Important: Ensure the correct version Mac OS X and latest software and firmware updates 
have been applied before you begin troubleshooting. Computers sometimes exhibit 
symptoms that indicate the wrong Mac OS X system software is installed. 

Firmware is the name given to software that is 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 by 
running the Mac OS X Software Update check (available in the Apple menu) while computer is 
connected to the Internet. For more information about firmware updates, refer to:
