Apple just released a firmware update for all us MacBook owners that adjusts the fan behavior. This firmware update may be a direct result of all the complaints of heat and strange fan noises (a.k.a. Mooing). I installed it and the firmware update scared the crap out of me. It turns your fan on full blast for some reason during the update. I had no idea the MacBook fan could be so loud.
I'm wondering how this update will affect heat, battery life and fan noise. Also, will the dreaded Moo sound become a footnote in history? Personally I never heard the "Moo" very often and when I did it was fairly quiet.
Now that I've updated I hear a low fan noise that I don't recall before. It sounds like the fan remains on low spin continuously. If it keeps heat down that's fine with me.
Odd, I'm starting to feel a bit sentimental and I'm already missing my MooBook.
