What type of Macbook are you using?

I can confirm that this not a MacBook only thing. I get the very same system-wide freeze that eventually causes the machine to reboot on my late 2015 iMac Retina 5K at work. Never happened not once before upgrading to 10.11.4.

Is your system rebooting itself or do you force reboot it manually? Does it create a crash report after you restart it?
 
Happening on my Macbook Air 13" early 2015 when using Safari.
Never happened to my iMac 21,5" late 2012 both of them are running El Capitan 10.11.4.

EDIT: It's a complete system freeze so I can't use the mouse or anything like that...just shutdown and restart with the keyboard button.

You can search online and download the full installer for 10.11.3 (not just the combo update) and do a clean install, it is not directly from apple's servers and usually people don't recommend doing it since it might be a modified version (it might also be agains apple's terms and conditions).

The link you provided gives an expired version of 10.11.3 downloaded before Feb 14, 2016. There was briefly an updated version of it available between Feb 15 and March 20 and many who were unaware of this issue may not have redownloaded the newer version of 10.11.3 which now expires on February 7, 2023. On March 21, 10.11.3 was replaced by 10.11.4 and so the newer version of 10.11.3 can no longer be downloaded from apple.

Nevertheless you can still use the expired version:

If you are in the middle of an OS X install and get tripped up by the expired certificate you can work around the problem quickly as follows

1. In the OS X Installer, choose Utilities > Terminal.
2. Enter date 0201010116 and press Return.
3. Quit Terminal and continue the install.

That Terminal command sets your system date to 1 February 2016 -- before the certificate's expiration -- so the installer can continue. Once you have completed the installation, visit System Preferences > Date & Time to reset the system date.

Spoke to soon....my rMBP has been experiencing this now forcing me to shut down and reboot....youtube causes it every time but no rhyme or reason for when it happens.
 
MacBookPro11,4 here, seeing the system freeze for ~30s sometimes when closing a YouTube video. The whole system becomes sluggish afterwards with intermittent pauses until I restart the computer. Pretty much fits this description over at Reddit. Not sure whether that's what you guys are experiencing as well.

edit - see https://discussions.apple.com/thread/7282267

No, your issue is a separate issue from the one we are having. I think you are the third person to post problems with freezing today that is not related to ours, the one we are having is permanent and it wont unfreeze or restart on it's own, you have to actually press the power button to force reboot it.

My issue is a bit different in that it freezes permanently but restarts on it's own after a minute or so. I also don't have to be watching youtube or whatever, it freezes when I'm not even using it.
 
I am also having this problem, how can i downgrade to El Capitan 10.11.3? or should i just wait until the next update?

edit:
I have just contacted apple on twitter and was told to send them a DM with all the info i had. I just send a DM with the info and also included a link to this thread.

This is the console message I got before my freeze today (1 per day for about 4 weeks now):

23-04-16 16:49:50,000 kernel[0]: process WindowServer[161] caught causing excessive wakeups. EXC_RESOURCE supressed due to audio playback

Antonnn already answered the question in post 195:

Macbook Pro 2015 with OSX El Capitan 10.11.4 system wide freeze

But see also my post 205 pertaining to this:

Macbook Pro 2015 with OSX El Capitan 10.11.4 system wide freeze

Another way is to restore from a backup you made whilst still on 10.11.3 before updating (assuming you have such a backup). Indeed this is an excellent example of why one should make backups before updating the system.

Here is how to make time machine backups and restore from them: http://www.imore.com/how-set-and-restore-time-machine-backup

I am experiencing the same issue on my MacBook Pro 13¨early 2015, random freeze on safari. It never happened before, I hope Apple fixes this very soon...
 
Still no word from Apple? The support forums are filled with people confusing different crashes, are telling them to run a different browser (which won't help).
 
Seems to be a lot of people that are affected by this?! Hoping Apple will fix it soon enough....bought my Macbook Air about a month ago, this little freeze thing was not a nice surprise. Thought it was something wrong with the computer at first but then I googled and saw that it was not just med that was affected by this problem .........totally crazy :S :D

The officiel support board is full of fanboys level10 guys who are trying to find many causes (flash ...) to this problem even when already tried everything, and continue defending Apple by
insinuating that the problem comes from users and not OSX

That kind of guy https://discussions.apple.com/message/30111723#30111723
We already said 100 billion times it freezes even without flash installed, but that kind of Apple white knight will not admit there is a real problem.

So Apple won't fix it quickly if some people are continiously saying that the problem is not from Apple but users.

Apple support forum is a joke. It's full of wanna be kids who think they'll land a job at apple if they reply to every single thread created. It has become the "yahoo answers". Besides, apple's engineers don't check that forum and don't post there, the only thing they do is host the website.

That's why we need to create a short video with tons of macs having this issue and run it on a bunch of websites. Android fan boys and the media love to bash apple so I believe we have a high potential to get noticed.
You don't have to show yourself in the video, you don't have to speak either, just record the freeze and close the lid so everyone can see that the apple logo light doesn't turn off even when you close the lid.

We can't get steps for other people to replicate this issue, so people who don't have it automatically assume it's only you or that you're doing it wrong, I'm looking at you apple support.

I wouldn't be opposed to creating a video but it's so inconsistent on when it happens. Mine does not correct itself. Forces me to hard restart every time.

All you have to do is record with your phone your Mac frozen, when it freezes. Demonstrate that it froze and even closing the lid does not make it sleep. It will be another video in our collection of 10.11.4's freezes.

This time after a week of using Google Chrome , my rMBP 13" Early 2015 froze.

I was watching a youtube video and suddenly it froze.

Do we have any news from Apple?
 
But hey, at least we got new Watch bands!

Right?
Apple needs to reprioritize. The only thing Tim should take from Steve is the whole saying no thing. I know they need new markets and they need to grow etc etc. But they keep pissing off their existing user base by release Watch bands over software fixes. More people and "pros" are moving away from Apple, and the general public will eventually follow. They are on top, but the need to fight more to stay there.

Ok, I filled a bug report, but I'm not a dev. I got a message saying it had been determined a dupe from bug #xxxxxxx but I couldn't click anywhere or search anywhere to check what that bug is. Maybe because I'm not a dev. So maybe the bug was falsely flagged as a dupe, or maybe Apple is aware and they are working on it. There is no way to know, and it is frustrating as hell.

I will record too, should I put video on youtube or send to someone who collects all and merges them in one video?
 
I have experienced this countless times and video taped it where the system freezes and all the keys and trackpad locks up but the music continues and I must hold the power button to turn the computer off.
Does anyone with legal knowledge know whether or not their are any legal ramifications seeing as Apple does not allow you to downgrade and consequently entrap their users on this new software. More importantly, their customer support are not acknowledging that it is a software issue by placing the blame on the customers. So if it can be proven that it is their faulty software, either they must allow their users to downgrade with apples permission or they refund the product. I wonder if the lemon law could apply for all of these users?

I have all the same problems. Don't know if they think it's our fault or not but I will post it on youtube, and I don't have flash in safari or some other extensions so safari is problem or something like that. The need to fix it, we don't pay that much for laptop/pc just to get crash/freeze every other day.

Well firstly, you can downgrade it. Either clean install 10.11.3 or restore from a 10.11.3 backup. See posts 195, 205 and 212 for details.

Secondly if you want a refund for the free 10.11.4 update, that's a refund of $0.
