OS X 10.11.4 freezing and/or crashing while using Safari

Lexiepex, in your linked article it is explicit said, the problem is not resolved with the Combo Update! I experience it myself, it not does not help!

Nope, You did not read quite well, I did not say it is THE solution, I said it helps often.

combo update did not help me either.for a test, I was just running iTunes this time, the screen was off for power savings, and then it simply froze. I don't think this is related to Safari at all, but some underlying system framework or driver.

Try turning off "Include Safari Suggestions" under Security in Safari preferences.

It seems to be working, and for the record I was experiencing Safari freezes before the 10.11.4 update, always in content-loaded pages.

And, download Safari Technology Preview.

https://developer.apple.com/safari/download/

Works flawlessly. And Safari is working flawlessly since I turned off "Include Safari Suggestions." Safari Technology Preview is a little faster.

I'm currently having the same problem when I click a link with an embedded video. Happened yesterday and today. I installed updates (el capitan) on 3/31 and it was fine. Haven't downloaded anything. Haven't even imported photos.

On 4/2, I made a change to an application's setting. In f.lux, I previously had "start at login" disabled. I manually launched the app as needed and used it without issue. On the afternoon of 4/2, I enabled the startup option. Within a few hours of enabling start at login, my MBP froze for the first time. MBP began to get very hot. Unable to open force quit via keyboard commands. Held power button until MBP shut down. Restarted MBP and worked a few more hours without issue. Shut down (instead of letting it sleep as is my norm) for the night. Restarted this morning. Worked about 30 minutes before it froze upon clicking a link w/ an autoplay video. Forced shutdown again. Restarted. I disabled the startup option for f.lux and quit the app. Made sure autoplay was disabled as per this article: https://discussions.apple.com/thread/6626603?tstart=0.

Long story short: prior to the 3/31 update and enabling f.lux at login, my MBP never once froze.

I don't see that option under the Security tab in preferences. It is under the "Search" tab.

f.lux has nothing to do with this problem.

Having the same issue ..

The problem has started after 10.11.14 update and occurs very randomly while watching videos via Safari. After doing a clean OS reinstall and shifting to Chrome, I have again faced the problem today. I wonder whether it could be a hardware issue or someway software... Please help me to deal with the problem.

P.S. I saw some more people facing the same issue in this forum, just to say Chrome was not a solution in my case.

No, indeed, nothing. The problem is only Apple related and this is why

I've made a clean install of El Capitan, with SSD erase.

Downloaded 10.11.4 combo and installed it.

Nothing more added on the system : no data, no softwares, no turning off options, nothing disabled. El Capitan at totally default settings.

Used Safari, default settings too, no extensions. And started crashing on webpages with videos.

Can't do anything else to prove the problem is only from Apple stuff.

Grimsy, the same issue and the same method was used, having the same issue so far. Somehow I guess the problem connected with hardware acceleration, cause I've experienced the same problem even while using Chrome and clean install...

Eventually, decided to downgrade to Yosemite waiting to Apple's update 😟
