About MacBook SMC Update 1.3

This SMC Update improves startup time on some MacBook computers when starting up from the battery.

Polycarbonate MacBook computers released in early 2009 may display slower performance when started up using battery power only.  Restarting using battery power may not clear the condition.

You can resolve this issue by downloading and applying this update.

To determine if your computer is eligible for this update, see EFI and SMC firmware updates for Intel-based Mac.
