Computer keeps shutting off - what to do?

[TyrionDraper]

Hi I have MacBook Pro Retina 13inch from Mid 2014. All of a sudden my computer started crashing once every couple of hours, usually seems to happen when I'm surfing around in Safari. Here is the error report:

Does anyone have any suggestions on how to fix this? I am clueless at reading the report. Thanks in advance.

Since it's a model with integrated graphics, and given the data in the log, I would suspect a problem with the RAM or the CPU.

Take it in and have it looked at. Failing that, try to run Apple Diagnostics yourself to see what it says:

https://support.apple.com/HT202731

At any rate, I suspect a hardware problem of some sort.

Thanks for the reply. I'm going to run the diagnostics on it now. If it is a hardware problem, that's pretty disappointing. This laptop is basically a docking station that connects to my monitor at my desk. I barely ever take it anywhere else, sometimes to the couch but I've never dropped it or anything. I suppose since I'm out of warranty I would have to pay for the repairs? That sucks if that's the case.

 

[duervo]

Yeah you'll have to pay. It's a 2014, but I guess technically you could have bought it less than a year ago if it was a refurb. If so, you would still be able to get AppleCare for it, which will probably cost less than any possible repair.

Apple Store will still do a free eval of it, to at least find out what's wrong. You can then go from there.

 

[JohnDS]

Are you using Spotify by any chance? If so, try uninstalling it.

 

[TyrionDraper]

Nah unfortunately I'm not. Hoping it's still a software issue though.

Thanks. I'll have to do that if the diagnostics doesn't solve it for me. I bought it right at the end of 2014 so I'm definitely out of the year period.

If the problem started happening after upgrading to 10.11.3, then there's a good chance you have a pretty common problem. I say 10.11.3 even though you're running 10.11.4 because that's when I started noticing it on my Mini. A lot of people, though, seem to have only noticed it with starting with 10.11.4.

The symptoms are commonly freezing or crashing while doing something in Safari, with the kernel panic report showing "BSD process name corresponding to current thread: com.apple.WebKit" (or it could be Safari, but most commonly it has been WebKit). The kernel extensions it shows are the Accelerator and the Graphics Driver.

I think there may be different problems with the same root cause because some of the people have things in the logs that I don't see. In any case, what helped for me was disabling Flash in Safari, reducing multi-browser use (if you do use multiple browsers at the same time). Some people have speculated that it is the graphics acceleration - while you can turn it off in Firefox, you can't do so in Safari (except for WebGL). I've looked at the other threads that mention this issue (mainly in the El Capitan forum) and there has not been any other concrete steps mentioned - we're all waiting and hoping that Apple fixes this.

It's possible you have some other problem. But if you can run the computer without problems without using Safari or Firefox (don't know about Chrome), then there's a good chance it's the problem introduced in 10.11.3 or 10.11.4.

 

[JohnDS]

Do you still have the problem if you safe-boot by holding down the shift key?

 

[JohnDS]

Often the clue to what is causing the crash is the "last loaded kext" in the error log. In your case this is
com.apple.driver.AppleXsanScheme. I am not sure what this does, but I suspect it has something to do with a network storage device. The last loaded kext before that one is com.apple.nke.rvi which I believe is a network kernel extension. This points to a problem with a network drive of some sort. Are you using something that fits that description.

Perhaps you could download the free diagnostic software Etrecheck http://etrecheck.com and post the diagnostic report back here.

I was actually having problems in Yosemite as well and only just upgraded to El Capitan within the past week. Just before it froze while I was in mail, but it's possible something could've been going on in the background in Safari. Maybe I'll try that with Flash, actually it just updated Flash so maybe I'll see if that fixes it. Thanks for the response!

I haven't tried safe booting so not sure. And I'm not using anything special as far as network drives go. Will try out etrecheck and post back here, thanks.

My history of kernel panics with my 2012 Mini is that I didn't have them with Mountain Lion, had them with 10.10.3 - 10.10.5, have not had any kernel panics in El Capitan until 10.11.3. (Supposedly the .3+ updates are the most stable, but not for me.) In any case, I've looked at my El Capitan kernel panics (5). 4 of them happened in the WebKit process, 1 was in Safari. 4 of the kernel panics happened in 10.11.3, 1 in 10.11.4. The one in 10.11.4 had the following kernel extensions:

which is pretty much the same as what you have, except I have the HD4000 GPU, you have the HD5000 GPU. Unless our computers, which have different models of CPU's and GPU's had a mind meld, I think it's unlikely we have the same hardware issue that would produce such a similar report at this point in time. So I wouldn't panic about the hardware (at least not yet).

(What is a bit unsettling to me is that in my 10.11.3 panics is that the com.apple.iokit.IOAcceleratorFamily2 went from 205.1 to 205.3 in 10.11.4 - maybe a sign that they're trying to fix/screw something up? All the other extensions in the backtrace had the same version.)

