Apple MacBook SMC Firmware Updater... This firmware update addresses an issue with certain MacBook and MacBook Pro models from 2007-2008 that prevents them from charging with new power adapters.
Your computer's power cord must be connected and plugged into a working power source, or your battery must be at least 25% charged.
For more information see http://support.apple.com/kb/TS3499">.
When your computer restarts a gray screen will appear with a status bar to indicate the progress of the update.
I installed SMC Firmware 1.1 on my 2 GHz MacBook, which was *not* exhibiting the sudden shutdown problem as far as I could tell, as is recommended by Apple. There have been no issues with the update.
By keeping the operating temperature lower, it shouldn't get to the point where the heatsink is expanding so much that it makes contact with the sensor cable, causing the short circuit.
Having said that, I've had my heatsink replaced under warranty. I still installed this update. The fans seem to be spinning slightly faster at idle, which should keep temps down.
Are we sure the issue really was the heatsink? Certainly that *seemed* like a solution, but perhaps it was not the real solution or a complete solution? Perhaps replacing the heatsink only reduced the problem, with the underlying problem remaining, such that given enough high processor use it would still shut down, just requiring more than before. This is purely speculation on my part, mind you, but Apple is recommending firmware update 1.1 even for those who had the heatsink replaced (indeed, even for those with MacBooks not exhibiting the problem now.) I think it's safe to say that you should install this update. FYI, I installed it on my MacBook which was not exhibiting the problem and have seen no problems with it.
Actually, I think this firmware update simply bypasses the shutdown problem. I ve seen lots of pictures, in which the cable was melted enough. Ok, fine, I am going to install it, but how should I know if my cable burns and mets inside?
If I had the RSS problem, I wouldn't use this firmware, because I couldn't demonstrate the problem again. And I don't want a notebook which has got some loose wires...
Incase your wondering this will only fix the issue most of the time. It doesn't always fix the issue and if the issue is not fixed then you actually need the heat sink.
now the sound from the fan finally ended, took it to get fixed to an apple store and they told me to wait for this update... great job apple!!!
without this fix, i nearly couldnt even take the macbook to libraries as it made that horrible sound (the one that looked like the fan was gonna start but then didnt... I know most of the macbook users know what im talking about)....
now we only need to improve bootcamp so that the mousepad works as in osx!!!
thats because they probably have new
If they have early versions like mine, then they should definately know what Im talking about, its a bug and apple had to fix it, it did exist
Updated my BlackBook today because this was in the 'auto update' section. My BlackBook purchased 1.5 months ago was already as quiet as a mouse, but i updated anyhow.
Thus far...2-hours later of constant use, my BlackBook is still as quiet as a mouse. No new noises or fan spinning or anything.
I have a feeling it will simply make my fan run more efficiently on an already quiet macbook.
Stopped the occasional mooing completely after 3-4 hours of continuous use. I don't notice any baseline increase in fan noise either. CPU temps appear unchanged on average (using the Hardware Monitor app) compared to the same time yesterday at home with same indoor temp.
I read on another forum that a MacBook user, who did not have a mooing MB, applied this update, and then he noticed his fan on all the time. Now his silent MacBook is making noise, noise from the fan constantly spinning. Just a word of warning to those without the moo who like their MacBook as it is -- IF IT AIN'T BROKE, DON'T FIX IT! I do not think I am going to apply this update because I don't want my fan spinning all the time.
I agree. The quiet MacBook now has a constant fan noise (though I wouldn't call it noise -- a very faint white-noise). Only really noticable when in absolute quiet. AND my MB does run cooler (was between 65 and 75C -- now constantly less than 58C; using CoreDuo Temp).
gazman - with the fan running all the time, yes, it should run cooler. But notebooks are designed to handle a little heat, and Apple originally designed the MacBook that way, so is it necessary to run the fan all the time? No. Apple is forced to make the fan all the time as the only solutioin to fix the mooing in certain MacBooks.
The question is, do you want to put up with the noise of the fan running all the time? I work in a silent environment and prefer it to stay that way.

No, we don't.
Three of my friends have MacBooks; none have the moo'ing I hear complained about on the Internet non-stop.
