Mac Pro Firmware Updates
Firmware is software written into memory circuits, such as flash memory, that will hold the software code indefinitely, even when power is removed from the hardware. Firmware on Intel Mac computers is designed to be updated if necessary through a software update.
EFI firmware updates update the Boot ROM, and SMC updates update the System Management Controller firmware.The SMC manages fans and other environmental parameters that are independent of the Boot ROM.
Firmware symptoms can be easily mistaken for hardware issues (e.g., overheating issues, fan noise issues, etc.). Always check both EFI and SMC firmware versions and update if necessary before replacing any hardware components.
The following lists describe the type of symptoms that may be resolved by updating the EFI and SMC firmware.
Symptoms that may be resolved by updating EFI firmware:
•Cannot eject media (various conditions)
•No video on start up
•Blue system failure screens in Windows XP/Vista
•Not waking or sleeping when expected
•Bad media taking too long to eject (including holding mouse button down at startup taking minutes to eject)
Symptoms that may be resolved by updating SMC firmware:
•Fan related behavior (excessive speed or noise)
•Loud audible clicking from some fans
•Thermal shut down or warnings
•Diagnostics reporting failures
•Sleep/wake issues
•Intermittent shut down
•SMC causes bad/missing ambient sensor to cause the computer to go to sleep
•Hangs, black screen on restart from Windows

•Quick power cycle causes Memory Processor Board Diagnostic LEDs and CPU Overtemp LEDs to illuminate solidly
Important: Since the SMC firmware is stored on both the backplane board and processor board, it is important that the version of SMC firmware is the same on both boards.
Please follow the steps outlined in KnowledgeBase article HT1557,“About Firmware Updates for Intel-based Macs,”to perform an EFI and/or SMC firmware update. Information about firmware versions for Intel Macs can be found in KnowledgeBase article HT1237,“EFI and SMC Firmware Updates for Intel-based Macs.”

Common Reset Procedures
The following reset procedures are often helpful in troubleshooting Mac Pro issues.
Resetting the System Management Controller (SMC)
The System Management Controller (SMC) controls all power functions for the computer. If the computer is experiencing any power issue, resetting the SMC may resolve it.The SMC controls several functions, including:
•Telling the computer when to turn on, turn off, sleep, wake, idle, and so forth
•Handling system resets from various commands
•Controlling the fans
It is also recommended that the SMC be reset after a backplane board or processor board is replaced as part of a repair.
Note that resetting the SMC does not reset the PRAM. Resetting the SMC will not resolve issues in which the computer is unresponsive—in these situations, restarting the computer generally works. If the computer isn’t responding, perform these steps one at a time, in the following order, until the issue has been resolved:
1.Force Quit (Option-Command-Escape)
2.Restart (Control-Command-Power)
3.Force Shut Down (press the power button for 10 seconds)
Resetting the SMC can resolve some computer issues such as not starting up, not displaying video, sleep issues, fan noise issues, and so forth. If the computer still exhibits these types of issues after you’ve restarted the computer, try resetting the SMC by removing AC power:
1.From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2.Unplug the AC power cord.
3.Wait at least 15 seconds.
4.Plug the power cord back in, making sure the power button is not being pressed at the time.
5.Press the power button to start up the computer.
