I cannot say it is fully gone (every time I post something else comes up) but after I switched off automatic time machine (backing up when it occurs to me, manually) the reboot is certainly much less frequent. I do not think I had any in the last week. I also have upgraded memory but I do not think that would be an issue. Apple replaced my HDD at one point, claiming that failed, it may have had a bad sector but am still skeptical about the analysis. Anyway, the new one made no difference it that sense but it gave me an opportunity to check the HDD wires (my MBP is '09 but is running fine). So try switching off backup. Something wants to start again when you reboot and that fails, so I would also inactivate (for now) all login items.

Thanks!
Trouble is that I have just done a fresh OS install with no external drives attached and no login items because the Mini will keep rebooting even before the new system setup completes!

I see : that is actually close to what I saw with Yosemite. That is when Apple replaced my HDD (I still think there is some other thing than that bad unrecoverable sector). the Startup line stalled half-way and rebooted after a while. When I went to recovery mode (startup + R) it kept showing Maverick. I also did a hardware test (startup + D, though I needed another method) to look for errors, I myself saw nothing but Apple did. Anyway, did you try disk repair then reinstall? When I did that it finally flipped over to Yosemite and finish booting up (I do not have this issue with the EC update).

Yes, I tried Disk Repair several times but it never reported any problems. Last night I installed yet another internal drive (I've become an expert poking inside the Mini!) that I used as temporary storage at work. I did another clean install with exactly the same results: the Mini would start rebooting halfway through the setup process. Looks like something in the motherboard has gone bad and it's time for a new computer.

I concur, might not be a mac :) we have two at home but I need one that works, and I do get a proper support response, not the claim I do not know how to use it... ;)

Upgraded to El Capitan this morning without issue. No problems until my mac went to sleep. When trying to wake, it restarted around 7 times. Will work fine for most things now, including photoshop work. However any attempt to enter time machine or back up using time machine automatically shuts it down.

Never had this issue until this mornings update. Any thoughts? I do like the new OS, and would love to not have to take it back to Yosemite. But I do need the system to be stable and to be able to back up.

Thanks in advance.
[doublepost=1452513024][/doublepost]Try going into System Preferences/Security & Privacy/General - You'll see that you have ticked "Require Password x minutes after sleep or screen saver begins" ....That's OK and is what you need.

However, if you go to ADVANCED on the same page, you'll see that you probably also have ticked "Log out after x minutes of inactivity"

If you uptick this, it should solve your problem...

I do not have those settings checked. My MBP is restarting constantly after this El Capitan update and very frustrating! I personally think this OS has flaw and should have never been offered to the machine that is not compatible with!
Apple! FIX THE DAMN OS!!!

I found some articles that may help. I'm going to play with my power settings. For me, when my computer is plugged in, after about 10-15 minutes, I come back anomy computer is restarting itself. I enter my password and a little loading bar comes up, then everything takes a moment but eventually all my apps and windows are open. I was reading some of the thread when I saw someone posted about the settings, so I went into the energy saver ones and found the "Enable Power Nap" option. It's checked for when it's plugged in and not when it just runs on the battery. I'm turning it off and I will test it. I'll let you all know how it works.

Hi. I am posting in this forum because I have a user with this exact problem on a late 2015 27" iMac. It's running El Kapitan. The console has not been much help, as it only reports the last restart, and we can only really confirm that it went down by checking uptime.

We verified that PowerNap is off, and it has been off. Has anyone found any other cause of this problem?

[doublepost=1483346317][/doublepost]Sorry about the null post - new to this. I just bought the shiny new flagship MacBook Pro and was pretty disappointed to experience this problem. I think I initiated it by trying to copy very large groups of files from one external drive to another and/or deleting terabytes from trash. Other users have described temporary problems with doing this.

Anywho, I have the fix. I found (and followed) this advice and problem solved:

Hello guys!

I have (had?) the same problem than you.


• Apple MacBook Pro (3.1) (15") (2007)
(CPU = Intel Core 2 Duo 2.4 GHz)
(SD-RAM = DDR2 667 MHz, 4 Go)
(Graph Card = nVidia GeForce 8600M GT, 256 Mo)


• For several years,
my MacBook Pro was running quite happily with Mac OS 10.6 (Snow Leopard).

When I was abusing on resource-hungry apps launched together,
it simply ran slower and with more fan noises, but NEVER AUTO-SHUTDOWN.


• After I upgraded (not sure about this one...) to Mac OS 10.8 (Mountain Lion),
I started to experience unexpected sudden AUTO-SHUTDOWNS,
but only on a weekly basis (albeit using my computer everyday).

During last summer 2016, I noticed that
the EXTERNAL/AMBIENT TEMPERATURE makes the problem worse.

I use my laptop computer for musical purposes,
so, in the middle of the month of August, I bring it on stage for a live concert.

