Late Tuesday, Apple released its SMC Firmware Update 1.3 for the company’s 13″ polycarbonate (black and white non-unibody) MacBook notebooks released in early 2009. The update, a 557 kilobyte download, works to clear a performance issue wherein the notebook may slow down when booted while using battery power only. This SMC Update improves startup time when starting up from the battery.
The update requires Mac OS X 10.5 or later to install and run.