The last loaded kext can be deceiving. In one kernel panic I had com.apple.driver.AppleXsanScheme, but I don't have a SAN. Another time it's com.apple.filesystems.afpfs and I don't use the Apple Filing Protocol. Another time it's com.apple.filesystems.smbfs but I don't use SMB. Once there was com.apple.filesystems.msdosfs in the second of the last loaded kext pair and that was common in my Yosemite kernel panics but I don't use the DOS file system (have in the past for some external disks, when I didn't have kernel panics!). According to Apple, a SAN has "At least one computer acting as a metadata controller that combines the RAID arrays and presents their storage to clients as one or more volumes that behave like local disks." You probably don't have that.

Running Etrecheck is not a bad idea. Something may come up there. Post the results and we'll take a look. I haven't run Etrecheck before but I think I'll do that. I think I know what I have on my computer but it's just good due diligence. Like I mentioned in my earlier post, this seems to be an El Capitan issue that seems pretty common.

EDIT: When you said that there was a Flash update, I thought "but I just updated it on March 28" but sure enough, I did the version check and there's an update waiting. It may help (the last one didn't) but I also think there's still something not right with El Capitan in this issue.

My history of kernel panics with my 2012 Mini is that I didn't have them with Mountain Lion, had them with 10.10.3 - 10.10.5, have not had any kernel panics in El Capitan until 10.11.3. (Supposedly the .3+ updates are the most stable, but not for me.) In any case, I've looked at my El Capitan kernel panics (5). 4 of them happened in the WebKit process, 1 was in Safari. 4 of the kernel panics happened in 10.11.3, 1 in 10.11.4. The one in 10.11.4 had the following kernel extensions:

Kernel Extensions in backtrace:
com.apple.iokit.IOAcceleratorFamily2(205.3)[1B6944F0-F0F4-3D26-892C-46EB6C5C7433]@0xffffff7fac9c2000->0xffffff7faca2dfff

which is pretty much the same as what you have, except I have the HD4000 GPU, you have the HD5000 GPU. Unless our computers, which have different models of CPU's and GPU's had a mind meld, I think it's unlikely we have the same hardware issue that would produce such a similar report at this point in time. So I wouldn't panic about the hardware (at least not yet).

(What is a bit unsettling to me is that in my 10.11.3 panics is that the com.apple.iokit.IOAcceleratorFamily2 went from 205.1 to 205.3 in 10.11.4 - maybe a sign that they're trying to fix/screw something up? All the other extensions in the backtrace had the same version.)

I didn't realize these problems were so rampant with OSX / Macbook users. My last MacBook, which wasn't a pro and actually was the last plastic model, never crashed when I used it on Mavericks and every OSX that came before it.

Looking at the report above, I keep seeing:
"~/Library/Logs/DiagnosticReports/com.apple.WebKit.Plugin.64_2016-04-05-143317_[redacted].crash" ??

Something to try (was this already suggested?):

Open the "users & groups" pref pane.
Click the lock icon and enter your password
Click the "+" and create a new, temporary, "empty" account.
Give it any username and password that you wish.
Now, log out of your "main" account and log into the new "temp" account.
Run that way for a while (I realize stuff you normally do won't be there).
Do you still get the spontaneous restarts?

If the answer is no -- problem is -something- "within" your main account.
If the answer is yes -- problem is elsewhere ("in the system"?)...

 

[treekram]

I ran EtreCheck and I must say mine is the most boring results that I've seen. The items in common were the launch daemon com.adobe.fpsaud.plist (2016-04-04) and com.oracle.java.Helper-Tool.plist (we have different versions). I'm guessing that fpsaud is for Flash. I don't think the problem is Java - I haven't that the Java plugins create graphic hardware problems and it's use now by websites is pretty rare.

What I did see is that it seems you're running Chrome. Is that right? There was another person in a thread on the Mac Mini forum who seemed to be having a similar issue and we went through some things and it turned out the commonality between us was that we used Flash and we used Safari and Firefox. One of the things I've done is not have multiple browsers open at the same time and that has helped. (Or, have one browser with only the "boring" page such as the one when one opens a new tab.) Chrome does not use the Adobe Flash plugin and from what I understand it no longer uses WebKit. But if it does graphics acceleration then that's where there may be conflict with Safari - this is pure speculation on my part.

I noticed that with the latest Flash plugin, if there are multiple sites which use Flash (for ads), things are a bit choppy. So maybe they've done something to help prevent problems.

So what I would suggest is being conservative in multi-browser use. You can try and see if the new Flash update helps, if it doesn't, disable it's use in Safari (after every Flash update, it will be activated again). Report back if you're still having problems.

EDIT: I see in the Mac Blog that the latest Adobe Flash update was done for security reasons.

No, I actually I don't use Chrome, I use Safari like you.

You know, since I installed that Flash update yesterday (and I also installed the Flash PPAPI Plug-in and updated Java) I haven't had a crash over the past 16 or so hours. ::crosses fingers:: Have you had any crashes since the update?

 

[treekram]

I have not had a kernel panic since I started doing the strategy I mentioned in my post - disable Flash in Safari, don't have Firefox and Safari open at the same time - don't have too many tabs with sites that rely on Flash advertising (while in Firefox). I use Safari to watch YouTube in the evenings and have done so without a problem (I did a test a while back and Safari was quite a bit more efficient than Firefox when using YouTube).

