Attention MacBook owners: fire up Software Update to get the latest MacBook SMC Firmware Update. From the updater: 'The SMC Firmware Update adjusts fan behavior in the MacBook. The updater application will be installed in the /Applications/Utilities folder. Please follow the instructions in the updater application to complete the process.'
Could this spell the end of the Mooing MacBooks? Only time can tell.
Thanks to everyone who sent this in.
