10.11.4 Safari freeze

I haven't tried this yet, because it is annoying to use such a convoluted process, but this should let you revert back to 10.11.3, which never had any of these problems, at least for me:

1. Make a Time Machine backup of your disk.

2. Use TM to do a full restore of your system from a backup BEFORE you "upgraded" to 10.11.4. For reference, 10.11.4 was released on 3/21/2016, so a backup on or before that date should be okay to use.

3. Step 2 will also, unfortunately, revert all your user files to the state they were in at the old TM backup, so:

4. Now use the TM backup made in step 1 to replace ONLY your home folder.

This should give you a 10.11.3 system and all your most recent user files.

As I've stated before, this is an annoying work around. TM should have a "restore only system files" option. Apple should also stop deleting the earlier versions of the OS, or we can all learn to save things like the 10.11.0 full installer so we can revert to interim updates like 10.11.3 as needed.

It would be even better if Apple would just FIX THE PROBLEM, but they haven't done that yet.

Exactly the same problem using exactly the same device: macbook pro 13" 2015. A problem which started happening on the update of 10.11.4 surely but I am not sure if it did it as well in .3 ...still now its more frequent and its bizarre.

Hopefully Apple takes note and fix this since its VERY annoying. Reminds me of my previous Windows computers and I am not liking it :/

"Hopefully Apple takes note and fix this since its VERY annoying."

They MUST be aware of it since they took the trouble to remove a post I made about this issue and some beta software. I'd really appreciate it if the same effort that goes into policing the discussion board was applied to fixing critical software bugs.

I've had this problem for a long time on my Late 2009 iMac. It predates El Capitan, I think it may have started it as far back as 10.9 but definitely by 10.10. It is almost always accompanied by this system log message:

Apr 14 23:49:12 Macintosh watchdogd[179]: [watchdog_daemon] @(_wd_daemon_service_thread) - service (com.apple.WindowServer) reported as unresponsive

That message doesn't always appear; it didn't appear the most recent time which was when I was running Safari Technology Preview.

Having this exact problem too - happens in anything though, not just Safari as others reported. Just glad for now to see that I am not alone and that it's software related apparently. Annoying AF though, ****, Apple really needs to get their act together and fix this.

Another one affected here. Anything I can do to make Apple more aware of this?

They are. But since it's on OSX and not IOS (iPhones are a best seller than all the Macs models together), and because it does not affect everybody and all Macintoshs, it's not urgent for them.

They'll fix it probably on 10.11.5 final build in 2 or 3 months, but do not expect a quick special fix for this single problem.

Well, today I was talking with apple care and told me that It's a error with Java in Safari and that we need to stop freezing is desable javascript in preferences. I don't know if someone use that and if that's works. Anyway when you do that you can't view pages like youtube o facebook. Safari is wasted.

Wait. Java and Javascript are too different things. So, which one is the problem?

Second, disabling Java or Javascript is a fix along the lines of "Doctor it hurts when I do that. Well, don't do that!"

Yes, I know, I told them that is a stupid solution because we need a new update that fix this problem. They told me that the problem is with javascript but I dont believe anything because I was talking with 3 different agents and they told me different things. I'm trying this solution disabling javascript in safari, I tell you how it's going on.

Agree. How is it even possible not to use JS? Second - I don't have Java installed at all, and, btw, how could it be related with Java Script, when it freezes up in Photos app, for example?

Support's just ignoring my questions. It's weird.

I told them that is impossible not use JS and their recomendation is use another browser, i'm using chrome but is not a solution. I think support is ignoring us.

Hi,

I had the same problem again, yesterday. Full freeze of the screen while watching a youtube video. I had it the first time a couple weeks ago in Netflix.

My brother has the same problem which appears randomly. We have both an actual MacBook Pro/ Air with the intel graphic chip and using Safari with no Flash and Java installed.

I also checked the messages in console but cannot find any errors etc. But my assumption is that it depends on the graphic driver which crashes because of the fact that the OS recover every window and application after the forced reboot. So the Mac is reacting at all only the display is freezed.

I hope Apple is going to fix that very soon. I don't want to use an other browser because Safari is almost the fastest browser on a Mac.

This is getting frustrating. I would like a recognition from Apple at least. It's not javascript, it happens with or without flash installed. It's something in the graphics drivers of the intel chips, or the frameworks safari uses to accelerate things. Memory use goes up dramatically when view webpages with a lot of animation in them, like Apples own pages for example. Then the system just freezes, requiring a hard reboot.

This is what all the crashes have in common.

Someone has tried reinstalling OS X El capitan 10.11.4? I think I'll do it to see if that resolve the issue.
