The Mac press has been full of tales lately of Macbooks inexplicably shutting down. Today, Apple announced a cure for this annoying habit, known oddly enough as MacBook Shutdown. In an advisory, the Intel OEM issued instructions to owners to install SMC Firmware update 1.1. Recommended for all MacBook owners, the update improves the "internal monitoring system and addresses issues with unexpected shutdowns".
MacBook owners running Mac OS X 10.4.6 will need to go up a couple of notches to Mac OS X 10.4.8 before they can install the update.
Apple's advisory is here. ®
