System spontaneously reboots under Yosemite

I had no problems upgrading from Mavericks on my MBPro 13" retina (late 2013) machine. However, the frequency of sudden reboots has increased substantially -- ie, I got one in 9 months under Mavericks and I'm getting one or two a week under Yosemite (which I only upgraded to in January). There is no way to generalize the conditions under which it happens -- at least not from a user application standpoint. It has occurred in the middle of browsing with Safari; just after clicking to open MS-Word-2011; and I forget the other time.
I know the crash dumps are sent to Apple, but is anyone else having this and/or has anyone heard of what Apple thinks about it?
Thanks,
Dave

Unfortunately, the article did not help. I've done all the troubleshooting steps in it several times and Yosemite is unstable on this machine, I do have several repeating error messages in the console that others have reported in other threads. I think these are symptoms rather than the direct cause. It's odd that the 2008 Mac Pro runs smoothly but the 2010 Westmere machine is very unstable.
I did, in fact downgrade to Mavericks and the system is now running beautifully, so I do not think its hardware related.
May give Yosemite another go at 10.0.3, but ive spent too much time troubleshooting to continue for now,

System restart automatically under Yosemite

Upgraded to Yosemite last week and the strangest thing happened-- the Mac restarted by itself. I was in other room and heard the restart sound and check on computer to find it automatically restarting. Is there a setting that allows or disables this? Is this something new to Yosemite?
I've been using Macs for 30 years and don't ever recall this happening before.
Thank you.
Tom

I was having unexpected system restarts in Yosemite on an Early 2011 15" MBP. I read that disabling file vault (which was enabled when I upgraded to Yosemite) might help, so I disabled it. Since then, I've not had a reoccurance of the restarting/logging out problem. I hope this might help you!

Any X1900 users have spontaneous reboots?

All:
I do realize that this may not be directly related to Motion, but it could be related to the graphics card, and this is the largest group that I can think of that would have X1900's.
I've, in the past, experienced a hard reboot during Motion renders when the X1900 intake was dirty. It seems that throwing a kernel panic is pretty normal if the X1900 doesn't have clean airflow. So, I clean the intake ever few months or if it gets loud.
Recently I've had my system (Mac Pro) reboot spontaneously during normal non-motion tasks like editing in FCP, watching Flash videos in Safari, and lately not doing anything at all (not even touching the system).
I'm curious if anyone has heard anything about this type of behavior based on the X1900. I've searched the webs and it looks like there are folks that have experienced these spontaneous reboots on Mac Pros but there is no apparent commonality. I'm currently cleaning my os drive (as it came back with errors), and have reset the SMC, but I realize this could also be a PSU issue, or even bad memory...
The reason I'm locked in on the GPU is that I know it has, and can bring my system down.
Just a shot in the dark in case anyone here had read or heard about this type of behavior.
Thanks.

Frustrating day but here's something worth reading in regards to GPU's, overheating, and geniuses:
My system spontaneously rebooted about 6 times today while doing all sorts of different things. FCP, Motion, simple web video surfing, and scrolling through a Safari window.
I called the Apple store here in Austin and they said they had the ATI 4870 in stock, but I'd have to bring my tower in because they have to install it. They can't support it if they don't install it. F-it, so I took it in to resolve the issue.
I went to the genius bar and the guy tried to recreate the reboots, albeit unsuccessfully. I think this is because there wasn't enough time to heat the thing up again, and we had a small monitor plugged into it.... and he opened up the side which certainly kept it from overheating. Dhrr. He ran a full system diagnostic and it came back clean. I explained my reasoning, that the X1900 had rebooted my system before, when it overheated. It seemed to be doing that now but without the dust buildup. Maybe old, or something... (or simple HEAT : meaning that heat seems to be the culprit for these reboots from the X1900 whether preceded by fan noise or not).
Then he informed me that the like for like replacement in my 2007 mac pro (no longer covered under any sort of warranty or applecare) was the nvidia 8800, about $600 bucks. I told him I wanted the 4870 that everyone says works in the 2007 Mac Pro, though it's not "supported," for $349. He looked at me funny, went and talked to his manager, then came back and said they wouldn't sell it to me since it wasn't supported on a mac pro 2007. Mind you the 8800 is twice as much, and they didn't even have it in stock.
Then he said they could keep it for 24 hours and try to recreate the problem, for 80 bucks. That way we could figure out if it was the graphics card. After I explained to him that I've scoured these discussion groups for the right solution for what I'm doing: MOTION, and that I'd gotten feedback that the 4870 seemed to be the right solution at the right cost, he told me I could go to frye's or newegg and buy one.
Long story short, it wasn't the best experience. But I did come home and try one more thing. I opted to download SMCfanControl 2.2.2 to actually speed up my internal fans. Basically I doubled the speed from a minimum of 500 rpm to around 1000, resting speed. Still a quiet speed this brought the temperature of my case down about 50 degrees, to an operating temp of about 100F. Before that it was running over 150F. It's been running solid for a WHILE now (fingers crossed). I pushed it with all sorts of stuff and it hasn't rebooted yet.
So, I think a few things are worth asking.
1: Did the System Management Control (SMC) change recently in a system update? I'm wondering if it's not picking up on the x1900's effect on the running temperature and letting it overheat my system.
2: Why can't they staff the the genius bar with geniuses.
3: Germany or the Netherlands?

PM8M3-V H spontaneously reboots

Hello,
I'm having problems with the following:
Motherboard: PM8M3-V H (3x PCI slots) - cannot find H/W version or serial number
BIOS: W7211VMS V3.1 060906 18:12:27
CPU: Pentium D 945 SL9QQ 3.4ghz
RAM: 2gb, 2x1gb PC2700 (DDR333), CL=2.5, 2.5V
(Crucial CT12864Z335.16TFY) (Micron Tech. 16VDDT12864AY335F2)
PSU: Trust PowerMaster 14888, 570W
+3.3V 32A, 360W
+5V 30A, 360W
+12V1 16A, 192W
+12V2 16A, 192W
-12V 1.0A, 12W
VGA: Onboard
The PC randomly and spontaneously reboots under moderate CPU load, such as running a SpyBot S&R scan. This occurs when running Windows XP and also in Windows XP PE booted from Hirens Boot CD v15.2.
Note: This is not a Blue Screen of Death followed by a reboot, it just reboots without warning.
Memory errors are sometimes found when running Memtest86 v4.20, but other times it can run four or more complete passes without any errors.
While trying to locate the problem, I have replaced:
* The CPU (Was a Celeron 3ghz CPU)
* The current RAM is from a know working system, in total I've to installed 3 different sets of RAM, also tried running with a single DIMM
* The hard disk (Used to be IDE, now its SATA)
* The onboard graphic card with a generic GeForce2 MX64 AGP card
* The PSU with 400W one.
I've tried to systematically adjust some of the DRAM settings, such as the speed and CAS Latency with no improvement.
I've also tried booting, directly after clearing the CMOS (Default settings), and with the 'Optimised' settings without success.
So far I've spent about 4 days trying to solve this issue. I'm about ready to throw out the mobo.
Thanks, Sean

Cheap PSU = Badly designed + poor quality components used from the cheapest manufacturer + a low life expectancy under any load as it will deteriorate quickly = within a 3 month period of use its dropped by 25% on all its rails and it starts to have very violent voltage ripple that causes damage and very unstable operation
to avoid problems like this GET A QUALITY UNIT like i already suggested (Corsair and Seasonic are amongst the best PSU's out there) as the ones you have are very cheap units from what looks like mass manufactured PC's that they make to just barely power the components for its expected life plus 6-12months and no more (maybe got a 1-3 years warranty and they expect it to be useless and broken down within a few months after its ran out as they do that to make sure you have to buy another one!) so don't use ones you pulled out old PC's from manufacturers unless its got a OCZ, Coolermaster, Corsair or Seasonic PSU as the ones they use are useless Generic ones that are glorified paperweights!
Please stop testing cheap and nasty PSU's as its not going to be of any help thank you!

Spontaneous Intel iMac Reboot under Leopard

I have three upgraded machines running under Leopard, two MacBooks and one Intel iMac. On only the Intel iMac I am experienced what can best be described as spontaneous reboots. Suddenly while working (web browsing with Safari) the screen will blank, no sound and reboot to the login screen.
Has happened twice in the last two days ... anyone else seeing this problem? Solution?

Same sort of problem here. We use the machine primarily for viewing TV in the kitchen with eyeTV. There is no clear pattern to the reboots. This log shows the timestamps of recent reboots.

Since 11/29 all other apps but eyeTV have been turned and kept off. Two reboots since. We have eyeTV running on two other machines (iMac G5 and MacPro) with no problems so we do not believe the issue is that software. Will happily provide syslogs to Apple if they are interested.

CleanMyMac has probably damaged your OS. You could try uninstalling it but it probably won't help. You will need to erase your HD and start over. "Cleaning" software like this is unnecessary and often harmful on Macs and should not be installed.

How do I know if my apps will work under Yosemite?

Hey guys, I'm running Yosemite right now on a mid-2011 Mac Mini that was originally running Lion. I then installed Mavericks on top of Lion(I didn't try Mountain Lion) and then I installed Yosemite on top of Mavericks. I'm planning on erasing the 500GB HDD and installing a fresh copy of Yosemite and then restore my apps and system preferences via an external Time Machine USB HDD I've been using for 2 years.
I'm having a spinning beachball issue that renders my Mac Mini unusable for a few minutes at a time and this is why I want to do a clean install of OSX.
So far my apps have been running great under Yosemite, BUT I'm worried that my apps are running great ONLY because I was running Lion and Mavericks before so the apps I'm running now are only working because the apps were installed onto the Lion and Mavericks 'layers'??? I haven't needed to re-install any apps since installing Yosemite.
How can I check that my apps will run under Yosemite?
Please help!

NewbMacUser wrote:
From what he said here: "Because, after you run the Upgrade, it is running Yosemite and not Lion or Mavericks."
How does that translate into this
So whatever apps I'm running at the moment on Yosemite will definitely work when I wipe the Mac's HDD?
You need to slow down and read what is being written

Links in Firefox and elsewhere malfunction under Yosemite

On my year old MacBook Pro all web links in Firefox and elsewhere malfunction under Yosemite. They open a new tab and appear to connect to incorrect web addresses where no content is displayed; that is, if pressing the link will generate any action at all. At present if a link appears as an address one could, of course, labouriously go old school: the addy can be copied, a new tab opened, the address pasted in, then hit return, and wait. If the link appears as a topic or subject in proxy for the address, i.e. no visible web address, the copy/cut/paste method will not work, therefore, the additional information sought at the link is lost to the viewer. Remedy? Thanks.

Seduc-
Thanks for the suggestion. I interpreted that you meant a new user for the OS X 10.10 (the MacBook Pro), so I went to preferences and created a new user in "Users & Groups." The system automatically established that new user as my iCloud persona, including my indelible e-mail address [email protected]. It's not what I would have established had I known what would happen, but it exists, so that's Reality. So, moving forward, the new user approach was not a successful resolve for the the inability to click links, and, thereby, be taken to the 'Link" represented site. I appreciate your efforts in trying to help me resolve this annoying glitch in the new Yosemite OS. Be well, C.A.R.Alfa

Kernel-Power Event ID 41: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Hello, Currently we are seeing this issue with a couple of our Lenovo T420s laptops with a Solid State Drive. ruffly about 10 or so. The Reboots happen randomly and do not create a dump file. We have contacted Lenovo and they are
not sure why its happening. Since this Crash I set it for Minidump this did not work my next steps will be to Disable Automatic restart on System Failure to see if it brings anything up. I am also looking at using Procmon to dump to a file as well.
If anyone has any other ideas please let me know.

Thank you.

We have tested and checked both the Bios and firmware of the SSD Drive's
Bios was up to date and no issue
Firmware was also up to date as well.
Users are still experiencing random Reboots.   I tried to capture the issue with Procmon but since the PC shutdown (Goes to a black screen no power at all even when turning the "Automatically
restart" off under Startup and Recovery) No dmp files as of yet. Unable to configure Procdump due to not knowing where the issue is and what is causing it to happen.
Going to replace one of the PC's with a New one with different hardware to see if this resolve the issue. If anyone has any idea's to be able to capture what maybe happening that would
be great.
Thank you.

IWork '09 won't update under Yosemite

I just updated my Mac Pro from Mountain Lion to Yosemite. I expected to see the new, Yosemite versions of Pages, Keynote and Numbers appear in the Mac App store under Yosemite, but instead, I see an "Open" button, not a "Download" button, and when I press it, the old, iWork '09 versions open. Similarly, when I search for "Pages" in the "Featured" page, I get an "Open" button, not a "Download" or even a "Buy" button.
How can I get the new versions?

Welcome to Apple Discussions Craig
Glad to see you searched & tried most of the things I've suggested to others. I have only seen a couple of users (you being one of them) for whom updating didn't fix the problem. Most of the people complained of having problems opening or saving Office files.
Have you tried opening the apps in another user account? This could narrow down the issue to your user account or a system-wide problem. If they do work in another user account, go to HD > Users > (your account) > Library > Preferences & delete the com.apple.iwork.pages.plist & then try starting Pages again. Repeat with the Numbers & Keynote plists.
System-wide issues could be a corrupt or duplicate font. Use Font Book to validate fonts & check for duplicates. Corrupt caches can also be a problem. You can restart in Safe Mode (hold down the shift key until you see the gray Apple screen) & then restart normally. This will clear a number of caches. Using a utility like OnyX (unfortunately not yet for Snow Leopard) to clean caches, logs, etc. can help.

