Here is an MP3 where you can hear the moo clearly.

MOO

Sorry for those of you with MooBooks but I couldn't stop laughing. Maybe I need to get out more!

My little black MacBook is moo free - maybe my machine is lactose intolerant!

:p

So, I finally hear this clip, but what is funny is.

This is EXACTLY the sort of sound that my INTEL IMAC 20" makes when starting up. When I start it up, the fan most likely kicks in, and starts running, and then settles down.

It must ALWAYS be on to some extent, but the moooOOOOOOoeeewww, makes it known about five seconds right at start up. And from WAKE up from sleep.

Apple must use the same fan manufacturer for both IMAC and MacBook.

I sold my 17" Intel iMac on eBay (*) but it didn't moo when waking up. What it did was checking the optical drive and briefl turn the fans on. I think an iMac waking up from sleep is the most stylish sound a computer can make. There shouldn't be any rattling or mooing. Try out the hardware check (insert Install CD 1, boot holding "C" down and it's somewhere in the menu bar). It checks everything, including the fans.

But don't be scared if it makes a sound like a hair drier on maximum power: that's normal. It's reassuring to know the fans can cool the mashine in hot climate. If it makes any other sounds, your fans are not ok...



* and the delivery guys broke it and their insurance won't pay... :mad: it was packaged exactly like it's sent out by apple...

Is it me, or is there no "mooing" in that clip? I don't get it.

There is no mooing. But at least the video kept me occupied for at least 2 minutes and 40 seconds.

Even with the volume turned all the way up, I can't hear any mooing in that clip.

Now I here the Moo. I have to say that I feel bad for all of you. My MacBook Pro does not have the CPU whine or the moo. My unit is a Rev B. I admit that when I heard the moo, I laughed really hard, but at the same time that just sucks.

Please Apple come up with a solution.

hope the next generation of intel chip will be more quiet.

this has nothing to do with intel, it has to do with the fan turning on and off.
 
Found this on xlr8:

"I don't think I've ever been this excited about something, which might say something about what my activities (or lack thereof).
What I did was I installed the Mac OS X 10.4.5 8G1454 IOUSBFamily.kext 2.4.0 System Update for iMac with Intel Core Duo and MacBook Pro. The file can be found here:
http://developer.apple.com/hardwaredrivers/download/ubdebug.html
(Note: There's a typo in that link URL (ubdebug.html should be usbdebug.html) - here's the OS X USB debug kits downloads that has the referenced file listed down the page.-Mike)
Download the 'v 240.4.3' file, run it, and install the package that DOES NOT have the '-log' ending. That is, run IOUSBFamily-240.4.3.pkg and NOT IOUSBFamily-240.4.3-log.pkg. Restart your computer, and the whine will be gone. You do not need to run photobooth or do any known workaround to quiet it down...
Also, I think you might need 10.4.7 installed first. It is not an installation requirement, but I believe it is a requirement for the fix to work. I have 10.4.7 installed on my 2.16 MBP 15".

I don't have a macbook or macbook pro, so I can't test it out, but it was originally posted in their forums, then their site manager reposted it on the front page, so I woul dbe willing to bet it works...
 
MacBook MOOOoooo and whine..

No mooing, no whining here.. brand new black MacBook.. no issues at all. Wish I could have said the same for this crappy new HP printer that came with it for only $100. That printer I called HP support about.. they sent a replacement.. the REPLACEMENT was broken too! Luckily, 3rd time was the charm... oh the inhumanity!

I would add I run the thing hard too.. Folding at Home GUI client has been running in Rosetta since the day I picked it up 2 weeks back.. No overheating problems. Fan runs constantly, but it isn't loud and it doesn't MOO! lol
 
ha! i think the people w/"no moo" either have loud rooms, poor hearing or -most commonly- run the machine hard. anything more than safari and itunes pushes the temp to above 68 degrees where the fans run constant (normal, good, no complaints, quiet for fans in a laptop, no issues, freakin great).

the odd behavior only happens under light load, at about 64 degrees
where the fans are set to go on and off at about the same temp.

-+* you all have the moo - hahaha *+-

but maybe not :)
 
We've dealt with your type before, mugtastic. I think it's pretty clear that your little "theory" is simply ignorance and spewing of nonsense, so why don't you start thinking about what you write beforehand? I'm glad you put the "maybe not" in there, otherwise I'd have to rip you to shreds for repeating the same stupid arguments that have been posted and shot down repeatedly.

THANK YOU. :D

This WORKED! The whine is totally gone, with no hacks or workarounds! I'm amazed... and I think this proves that apple can fix the problem if it really wants to.

As for the moo... as bad as ever. So it's not a perfect laptop yet, but it's sure getting there!

edit: nope... spoke too soon. After another reboot (after installing the quicktime update), the whine came back. It's still fixable with a hack, but 2.4.0 is no better than 2.4.6. Oh well.

wow. thats great. i was under the impression that people who have this problem generally think its a setting in the fan programming and people who don't have it say "what are you talking about" or "whats the problem - fans are necessary"

please educate me - what is really going on and what do mooless fans do when the cpu temperature is around 64-65 degrees?

and also, i was responding to someone who "has no moo" but always pushes the macbook above the temp they moo at - so whats ripable about that?
rip to shreds away

Well, I'm glad someone found a fix, but shouldn't Apple's quality control unit be all over this? It seems like they have taken a very light approach to the new machines since they came out in January and May...makes me think about getting a PBG4 instead of a MBP revB...we'll see what becomes of this.

What quality control department?! Mwahahahahahah!!!!

Just kidding yes we have that dept. just couldnt resist to make myself smile. :eek:
 
well they took care of the moos on the macbook pro ahwile ago with a firmware update...so it should only be a matter of time before they do they same with the macbook right? Of course I said the same exact thing like a month ago.

mugtastic-- given what you are charging for your advice, I think skywalker deserves all his money back.
 
a little update

as I posted above, the moo was kicking in for me at around 67-68 C before I tried this, and at 64-65 after I tried it.

Well, happily, a few days later, it is once again starting at 67-68 C. I don't know why, but it's a good thing, as far as I'm concerned. So perhaps whatever this accomplishes is temporary? :confused:
 
Didn't work for me. Kicks in at 65 which is the exact idling temp when I have my FW drive plugged in. :rolleyes:
 
i've been reading up on the MacBook for ages and i just wanted to mention that i've had my macbook since for 5 days and for just sitting here posting and running Adium (chat client) its running at 56 degrees. typically it never exceeds 80, and thats like...ripping a dvd or something. burning a dvd or using iMovie HD i get somewhere between 60 and 70 (75 max.). I never really heard a "moo" unless the moo is just the fan sorta starting and stopping a little. it only did that once i think and i dont even remember when. my fan doesnt really even start until its up over 75. theres never been a whine or a moo. do i have the flawless macbook or something?
 
MooFix Widget

Unfortunately this did not work on my MacBook so I decided to create a dashboard widget which prevents the mooing noise. I have also created a petition to apple for them to release an official fix.