I have had a crash which produced no log (before the current Flash update) - this happened while watching a video in VLC (this doesn't involve Flash). I'm trying to figure that one out but it will take some time as I need to set aside some time to reproduce the settings in VLC and be able to watch a video for an extended period of time (the crash happened 30 minutes into the video) and test different scenarios. It's because of that crash that I believe that there's an underlying problem in the current El Capitan other than Safari, WebKit and Flash (others have pointed to the graphics acceleration software and I think that's a likely candidate).

That sounds like an intensive strategy which I'm too lazy to implement, think I'll just live with the crashes (lol). I actually did have another crash today, but I think they might be happening at less frequencies. Not sure.

 

[treekram]

I think there was something more than just security fixes in the latest Flash update. Things seems to be working better. I've even started to have both Safari and Firefox open and haven't seen any issues. But it's still early.

If you're continuing to use Flash in Safari and are having issues, one tip I forgot about is that you can disable hardware acceleration for Flash. That will sometimes help.

Go to the following page: https://helpx.adobe.com/flash-playe...type_and_capabilities__Flash_developers_only_

Right click on the graphic with the tree. Select Settings. Click on the left most bottom tab and de-select "Enable hardware acceleration." I'm pretty sure I had turned it off earlier but it was on and I'm keeping it on to see what happens. It might go back on after every Flash update. Strangely enough, the tree graphic will play in Safari even though I have Flash disabled (I tried another site with Flash videos and Safari wants me to activate the Flash plugin to play the video so it is properly disabled).

Thanks for the tips. I'm experiencing the same as you, I think the Flash update might have fixed a lot of the problem. As I said, I did have one crash, but that's only 1 in greater than 2 days.

This issue, besides kernel panics, would cause freezes and stalls (beachball) in both Safari and Firefox - which it doesn't seem like you had - which I could clear up by killing the Flash plugin for Firefox (so yes, killing the Firefox Flash plugin would un-beachball Safari, which has the Flash plugin disabled). I also haven't had that since the latest Flash update. I think one reason why symptoms and solutions are fairly similar between us is because your MBP uses the HD5000 GPU, my Mini uses the HD4000 GPU. A majority of the Safari freeze posts that I'm seeing seem to be a bit different in the symptoms so if they have a different GPU, I don't know that the same solution would work. For example one poster cited not being able to use YouTube in Safari (YouTube no longer uses Flash). I haven't had problems doing that even with the freezing, kernel panics, etc.

 

[treekram]

In the last day, there have been a couple of other posters who have kernel panic reports similar to what the OP posted here and I've directed them to this thread. One person is running 10.10.5 and there have been numerous reports of problems in 10.10.5 since the Safari 9.1 upgrade.

In the last week, I've gone back to using Safari and Firefox the way I was using it before the freezes and kernel panics. I've had one kernel panic, a freeze and a bad slowdown since then. I was in Yahoo mail in Safari when the last kernel panic occurred. There was also a previous kernel panic that occurred when navigating back to a Yahoo mail tab in Safari. I moved my usage of Yahoo mail to Firefox. There was a freeze. Now I don't keep Yahoo mail page open - I reopen the mail page to check mail periodically in Firefox (if you don't log out, the cookie will keep you logged in to your mail session). The Yahoo home page seems to cause issues (slowdown, one thread at 100%) in Firefox since I still have Flash enabled there. I now use Yahoo (minus mail) in Safari, where I've disabled Flash. I think there's some timer issue in the Yahoo pages. The mail page probably has a timer to refresh the mail and timers to refresh the ads. In the last 5 days or so, since taking these actions, I haven't had these problems and I go to some pretty busy (content-wise) web pages.

For others having issues, see if there's a pattern to the websites you're visiting. This is a PITA but until there's a fix, for me at least, it's a better alternative than kernel panics, freezes, etc.

After the previous post, I found a couple of interesting issues yesterday.

First, I was reading an online article in Safari from one of the PC* magazines (PCWorld, PCWeek or whatever). The page did not at first have a video. Then the middle of the page opened up and played a video ad. I right-clicked and it was a Flash video - playing in Flashed-disabled Safari. I checked and Flash was still disabled. I checked another website that I know has Flash videos and it said I needed to take action to enable Flash to play the video. So either some ad providers have found a way around disabling Flash in Safari or Safari isn't very good at disabling Flash or Flash doesn't always listen when Safari tells it to disable itself. Or maybe there's a Flash that doesn't require a Flash plugin. In any case, there wasn't a problem in playing the video but I closed it pretty quickly.

The other issue is also interesting. Once a month I process some data - this uses a web app that I wrote. Whereas I haven't noticed much difference (when there aren't issues) in the latest Safari upgrade, in this case, my web page was giving Safari some fits which wasn't there in the previous version. My page isn't complicated - it's just contains an HTML table - it's that the page is very large with a large number (over 9000) checkboxes. It looks like Safari got overwhelmed and for a little while I thought maybe it was going kernel panic. I need to do more testing on this. (For context, I've done this monthly processing for years - starting with a 2005 iMac running Snow Leopard and while some versions of Safari have worked better than others, it was nothing like what I saw with the current version.)