Spontaneous reboots with BC 2.1

I successfully installed the Bootcamp 2.1 update late last night. As soon as I was done I booted back into Mac OS. This morning I've had three spontaneous reboots while in Windows XP. When booted back into Windows, Windows gives me that familiar serious error dialog box asking if I want to send a report to Microsoft. The reboots have all happened within about 5-10 minutes of startup and while doing different things each time. Haven't figured out a pattern yet.
Anyone else experiencing this? I've been running this setup for about two months now with no prior problems.
Thanks,
Jan
2.8GHz 24" iMac, 10.5.2, Windows XP SP2.

Please also see my other post which has got a lot of views, but no answers. I'll post this also to there. So I backed up my boot camp partition using Winclone and then opened up the MacBook Pro with Windows XP as the operating system. I turned off Norton Antivirus (I thought the more basic system would have less potential interactions with other systems) and downloaded bootcamp 2.1 again. Installed it and then restarted and then turned Norton back on (Norton AV has actually been a pretty stable version from my recent experience). My external keyboard is now connected and so far so good-- the computer has not been giving me the BSOD every 20-30 minutes. I remembered from long ago-- on the mac side-- I was always told to turn off virus software before installing any new software-- maybe that's what it needed? I will continue to update.
I never got a blue screen while downloading updates to windows. I've only gotten BSOD after that initial attempt to install Bootcamp 2.1 with antivirus software turned on. And I'm backed up so I can go back to version 2.0 if necessary.

Help! Spontaneous reboots on iMac w. 10.7.5

Hi,
So I have this mid-2007 iMac, purchased new, never any problems, swapped out the (still working) original hard-drive for a bigger, faster one last year. Here's the hardware overview:
   Model Name:    iMac
Model Identifier:    iMac7,1
Processor Name:    Intel Core 2 Duo
Processor Speed:    2.4 GHz
Number of Processors:    1
Total Number of Cores:    2
L2 Cache:    4 MB
Memory:    4 GB
Bus Speed:    800 MHz
Boot ROM Version:    IM71.007A.B03
SMC Version (system):    1.20f4
Serial Number (system):    W87****X86
The system started out on Leopard, I upgraded to Snow Leopard and Lion as those came out, with all incremental OS updates regularly downloaded and installed.
Last night, I let it install 10.7.5. Since this morning, thus far I have experienced 3 completely spontaneous reboots of the system. Good thing I save my work every few minutes ;-).
The kernel boot log helpfully reports that "Previous Shutdown Cause: 0" - which I've looked up to indicate a power failure; however, I'm on a stable circuit with surge protection, and there are no signs of power issues with the other devices on this circuit (desklight, printer, powered speaker). The log also shows these entries for SMC:
Sep 26 19:20:19 localhost kernel[0]: SMC::smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
Sep 26 19:20:19 localhost kernel[0]: SMC::smcReadKeyAction ERROR $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
Sep 26 19:20:19 localhost kernel[0]: SMC::smcInitHelper ERROR: MMIO regMap == NULL - fall back to old SMC mode
Which I assume are due to the fact that after the latest self-reboot, I reset SMC according to Apple support guidelines. I have also followed the guidelines for resetting PRAM/NVRAM. Yet the problem persists.
Has my iMac's power unit spontaneously decided to take a dump at exactly the same time I installed this latest OS update? What else can I do to diagnose and above all fix the issue? Maybe roll back to LKGC? Any ideas appreciated!
On a sidenote, I am also seeing the "indexing not working" issue reported by other 10.7.5 users.
Thanks, -oliver

Update from OP: I was close to swapping out the power unit in this iMac, but decided to first try an upgrade to Mountain Lion.
Since the update, five days ago, the system has been up and running and remains stable. The persistent spontaneous reboots due to "Shutdown Cause: 0" have no longer occurred. This would seem to indicate that my power unit is indeed a-ok, and that the shutdowns were being cause by an incompatibility between the hardware in this iMac and the 10.7.5 upgrade which was previously installed...

LaunchD Task Scheduler would Launch Automator Apps under Maverick but will not under Yosemite. Why Not?
I have tried going under System Preferences-Security&Privacy-Privacy and adding my Automator generated .app but that does not work.
Any suggestions?

Better check the site of the maker of that application for further information:

Server Spontaneously Rebooting

We are running OCS 9r2 on RH EL 2.1. Sometimes when users are in an active conference, the server just spontaneously reboots.
I've seen the processes running when the server reboots, there is virtually no load at the time. The CPUs are almost completely idle.
We cleared out some log files in case it was somehow related. I've also checked these files for anything helpful.
Anyone have an idea?

No, unfortunately there is nothing in the messages file. Apparently, there is nothing being written before the server bounces. There might be if it were a Solaris machine.
I am trying to find out if the users are doing something specific when the server reboots. To date, they haven't indicated they are doing anything out of the ordinary.
I have checked all of the logs under $OH/opmn/logs and $OH/imeeting/logs, there is really nothing I can find to explain this.
