MacBook firmware update fixes shutdown issue

Apple on Thursday released a firmware update for its MacBook line of computers that fixes a problem that caused the MacBook to shutdown without warning.

“Apple has identified an issue that causes a small percentage of MacBooks to shutdown intermittently,” Apple said in a statement provided to Macworld. “Today we released a downloadable firmware update that addresses this issue, and eliminates the need for customers to send their systems in for warranty service.”

The firmware update improves the MacBook’s internal monitoring system, according to notes provided by Apple. You will need to have Mac OS X 10.4.7 or higher to run the update.

Apple said the update is recommended for all MacBook systems, including those that received warranty repair. The firmware update is available from Apple's Web site.
