. . . . i think of Project Titan when it is finished as a project and becomes a Core business and the apple self-driven car becomes a reality, with mission critical systems running on apple OS. . . .

Just imagine your car needing a reboot at 70 mph on the freeway. This is the new Apple. If Cook were smart, he sit the software folks down and explain that crappy software releases don't cut it. The problem with that is that Marketing dictates the software releases now, not engineering. Cook does not have the ability or knowledge to force Apple Marketing to step back and Engineering to step up.
 
Hello.

This is a bug. To resolve this bug simply reinstall your graphics drivers on OSX.
For example if you are using Nvidia Web-drivers.
HOW TO FIX
Follow this steps:

.01 click the nvidia icon in the right top corner on your desktop and choose OSX Default Graphics drivers Drivers
.02 Reboot
.03 Click the Nvidia icon on your desktop and choose Nvidia Web Driver
.04 Reboot.

I have a Mid 2011 iMac with AMD Radeon HD 6750M, and I use the heck out of it. Stays ON from 8:00am to 11:59pm unless I need to use it later than that.
I don't recall any freezing since updating to 10.11.4, unless it happened one time a long time ago.

As the article says, could this issue be related to Intel Graphics? Does you Mac have both Graphics Chips?
 
Everything is going well for me.

Hopefully I haven't spoken probs up now :D
 



A large number of MacBook Pro owners running OS X El Capitan are reporting widespread system freezes since installing the 10.11.4 update to Apple's Mac OS.

Hundreds of MacRumors forum members have been posting to a dedicated thread to discuss the issue, which spans 20 pages at the time of writing. The problem appears to be concentrated on 13-inch Retina MacBook Pros (Early 2015) running 10.11.4. Users report that their system becomes totally unresponsive at seemingly random times, with no way to regain access to their Mac other than to force a hard reboot.

The issue was initially reported by MacRumors forum member Antonnn on March 25, four days after Apple released what is the third update to the Mac OS. In Antonnn's case, the freezes have been occurring "about once a week", first when browsing in Safari, but then also during the use of other Mac apps, including Adobe Photoshop and several third-party browsers. The freeze seems to affect not only the screen and mouse cursor but also the Mac's Force Touch trackpad, which completely loses feedback.

Many other users have since reported similar freezes after updating to 10.11.4, with some 15-inch MacBook Pro (Mid 2015) owners also experiencing issues. One potential cause has been identified from crash logs as a system framework or an Intel Graphics driver bug. The issue is also being reported after installing Safari Technology Preview Version 1 and OS X 10.11.5 Public Beta 1.

Apple Support is apparently aware of the issue but have so far offered no concrete solution. Meanwhile, some users have resorted to downgrading their system to 10.11.3 by restoring from a Time Machine backup or performing a clean install.

We'll update this post throughout the day as we learn more.

Owned Macs since 1988. They are computers. Glitches happen. Maybe some of you were not around during the good old days of extension conflicts. Great way to piss away an hour of your life -- but thank the lord for that awesome app Conflict Catcher.

OS X 10.0 and 10.1 were completely unusable -- as public releases.

Then there was the OS X update that erased people's FW hard drives. That one was a hoot.

I've given Apple a lot of crap lately about them become rather boring and undisciplined. No fan of TCCo. these days for sure. This isn't one of those times though. Honestly, this crap is going to happen, Win, Mac, Linux, whatever. These are massive backends engineered by rooms of people. People. Get over it.

This is why you always keep a good bootable back up. Otherwise just click your heels three times and wish you were back in 1901 sipping a Pepsi at the drug store counter watching the parasol girls giggling.
 
Apple is becoming less and less serious about its QA....

but hey, why do products need to "Just work" when you can bring out a Rose Gold color watch band???

I'm getting freezing at work occasionally - 30 to 60 seconds of freeze and then the system continues. Odd. Never pinned it to this current version of OSX.
 
Hi, I have a Late 2014 MacBook Pro 13" and the same issue! Not concentrated to the 2015 model.
 
I have many Macs but I can report my 2010 MacBook Pro 15" is running 10.11.4 flawlessly. I'm guessing it is related to some more modern hardware and if history tells me anything I'd look at third party GPUs first! Of course I could be wrong but I've lost count of Mac issues caused by AMD or Nvidia over the years.

As to the above Windows vs OS X arguments, I boot into Windows 10 and El Capitan (on different drives - not using Boot Camp) daily from a new Mac Pro and have not had a crash on either.
 
yeah, why should software designed for some specific hardware actually work perfectly and not freeze?

That said I have freezes since 10.9 that I guess are related to 4k display connection and sleep / resume cycle.

But why should they ever fix resume without or other display, ... it is not that there would be docking stations for exactly this business use case, ... :-/
--
so now I always try to remember to disconnect any display before I sleep the rMBP at office and home. Yet still once or twice a week I forget this, and then I usually have a frozen surprise to wake, ...

Same issue here with a mid 2013 13" macbook air. I reinstalled OS X and restored multiple times. Apple care kept telling me it was a hardware issue the Apple Store refused to replace any hardware I went back and forth multiple times with no fix. I then decided to erase the recovery partition and OS X from my drive and went from there. Since then everything has been working well for the most part.
 
I've actually been having this problem since updating to the latest os. Didn't connect the dots that it started happening then... I thought it was just one particular website I've been using... Switched to visiting the site on my iPad and it doesn't freeze.... But I have rarely been using my laptop since then, so....

Yeah the computer just completely locks up. No movement on screen. The trackpad doesn't work, keyboard buttons don't work except for holding down the power button. Very annoying... Happened 3 times in less than 30 minutes.

Kind of good to hear it is software related though... I though my 2015 MBA was somehow already breaking. On the other hand, it is another in a long line of Apple failures in recent years on the software front. Like some of you, I also use Windows 10 and it has not ever frozen. I will get slowdowns more frequently than on my Mac, even though my PC is infinitely more powerful hardware-wise, but I've had catastrophic crashes much more frequently on macs in recent years. Kind of sad.
