it always happens while playing videos on the web. So I guess it has something to do with playing HTML5 Video.

"I wish I could go back to version 10.11.13 but I dont know how?"

You can if you have a TimeMachine backup. Don't install a fresh ElCap, install from TimeMacine backup, date before the ElCap Update.

Same here on early 2015 MacBook Pro. Safari on video content causes random freezes. I think, that a lot of users use another browser than safari.

EDIT: There is nothing suspicious in logs:
