Greetings MB owners, last night (DK time), Apple released a firmware update, fixing fan issues in the MacBook's. In my thread about this, many MooBook owners reports, that it got rid of the moo for them. How did this firmware update affect your MacBook? I never had moo on my MacBook, but the firmware update has definiantly made it run 10 C degrees cooler, and make it generally snappier, for example opening applications and Finder windows. Remember this is multiple choice. Also, specify whether your MacBook moo'ed before the firmware update.
