Mac Pro Firmware Updates

Firmware is software written into memory circuits, such as ash memory, that will hold the software code indenitely, 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 rmware updates update the Boot ROM, and SMC updates update the System Management Controller rmware. 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 rmware 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 rmware.

Symptoms that may be resolved by updating EFI rmware:

• 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 rmware:

• 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

2010-08-31

Mac Pro (Mid 2010) General Troubleshooting — Wireless Troubleshooting 20

• Quick power cycle causes Memory Processor Board Diagnostic LEDs and CPU Overtemp LEDs to illuminate solidly

Important: Since the SMC rmware is stored on both the backplane board and processor board, it is important that the version of SMC rmware 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 rmware update. Information about

rmware versions for Intel Macs can be found in KnowledgeBase article HT1237, “EFI and SMC

Firmware Updates for Intel-based Macs.”

Memory Diagnostic LEDs

The single-processor and dual-processor boards include a set of diagnostic memory LEDs. The following illustrations show the location of each LED and its associated DIMM slot.

Single-Processor Board

Dual-Processor Board

To diagnose memory issues, start up the computer and check the diagnostic memory LEDs. An illuminated, red LED indicates its associated DIMM may be poorly seated or failed.

2010-08-31

Note that Apple System Proler does not report unseated or failed memory. You must use the memory LEDs to locate DIMM issues.

Mac Pro (Mid 2010) General Troubleshooting — Memory Diagnostic LEDs 24

Troubleshooting Memory LEDs

Follow this procedure when troubleshooting each DIMM identied by a red LED:

1. Remove and reseat DIMM.

2. Restart computer. If associated LED is no longer illuminated, issue is resolved.

3. If associated LED remains illuminated, replace DIMM with new DIMM.

4. Restart computer and verify LED is no longer illuminated.

There is one exception. If two LEDs illuminate at the same time for the 3 DIMM and 4 DIMM slots or for the 7 DIMM and 8 DIMM slots, check both DIMMs using this process:

Check Result Action

1. Remove both DIMMs identied by

illuminated LEDs. Set DIMM 4 (or DIMM 8) aside, and reseat DIMM 3 (or DIMM 7). Restart computer. Is DIMM 3 (or DIMM 7) LED illuminated?

2. Reinstall DIMM 4 (or DIMM 8). Restart computer. Is one or both LEDs illuminated?

Yes Replace DIMM 3 (or DIMM 7) with

new DIMM. Go to step 2.

No Go to step 2.

Yes Replace DIMM 4 (or DIMM 8) with

new DIMM.

No Issue resolved.

Mac Pro (Mid 2010) General Troubleshooting — Block Diagram 29

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 o, 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 o).

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.
