New Mac Pro shuts down when I put it to sleep?

I do have the same problem. It started right after I installed a new USB3 D-link hub on my mac.

It was actually a issue with my solid state drive. Apple has my comp and they said it might be more serious and they will contact me with more details. I hadn't heard back yet. I'll let you guys know what the final issue was

Same problem here.

SMC Update!? Are you kidding? That's why Macs cost $1500+

The answers of the experts: Check: "Schedule your Mac to shut down or go to sleep automatically".

What can I say.

Is there any way to make this the top comment? This box seems to be checked by default. took me weeks to figure this out.

Very late in the day, I think I may have stumbled on a solution. Thanks to whoever posted the suggestion to study the system log messages using the Console application. There I was able to see that

• My MacBook Pro (Retina Display 15") was put to sleep at about 19:11 when I closed its lid
• It woke up almost an hour later (this is unexpected, as I had not taken it out of my backpack)
• It hibernated exactly two hours after that; the trigger was:
  21/08/2015 22:12:06.000 kernel[0]: Wake reason: EC.SleepTimer (SleepTimer)

I conclude that the hibernate trigger was the auto-poweroff setting (see pmset -g in a terminal window), though I would have expected it to occur after four hours rather than two, given the default auto-poweroff setting of 14400.

More interesting is the message at the time the computer unexpectedly woke up:

21/08/2015 20:11:59.000 kernel[0]: Wake reason: RTC (Alarm)

I checked my energy saver settings again and found that "Enable Power Nap" was selected on in the battery power settings. I had not previously bothered to inquire what this entails. See How Power Nap works on your Mac - Apple Support for details. I think it may be waking up the notebook periodically to synchronize something, then not going back to sleep and eventually hibernating. Anyway, I see no reason to need the Power Nap feature while sleeping on battery power, so I have turned it off. Let's see if that resolves the problem.

It appears I'm not on my own here then.

I have a mid 2012 Mac pro. I've been running Ubuntu on it as a dual boot option for some time and never bene able to get it to sleep properly, I just assumed it was an ubuntu drivers issue but I've since started using Mac OSX on it with ubuntu in a VM instead and discovered that even with a completely fresh version of OSX on it it still wont sleep.

What happens for me is that when I put it to sleep it seems to take a about 30 seconds and then just switches off, a few seconds after that it turns it's self back on and boots up as if it had been previously completely shut down. No errors on boot up.

Extremely odd.

Did anybody ever actually get anything done by Apple to fix their Mac Pro? I see a few people talking about MacBook Pros but just to confirm, mine is the desktop Mac Pro.

Any suggestions?

Thanks in advance

No it is not what you installed. I have a 12 core trash can (with 32GB ram from apple) with the 700 VC. I had it out of the box and connected to a keyboard (USB) and a magic mouse and one monitor. Didn't install anything on it for the first 5 days as I was busy. It restarted itself every day! Changing the energy saver doesn't do a thing, neither does zapping PRAM, NVRAM, even starting in safe mode and running utilities for cleanup. It is an OS problem. My solution is simple:

OPEN PAGES, Make a new document and type few keys in BUT do NOT save it. Just leave it alone. It goes to sleep and screen saver for me and when I wake it up it has a message that Pages stopped logging out!! It is ridiculous but it is the only work around I have found.

The odd thing for me is I tell mine to go to sleep if I don't use it for a certain time period, I don't us the Mac Pro a great deal, I most use my laptop so I just want it to go to sleep when not in use.

When It goes to sleep it immediately turns completely off. The annoying bit is it's set to turn back on after ra power failure which then makes it power back up! I'm afraid it could be doing damage turning on and off so much.

For a machine that cost so much you'd expect better 😟

I've been going round and round for a couple days on this!

Finally found this thread, and your post.

I don't know how that got checked, because I would never choose that option!

Still testing...time has to pass! LOL! But, so far, so good.

I'll post back if it doesn't work! =( And, I'll go back to shedding some tears! 😢 and getting frustrated!

But, I am keeping my fingers crossed!

THANKS! kmpeters

I had this same issue and am pretty confident I found the solution

Preferences > Security > General > Unlock (bottom left with Admin pass) > Advanced (bottom right) > Uncheck Logoff

Also of course make sure you your energy saving settings for both battery and plugged in are not set to sleep the hard drive, etc...

Preferences > Energy

Hope this helps!

I've had this issue for about 2 years. Has apple or anyone ever found a solution?

I followed kmpeters post not too far back.

Basically, I made sure "Log out after ____ minutes inactivity" was UNCHECKED. I didn't even realize it was checked.

Start at the Apple Logo upper left, choose System Preferences, choose Security & Privacy. At that point you might have to type in an Admin password. Then choose "Advanced..." lower right corner. You'll see the Log out option at the top of the list. Uncheck and click OK. This worked for me.

You can check your Energy Saver settings in System Preferences, but no matter what I changed them to, the behavior continued until I unchecked that box. In Energy Saver, I still have the Put hard disks to sleep checked.

Good Luck!

I have a very similar problem for Months now. on a 2010 Mac Pro. I think ever since I install El Capitan

from this thread I will try:

• unchecking the Log Out issue in Privacy
• unchecking the Put HD to sleep when possible
• If these fail I will try editing that code to 999999

What different:

My situation is a Network machine at work. Sleeping a short period does nothing too, but over night I come in and the machine has been "attempting" to turn off.

What is interesting is that if a document is not saved, the machine doesn't shut down. It closes everything it can but once a file is prompted with a save command, the shutdown stops. (order of program shut down is random so sometimes whats still open the next day is different)

So if i come in in the morning:

• My network connection is lost, (sometimes even the shortcuts in the left Finder pain too (****** me off))
• Outlook and other programs are closed.
• Photoshop / Illustrator often stay open as I often have a file or two unsaved.

I am prompted with a Save command or a relink images... I can cancel all of this and the machine will not shut down.

I then have to reconnect to the network.

So a Bandaid solution for now for anything with this problem, I recommend opening a document, and NOT saving it.??

Yes, I almost just browsed over it to the next comment, and here I am 🙂

OMG, this did it...will monitor for a couple days.
