Apple Computer on Thursday released a software update for its 13-inch Intel-based MacBooks that it claims will resolve an extremely frustrating issue where some of the notebooks would shut down randomly during use.
"The MacBook SMC Firmware Update v1.1 improves the MacBook's internal monitoring system and addresses issues with unexpected shutdowns," the Mac maker wrote in a support article on its website. "This update is recommended for all MacBook systems, including those that received warranty repair."The Cupertino, Calif.-based company said MacBook owners may use the Software Update feature of Mac OS X or download the MacBook SMC Firmware Update v1.1 from its website.
"If your MacBook is running Mac OS X 10.4.6, you won't be able to see the SMC Update until you update to Mac OS X 10.4.8," Apple noted. "Once you have updated your system software, the SMC Update will appear as an option in Software Updates."
On the other hand, MacBooks running Mac OS X 10.4.7 will be able to download and install the SMC Update, so it is not essential that users update their system software. However, Apple always recommends updating to the latest version of the system software."
