Mac pro shuts down suddenly power light still on wont start

just hadd new logic board as apple thought it was that causing sudden shut downs

Well, why not put your hardware profile for all to see, and whether Apple OEM or upgraded graphic card; whether Apple Hardware Test has any useful information. Even running Memtest on your RAM.
Monitor the internal temps of everything you can (video we are expected to fly blind as there is no useful GPU-Z utility).
If anything, boosting the default fan speeds by 300 rpm won't hurt, and commonly done.
That model had a EFI firmware update to deal with trouble crashing on wake from sleep and inrush current, fwiw even though you aren't sleeping the system.
An SMC Reset (the longer the better) and zap pram/nvram are probably one line of troubleshooting. But I wouldn't wait to repair your drives with Disk Warrior from an emergency backup/clone boot drive as any such freeze can only just lead to more problems than originally.

My MAC Pro shuts down when the battery still have 50 minutes life.

My MAC Pro shuts down when the battery still has 52 minutes life without any warning. Does anyone have this problem? BTW, it is less than one year old.

You must have a MacBookPro, right? MacPro's are big desktop models.

Mac Pro Shuts down

Hi.
My Mac pro shuts down unexpectedly after about three days. And I don't know why. It never happens when I'm working with the computer. In pref it is set to never shut down or rest and to turn on automatically after power failure. But this dosen't seem to work either.
I made a dump from system log or what it is called in english. Maybe someone smart can figure out what seems to be the problem by reading the things happening before the shut down?
I have a FTP server on the mac so I would like it to be up and running all the time.
OS is 10.9.5
regards

new log if anyone have any ideas what seems to be the problem.

Mac Pro shuts down after setting up RAID (HELP!)

So, I recently purchased a rev 1 Mac Pro and decided to setup a RAID using 4 750gb WD drives. I am not using a RAID card, simply using Disk Utility.
I first combined drives in bays 1 and 2 (striped) and then combined drives in bays 3 and 4 (striped) to give me essentially two 1.5tb drives.
I then created a mirrored RAID using the two striped raids so that I would have the speed of a striped RAID with the safety of a mirrored RAID.
Once I did this, it showed up as one hard disk on my desktop (I was booting with an external). I then cloned my external drive to the new RAID disk on the desktop, and did so successfully.
However, now when I try to boot from the RAID, it chimes, the Apple appears, and then the Mac Pro shuts down. I tried holding down option and all 4 drives appear. I tried booting from a different drive, and the same thing happens. I should also note that the firmware bar flashes on the screen before shutting down (looks like a really long pill).
Any ideas? Does it sound like I did something wrong? I hate to start from scratch, as it takes all night to clone my external drive to the Mac Pro. Thanks for any help.

Hello, Hatter. Thanks so much for the information. I went with the information from the Macworld article (I believe) "RAIDing the Mac Pro" and according to it this setup was supposedly a great idea. But, yes, it's not working out so perhaps not in this case.
So, I have four brand new 750gb Caviar Black drives installed. If I understand you correctly, I should stripe 3 disks together, then use a 4th as backup (using Time Machine?). So, if I use the drives I have, I'll have a striped configuration that gives me 2.25TB of space, and a 750gb hard drive for backup. That technically would work for now, as I have about 660gb of data on the system (although in the future I'd need to swap out that 4th drive for a 2TB.
So, if that is what you're suggesting, would you mind telling me exactly how I do that? I think I understand, but just want to make sure as this is my first Mac Pro and first time setting up a RAID. Thank you so much for your response.
p.s.: I'm guessing I'll need to do a fresh start and clone my external drive all over again, correct?

My brand new Mac Pro shuts down for no reason

My two week old Mac Pro shut downs for no pparent reason. Using the wireless, not plug in to an outlet but battery fully charged. Both times happen within 15hrs. apart.

Take it back to Apple and ask them to fix it.

My Mac Pro Shuts down during sleep

Well I have a variation on what others are experiencing with their machine.
1- I put the mac to sleep. Or it goes to sleep when i's supposed to.
2- I let it sleep at least a few minutes…
3- when I press the space bar, the following happens:
- the mac responds immediately (see below)
- the fans kick in just as when you start it from shut down with power button
- the startup screen appears and everything after this point is the same as a cold boot.
I'm puzzled, but this is more an info message than a call for help.
My setup:
2.8 GHz 8 core Jan 2008 mac pro.
4x2 GB RAM from OWC (667 Mhz)
2x1 GB RAM (factory) reseated to follow the RAM arrangements guideline.
8800 GT video Card.
4x 750 GB Seagate drives. formatted as two RAID 0 pairs. One of the two holds the OS and apps.
The only other thing present is the OWC/Newertech S-ATA adapter that essentially brings the 2 unused SATA ports to the back of the compouter. Nothing is plugged to this for now.
Software:
OS 10.5.2 ans all updates applied.
for the moment the only non-apple app installed is the temperature monitor suite.
Hope this tells something to others. Will send this info as "feedback" to apple.

Ok so my g5 died...still complaining. Should have had apple replace it while still under apple care.
Had to buy an intel mac which has limited compatibility but is fast, durable.... i doubt it. I was sold on the g4s before i switched to apple. Never owned one bought a g5 to switch from pc for audio recording. Durability was my goal, didn't think i would ever need mac pro.
Mac pro reboots after it has been asleep. This is not a ram error. It is a design flaw. Their are many things that cause sleep issues which seem to be very complicated. This problem is sold with your mac.
The first thing i did before i even opened the box was read apple discussions on this issue and other bug reports. There are lots of reports on this particular issue as i was familiar with it the first time it happened to me which was maybe the second time i put the computer to sleep. To be honest why there hasn't been an immediate bug fix is disheartening. All i got to say is typical. I think i will be having some very stern words with apple tomorrow. Over all dissappointment in all departments regarding apple- durability, compatibility, backwards compatibility, customer support, and their inability to stand behind their flagship machines. I guess they're just a second rate circuit city brand. This is not only a rant.

My Mac Pro shuts down prematurely. Seems the battery drains almost instantaneously, once it hits about 50% or less.

My Mac Book Pro shuts down prematurely, seemingly doing a rapid battery drain when it reaches < 45%. I can only work, while on battery for approximately 15 minutes even when starting out fully charged. Although, a full charge now only reached 95% - 97%. Can't recall if it ever reached 100. Looks like the battery has about 240 cycles on it. I thought at first it was over heating, but now not so sure. Heat may be normal levels. Does this mean it is time for a new battery?

Apple menu > About this Mac > more information
scroll down to Power and click
look for Battery Health Information, Cycle count and condition.

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

I go to click my mouse of keyboard and nothing happens. I click the power button the back lights up and turns on as if it were off, what gives? This is brand new 64gb ram, 12 core, didn't even do a migration so it's all new stuff on here.

Hello Chief Sneed,
It sounds like your computer is going to sleep but when you later go to wake it up it will not turn on unless you press the power button and it looks to have shutdown at some point. I recommend checking to see if the computer is scheduled to shutdown at a certain time with the following article:
OS X Mavericks: Schedule your Mac to shut down or go to sleep automatically
http://support.apple.com/kb/PH13914
Schedule your Mac to turn on, turn off, go to sleep, or wake from sleep at specified times. You might do this if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.
Choose Apple menu > System Preferences, then click Energy Saver.
Click Schedule, then select the options you want to use.
To schedule a startup or wake time for your Mac, select the “Start up or wake” checkbox. Choose a day or group of days from the pop-up menu, then enter a time.
To schedule a shutdown, sleep, or restart time for your Mac, select the bottom checkbox and choose the appropriate option from the pop-up menu. Choose a day or group of days from the pop-up menu, then enter a time.
Thank you for using Apple Support Communities.
Take care,
Sterling

Why mac pro shuts down when idle, even when charging ipad?

why mac pro shuts off when idle, even while charging ipad?

Thanks for replying. I have a macbook Pro. In my energy saver, I ticked the following: put hard disk to sleep when possible, wake for network access and automatically reduce brightness before display goes to sleep. My boyfriend has the same settings but I can charge my ipad with no interruption on his macbook Pro and it doesn't shuts off when idle. Thanks for your help

Mac Pro shuts down immediately

When I start my Mac Pro by pressing the power button the fans kick in and it sound like it's about to start for a second, then it immediately switches itself off. This happens time after time every morning. After unplugging everything from the back and plugging it all back in again I can often get it to start up, eventually, then it's usually fine for the rest of the day. Next morning, same problem. It's very disconcerting.
This problem has only started to happen fairly recently and I'm pretty sure the warranty has expired. Can anybody help?

Hi Dale. The other things were zapping the PRAM and also running Onyx to clear a few things out (just as a voodoo measure I'm sure).
I had the problem again this morning and unplugging peripherals (one at a time) didn't help. I'm suspicious (probably superstitiously) though that it may have something to do with the Apple display screen as it connects to the Mac via USB as a way to turn itself on and off. A few months ago I adjusted the angle of the screen and the screen spontaneously turned itself off, I presumed it wasn't plugged in properly at the time and I have no idea if this is connected to the current problems I'm having. I'm also suspicious that there may be a power issue due to how many peripherals are plugged into the same extension as the Mac, so I'm going to try limiting that too.
This morning however I have opened the Mac up and found it to be incredibly dusty inside. I'm off to buy some canned air and will try clearing the dust out. I'll also move the Mac to a less dusty and more easily serviceable position.
Thanks for your input guys and I'll let you know how I get on.

Mac Pro shuts down but light stays on

I was online and suddenly the screen went black and gave me the message that it wasn't receiving a signal. But the little blue light on the Mac Pro was still on. I held down the power button to restart and seems to be working fine now. This is the second time it happened.
Any ideas?

Power Supply Temperatures Running Hot! Mac Pro shuts down.

Hello,
First I will give machine/hardware specs of interest:
2 x 3 GHz Quad-Core Intel Xeon (pre 2009)
8 GB 800 MHz DDR2 FB-DIMM
NVIDIA Quadro FX 5600 (running 2 displays)
Apple RAID Card/Controller
SMC Version: 1.25f4
*venting dimensions around computer: top=18", left side=3", right side=3" and back=18".
Software of interest currently running:
OS X 10.5.8
iStat Menu
SMC Fan Control
My machine has been shutting down spontaneously and I suspect either CPU or power supply overheating. In the 5 instances this has occurred, the room was very warm (AC was not on) and I was running HandBrake with CPU at full and an iStat reading of 145 F. Ambient was 77 F and I was not reading power supply temps at the time. I figured for sure this must be a CPU overheating issue. However, just a few hours ago I had another shutdown. The room was warm again but I was not running Handbrake, but StarCraft II. I have played a lot of Starcraft II with no problems until tonight.
I decided, this time, to check the temps on my power supplies. Power supply 1 = 147 F, and #2 is at 178 F. After many hours of searching forums I have concluded that these are crazy hot temps! I immediately installed SMC Fan Control to attempt to increase the fan speeds. I was successful in increasing all fans except the power supply (stuck at 599rpm). I have now turned the AC on in the house and the Ambient is down to 70, PS #1 145 and PS #2 169. All of these temps are a result of and idle machine running a browser.
The following may or may not be an issue, however, leave no stone unturned. I currently have 12 external devices running on USB. 4 WD passport drives, 1 DVD writer, 5 WD powered drives plus the keyboard and mouse. Also, the Mac Pro is plugged into a small UPS.
In all my forum searches, I just can't seem to answer some basic questions:
1. Can an overheated power supply shut the system down?
2. What are optimal (normal) running temps for Mac Pro's? (everyone seems to have opinions, but there doesn't appear to be a technical specification anywhere).
3. I thought the fans, especially CPU fans, were supposed to kick in when the heat rises. Why are mine staying at minimal rpm's?
Finally, does it look like I need new power supplies? Fans?
This machine was put into service in March of 2008 and has done very intensive rendering for the film industry...long nights...rendering for days sometimes. It has been retired for over a year now and is used at a lesser degree.
Thanks for reading this long post! I appreciate any input you can provide!
Other iStat reading of interest:
Power Supply 1 voltage = 12.28 V
Power Supply 1 current = 26.44 A
Power Supply 1 power = 316.75 W

Also, the Mac Pro is plugged into a small UPS.
Put your peripherals on that.
Don't share the same circuit for A/C as the Mac Pro, and put the Mac on 1300VA UPS at least.
As for all those external drives.... I'd consolidate into a good SATA case or two.
And yes in summer run with 3 of the fans up around 900 rpm.

Early 2008 Mac Pro shut downs during start up and restarts to full power fans, Help!

I have searched through all the forums all day and can't find anyone with the exact same problem.
It doesn't matter if I'm booting up to Windows 7 (boot camp) or OS X.The computer will start booting... and anywhere between the "apple tone" and the login screen it will shut off all the displays, shut down the HDDs, shut down the GPU fan and spool up the main fans to 100%.
I have reset the SMC and PRAM. All the diagnostic LEDs are displaying correctly (no overheating, GPU lights on). No RAM LEDs are lit up. The white LED on the front remains lit constantly. It won't stay running long enough for me to run the diagnostic disk.
I first thought it was a GPU (Nvidia 8800) issue, but after removing it and booting up with no video card... the outcome was the same. I'm leaning towards a PSU failure, but I haven't found anything to back up my theory. I'm hoping it's not a logic board failure... I would think there would be LEDs lighting up or something more definitive.
Can anyone help?!?!

There are multiple threads and reports of issues with Icy Dock - there is one on Amazon that lines up properly.
The drive sled length of 2009-2012 Mac Pro are longer. Maybe OWC needs to be clearer.
You'e right half-way and maybe some corrupt plist or interferring process you have, or even another hardware item or cable - external - even printer drivers or something that refuses or does not like sleep. Controller card?
All around I'd have to vote for Samsung 830 model. Then Intel 520. Crucial is out with x4 now (Or is it "V"?)
SSD firmware continues to be trouble. Even May-June the SandForce firmware had major issue and reason to hold off any using theirs. Reason to see if yours needed to be updated. Someone last week with m4 found they had old firmware and needed to update it.

Mac Book Pro shuts down suddenly

I have been using my mac book pro without problems. All of a sudden I cant move the mouse anymore and the computer shuts down. It will restart itself with a message that reads something like your computer is restarting in 15 seconds or so but click anywhere to get in. Its just weird. I dont see any problems other than it does say I need to service battery. So is this the intial problem or is it something else? What can I do? Am I damaging my computer if I need a new battery? Help please....!

first if you are getting message that your battery needs service, you want to get it looked at either by going to apple store or service provider.
try doing an SMC reset, the following article tells how:
http://support.apple.com/kb/HT3964
after this reset restart the computer and see if it works normally if it doesn't see below.
second regarding the restart of your computer, it could be a kernel panic. the following article tells how to troubleshoot this issue:
http://support.apple.com/kb/TS3742
if after following this article the mac continues to restart try running the apple hardware test to see if there is a hardware issue:
http://support.apple.com/kb/HT1509
if none of the above steps resolve your issue i would take to apple store or service provider to have it serviced.