While not exposed directly to the sun
the poor MacBook Pro had to suffer a full-length afternoon of hot weather.
I tried to make the experience easier for it
by installing 2 fans (a big one and a tiny one) just in front of it.
Nonetheless, in the middle of the show (and in the middle of a song!),
I experienced a sudden shutdown, and had to restart the whole thing.
Hopefully, the guitarist my dude saved the day by improvising an interlude! :p



• Afterwards,
I upgraded (neither sure about this one...) to Mac OS 10.11.6 (15G31) (El Capitan).

I was very disappointed about the new Graphical User Interface look (which is just plain ugly, I feel),
so I heavily customized it
(with XRevert + XtraFinder + Total Finder + cDock + OnyX + MenuMeters + you name it...)

But then, those sudden shutdowns began to happen more frequently (say, once a day.)
Very very disappointing and annoying!

In my quest to identify the apps that could be the cause of the problem,
I noticed several things:


(1)

Just before the (dreaded) black screen,
I have just a second of time (or so) to read the CPU Meters.

Verdict: contrary to what I supposed,
the shutdowns are not directly related to a high CPU usage

They may be indirectly related, however.


(2)

The shutdown often happens when
I'm listening to some audio files located on an external drive, using VLC or iTunes.

But it also happens when I use other apps, however.



(3)

Someone here talked about the System Preferences.

I also tried to tweak these settings.
In particular, I tried to set the Drive Shutdown Time to "never".

But this didn't prevent the unexpected sudden System Shutdowns.


(4)

Similarly,
deactivating the OS Configurators/Customizators
(XRevert + XtraFinder + Total Finder + cDock + OnyX + MenuMeters + you name it...)
doesn't cure the problem, so it's not their fault.


(5)

I wondered if this could had something to do with the InterNet.
Nope: when connected to the web or not, the same problem is still happening.



• This evening, the following happened :

I was running (Ableton) Live (a music app which is both CPU-hungry and RAM-hungry),
while at the same time I was looking for something on Internet, using (Google) Chrome.

As too often, a page for an On-Line Video Game automatically opened.
Normally, I immediately close that kind of unwanted tabs.
But this time, the game looked nice (for those who care, it's called Elvenar),
so I decided to try it a few minutes.
And then... Bam! Shutdown!

As usual, I was upset, but this event gave me the idea to test something.
As a first step to find the cause, I tried to REPRODUCE THE PROBLEM AT WILL.

I restarted the computer, and choose the option to
re-open all the apps that were opened before the auto-shutdown.
With exactly those same apps and web pages,
I experienced several auto-shutdowns in a row.

OK, these two kinds of apps (Music & Video Games) are both CPU-hungry & RAM-hungry,
but I'm pretty sure I would have been able to
do the same with Snow Leopard without any System Auto-Shutdown.



• Finally, I decided to really search for the CAUSE (and hopefully, a SOLUTION) to this problem.

That's how I ended on this forum.

Reading what you said you tried gave me an idea.

Since those AUTO-SHUTDOWNS
have something to do with the TEMPERATURE,
and since it is well known that Batteries produce HEAT,
I was wondering if the cause could be the BATTERY.

So I REMOVED THE BATTERY, went on AC Power alone,
LAUNCHED THE SAME APPS as before...
and EVERYTHING RUNS PERFECTLY !

I must admit that
the Battery of my MacBook Pro is almost (or definitively...) dead
(I plan to buy a new one very soon),
so I'm very curious to know what will happen if you remove YOURS.

Oh no, please! Don't tell me all of you run your laptop computer on a DEAD BATTERY... :v)

SOLVED. Yes, really...it works for at least 2 days in a row. Restarting on my 2010 mac started while there was still original OS. That is why I put new OS last year, but the problem did not dissapear. Reatarts killed HDD, then I put new SSD, also the latest OS. It was 3 days ago. At the beginning I used only Safari to install all neccessary progs (i was happy, machine did not restart for several hours)...firefox as well...and suddenly it started. Then I found this forum and someone already mentioned that Firefox my have cause the problem. Indeed, I uninstalled it and my mac is working fine for already 2 days with no restarts. Seems that Firefox was a killer.

My iMac isn't showing any evidence of a crash, but if I let it go to sleep, I'll come back to it and my sign-in looks like its the first of the day.

I never shut down or log off (nobody else uses this machine), so I'm really confused. I'm just glad I closed FCPx before bed last night.

Hey Mr Wilson, did you fix that problem?
The same happening here. Not a clue about what it could be.
Thanks.

First, my apologies for waking this sleeping thread.

Around Thanksgiving (US holiday) I upgraded my wife's MP 9,1 to OS X 10.11.6. It was very stable before hand but now reboots every day or two.

She has a none Apple keyboard (Razor with its own driver) and none Apple mouse (also Razor). Outside of that she has a TimeCapsule and a USB iPhone charging cable (and Apple Watch cable). All of these are connected via an older USB hub that is connected to A/C power. Also has a UPS connected via the same USB hub.

The Razor driver(s) has been updated and it did the reboot again Thursday at 4:14PM. I was on the phone with her when it happened.

Message #10 from above will be tried for most of the steps (not re-installing at this time) and am hoping for a good outcome.

Was wondering if anyone fully resolved the issue and if so if they found root cause for the issue.

Thanks,
