Intermittent Shutdown
Unlikely cause:  Optical drive(s), hard drive(s), fans, memory, processors, PCIe cards, speaker, 
AirPort card, Bluetooth card
Quick Check
SymptomsQuick Check
Intermittent Shutdown
• Computer intermittently shuts 
down, restarts, sleeps
• Fans run fast
• Slow computer performance 
prior to intermittent shutdown, 
restart, sleep
1. Confirm known good AC power source, and a 
known good power cord is fully inserted into the 
back of the computer
2.  Reset SMC
3. Power ON the computer
4.  After power ON, verify front panel power/sleep 
LED illuminated, and not flashing any error 
sequences indicating a memory failure.
5. Startup from known good compatible boot 
device with ‘Shift’ key to boot into safe mode.
6.  Check system.log in the Console to identify 
possible shutdown causes. If the computer won’t 
stay ON for long enough, place the customers’ 
hard drive into a known-good computer and 
retrieve the logs.
7. Confirm Energy Saver Settings, check for 
scheduled shutdown/startup/sleep times
8.  Run AHT/ASD for sensor/fan thermal tests. Reset 
SMC by unplugging the AC power cord for 15 
seconds. Reconnect the power cord ensuring 
the power button is not being pressed. After 5 
seconds press the power button and verify if the 
computer turns on.

1. Verify shutdown/restart/
sleep issue does not occur 
with a known good AC 
Mains power source. Rule out  
customer environment such 
as defective, uninterruptable 
power supplies. Rule out 
power generators which may 
produce noisy power, straining 
the computer’s internal power 
supply and causing issues. 
YesSuspect unstable AC Mains 
power source. Using an 
alternate AC Mains power 
source resolves issue. 
NoGo to step 2
2.  Remove all non critical internal 
and external peripherals, i.e. 
AirPort, Bluetooth, PCIe cards, 
external USB drives etc. Verify 
shutdown/restart/sleep issue 
does not occur
YesShutdown/restart/sleep issue 
does not occur when internal 
and external peripherals 
removed. Troubleshoot 
suspected peripherals.
NoGo to step 3
3. Verify if fans are running fast.YesGo to “Fast/Failed Fans” Flow
NoFans running at normal speed. 
Go to step 4.
4.  Reset SMC. Verify computer 
functions correctly and does 
not intermittently shutdown/
restart/sleep.
YesCorrupt SMC State causing 
power stability issues. 
Resetting SMC has resolved 
the issue.
NoGo to step 5
5. Attempt to boot from original 
or compatible install media, or 
from a known good external 
hard drive with compatible OS 
X installed.  
Verify computer stays ON 
without any intermittent 
shutdown/restart/sleep.
YesComputer power remains 
stable and does not 
intermittently shutdown/
restart/sleep. Clean install 
customer HD with compatible 
OS. Perform all Software 
Updates if required. 
NoGo to step 5  
						

							Mac Pro (Mid 2010) Symptom Charts — Intermittent Shutdown 47 2010-12-06
6. Disconnect all internal boot 
volumes. The computer should 
not discover any boot volumes 
and should start to the flashing 
“Folder?” Verify if the computer 
continues to intermittently 
shutdown/restart/sleep 
YesComputer continues to 
shutdown/restart/sleep.  Refer 
to Minimum Configuration 
Testing troubleshooting: 
Remove all modules and 
peripherals not critical 
to operation. Verify that 
computer functions correctly 
and does not shutdown/
reset/sleep unexpectedly. 
Then reinstall modules one 
at a time and restest until 
symptom returns. Verify that 
the last module added is not 
the cause by removing it 
again. 
NoRun Apple Service Diagnostic 
from an external USB drive. 
Suggest to also go to 
Minimum Configuration 
Testing if no errors are found.  
						

							Mac Pro (Mid 2010) Symptom Charts — Memory Issues/Kernel Panic and Freezes 48 2010-12-06
Memory Issues/Kernel Panic and Freezes
Unlikely cause:  Power supply, fans, enclosure
Quick Check
SymptomsQuick Check
Memory Issues/Kernel Panic and 
Freezes
• Computer has kernel panic 
or freezes on startup, when 
waking from sleep, or during 
normal operation
• Memory not recognized in 
System Profiler
• Fans run fast
1. Reseat all DIMMs. Refer to Memory Diagnostic 
LEDs. 
2.  Reset SMC
3. After power ON, verify front panel power/sleep 
LED illuminated, and not flashing any error 
sequences indicating a memory failure.
4.  Remove the installed RAID card and drives during 
troubleshooting. Install a known-good SATA drive 
in bay #1 with compatible Mac OS X installed.
5. Verify the video card is supported in this 
computer. Previous model Mac Pro video cards 
may not be compatible. Cross reference the EEE 
Code and GSX part number. 
6.  Verify with known good and compatible ECC 
DIMMs. Installing a non-ECC DIMM will cause all 
memory to run as non-ECC. Note that memory 
from older computers is not compatible and 
cannot be used. See Memory Configuration.
7. Ensure the compatible memory is filled in the 
correct order in the memory slots. If memory 
is not configured for the best performance, 
the “Memory Slot Utility” will appear onscreen 
and recommend an improved configuration. 
To use the utility again go to /System/Library/
CoreServices/Memory Slot Utility
8.  Confirm total memory in System Profiler.
9. Startup with ‘Shift’ key down for safe mode boot. 
Check DiagnosticsReport folder for crash cause.
10.  Startup from original install media, or known 
good boot device with compatible OS X.
11. Run AHT or ASD.

7. Start with ‘Shift’ key to boot 
into safe mode. If computer 
still crashes during boot, place 
the hard drive into a good 
computer to access the Panic 
log.
