I've been looking at this article - http://support.apple.com/kb/HT2213

I have a few macs, and a 2 year old Macbook Pro with annoying fans which never seem to stop. I've read that the firmware update which caused the change in the fans behaviour can be downgraded.

However the article above says:
This CD cannot be used to return an Intel-based Macintosh computer's firmware to a previous version if a successful update has already been performed.

So how can I get back to an older version of the firmware and make the Macbook more user friendly?

Also see here - http://www.macworld.com/article/140845/2009/05/mbpsmcfirmware.html

Any help would be appreciated.

    The fans may be indicative of a larger problem with the batteries:

    So I guess my ultimate question is - can I restore or downgrade the MPB to an older firmware version?


    Short of a logicboard replacement, no.

    Only Apple could answer that. This is a user to user forum.
