Is your new Mac laptop making barnyard noises or suffering from insomnia? Apple has released a pair of updates to address two specific, annoying issues that have cropped up with the MacBook and MacBook Pro.
The MacBook SMC Firmware Update adjusts the fan behavior of the entry-level notebook to calm its inner cow. The update apparently gets rid of the "moo" sound caused by the MacBook's fan repeatedly spinning up and powering down as it regulates the processor temperature. As this is a firmware update, make sure the installation process isn't interrupted. The installer is a 420K download, requires Mac OS X 10.4.7, and works only on the MacBook.
MacBook Pro owners can install ExpressCard Update 1.0, a 492K download that fixes a problem where the laptop would fail to go to sleep if some cards are left in the ExpressCard slot.
