Apple fixes some late-2008 (unibody) MacBook issues with dual updates

Apple has released a firmware update for its late-2008 (unibody) 2008 MacBook, MacBook Pro, and MacBook Air computer models. In a first (as far as we know), Apple is requiring two updates for each model: the EFI Firmware update and the SMC Firmware update. Apple previously released a different firmware update for the unibody MacBooks and MacBook Pros.

Release notes state:

"These updates address system stability issues, as well as problems with the computers properly sensing the presence of magsafe power adaptor attachment and battery indicator lights."

However, it's not known how many of the myriad issues we've chronicled are actually fixed. To recap:

• Late-2008 MacBooks: More on freeze-on-wake, wireless problems, trackpad issues
• MacBooks crashing with aluminum keyboards
• Keys Improperly installed on some MacBooks
• Unibody (Late-2008) MacBooks have a relatively audible hum
• Late-2008 MacBooks: Fan noise
• Late-2008 MacBooks: Battery issues
• MacBook (Late-2008) screen brightness undesirably varies
• Late-2008 MacBooks: Migration Assistant fails

Instructions for applying the EFI firmware updates are located here, and instructions for applying the SMC firmware updates are available here.
