The Safari freeze issue, lets fix this

Im so sick of this problem.... would installing Firefox or google chrome fix this? Its gotten to the point that I'm terrified to brows the web on my mac. I even wasted a ton of time doing a fresh install and setting up everything fresh... worked for a few months and then started happening again.

Just switched to Firefox. We'll see how that goes. Luckily this machine can be used as a monitor for when I get a new computer
 
I just updated to 10.12.2, hopefully, as someone else said, this version fixes the issue. I have firefox as my default, change is difficult.
 
Safari turns itself off on my Mini. If I leave the computer for a while I come back and safari is off.
Doesn't do it on my older Mini, just my 2011 Mini. Cannot figure out why
 
Taken from https://discussions.apple.com/message/31166261#message31166261:

Hey guys,

I have maybe found a solution to use our lovely Safari without freezing of the system. Follow these steps:

1) close Safari.
2) In the Terminal app, enable the debug menu of Safari by executing this command:
Code: 
defaults write com.apple.safari IncludeInternalDebugMenu 1
3) Open Safari and in the debug menu go to "Drawing/compositing flags.
4) Choose "disable canvas accelerated drawing" and "disable full page accelerated drawing".
5) Test it.

In my case, it looks like that the freezes stopped. Usually, by using Safari for few minutes I get a freeze.

Let me know your experience.

Finally, I really think that there is a problem in the graphic components of Sierra. But something is intriguing me. This bug looks quite straightforward, I mean it always occurs with the use of Safari and its origin looks obvious. Therefore, why it takes so long for Apple to fix it?

Gonna try it.

What about the Security Update 2016-003 Supplemental for 10.11.6 from 17.01.2017 .

https://support.apple.com/kb/DL1908?locale=de_DE

Apple wrote in the update notes:
"Update fixes a kernel issue that may cause your Mac to occasionally become unresponsive."

This sound a bit like the freezing problem we facing with since 10.11.4 . But how knows, maybe the just referencing to a different problem?

Did someone try this last update with El Capitan and can share some experience here?
 
That sounds promising. Maybe i will let my iMac come out of retirement and test it out too. It only took a year for a promising solution :D
 
It gets a lil laggy on cpu intensive webkit stuff but I still only have 4gb RAM so that may be just that.

I understand, and I do not expect that to work. "Remote Login" in the Sharing tab refers to SSH, a command-line interface that should work even if your screen is stuck. Think of it as remote Terminal. If you are not familiar with Terminal then it may not be of great use to you - but in a pinch you could log in and type:

sudo shutdown -r now

and try to reboot the machine cleanly without having to power it off.

I have tried this, and the machine will not reboot. nothing works but the power button. Safari is the main culprit, but it will occasionally lock without Safari.

Yeah, i started up my iMac again after a couple of months retirement and i tried the fix and so far it have worked, i have almost 3 weeks of uptime now, over 1 year since i could get that uptime without any freezes.

Such a shame that the backlight on my iMac doesn't work now that we finally have a fix but on the plus side, sometimes when i wake it up from sleep the backlight starts working for a minute or so; so i can enjoy a nice Philips Ambilight style backlight behind my ACD ;) (i wonder if it is worth trying to fix the backlight but i guess its expensive as ****)

Anyways, nice that there is a fix that works, FINALLY

I recently ran into this problem after the 10.12.4 update. Safari would crash on this one page. Only a hard shutdown would solve it.

I found that by turning off JavaScript, it would solve the problem. It's not a real solution though as just about every webpage out there uses JavaScript. None of the other browsers (Chrome, Firefox, Opera, ect.) were having this problem on the exact page that would crash Safari.

After some searching, I found one person who posted a crash report and it appears the the JavaScriptCore was crashing. In my opinion, I think Apple's new JavaScript engine which was supposed to make JavaScript run faster is the culprit. Just a guess though.

Still, I can no longer use Safari. Now I have to move to another browser but each one has their own issues. I guess I have the choose the one I have the least objections to. Fun times.
 
Not sure he has the same problem as us, i have not seen any evidence that the javascript engine is the reason for the "crashes", i've turned off javascript a billion times before and still got the freeze. The only fix for me has been the solution that superduperultra posted/linked, not a single freeze since then.
 
I tried disabling the hardware accelleration and it didn't make a difference. Only the Javascript. Once they updated the Safari Technology Preview that I also have, the problem finally went away. It appears they were tweaking some things and something got out of whack.
 
Meantime Safari times itself out and quits even when a download is in progress.
No way to get it to stop doing it either as far as I can see.
