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
