Question: My Macbook makes the high pitched hum, but if I turn on photo booth it goes away. Not as bad as it once was, but it is still there, only happens when I am on battery power. Any thoughts?


Thanks

That's the sound my laptop makes. Does that beat the MacBook's mooing issue.

No.

That's the whine issue.

I was able to get my MacBook to stop mooing with the moofix widget. The PMU reset did not work.

I just got my MacBook yesterday and its a mooer. The PMU reset didn't work. What I don't understand with the widget is do you just activate it when the mooing starts and then you can go back to doing your work or do you have to leave the dashboard open or what?

To the poster above, why are you so SURE that Apple will NEVER fix this problem? They released a firmware update to fix the fan issue with the MacBook Pros so why not the MacBook?

Cause it's been so long...It only took about a month for the firmware to comeout for the MBP version. I haven't used the widget yet, but it sounds like it could drain battery life when it's not plugged in.

did the reset. no change. osx update no change.


apple needs to send out a fix so the fans go on low but steady at an appropriate temp. like mine do now at 70 degrees.

i think apple thought setting it this way would pre empt constant fan noise at light loads like surfing the net and they would be hailed as having an even quieter notebook computer. they were wrong.

it is a great computer though.

The fix should be to have the fans runs like HVAC systems do: instead of a single temperature "trigger", they need a trigger to turn the fan on (say 67 degrees), and another one to turn it off again (say 64 degrees). That gives a 3 degree dead band where the fan stays in its current state between the endpoints.

absolutely - meant to say on at higher temp, off at lower. but maybe on at 70 off at 60? longer time between cycles.

tried the widget - made the temp. read 80+ and the fans were on high non-stop, and i couldn't just turn the widget off - had to restart then trash it - i choose the soft fan moo.

just started to notice the whine but its sooo quiet i assume other peoples are MUCH louder. goes away with photo booth though.
 
How do you find out the CPU temperature?

Bought my Macbook about a month ago. Never noticed any mooing. Tried hard to hear it too, never noticed it.

Not sure what if anything changed, but last night I was in a completely silent room which is unusual, and I had been running the Macbook hard to it was hotter than usual, and I had just applied a security update to Mac OS X, when I heard it. Its very faint. I have to put my ear to the keyboard, but there it was, the distinct mooing sound.

I think it is silly to have a fan spin up and down so quickly. Its not useful. Apple needs to extend the time the fan stays on. I’m still hoping its a matter of time before a firmware fix it released. Seems like it should be easy and should have been done by now. Either have a bigger dead band, or have a minimum fan on time, something, anything, but spin up and down in a second just doesn't make sense.

I tried the widget, was kind of freaked out by temperatures that high, restarted then trashed it. Not worth it.

am i the only one that didnt have high temp. results from using the widget? Mine just stayed around 70 degrees with the fan constantly running at a low quiet pace.
 
my Dell's been mooing for 4 years..

and no-one seems upset.

I say- more animal noises from IT!

Btw my Macbook gets hot, but doesn;t moo.
 
Fix doesn't work. I tried it, waited a while to see if the conditions would occur again for mooing, and it did.

When the temp is around 69c on my system, the mooing occurs. I recently upgraded to 2gig of memory. I don't know if that's helped cause it. It seems to idle hotter and certainly runs hotter, I assume because its swapping less and actually doing something instead. Its awesome fast w 2 gig.

yes they do... I mean its quite funny... My MacBook had yellowing (recognised by apple so replaced parts for free) so I went to my local apple dealer, told him: my MacBook is ill and before I opened the mac he said: o you mean the mooo, we'll fix that... and then he saw the yellowing: o yes and that too ;-) so now 30min later I have my MacBook back wih a new white part... and the moo is allso gone...

Please submit this to MacRumors as news and also make a new post that Apple fixed your moo. People need to know that they can now do this.

ok but this was my local apple dealer, not an Apple Store... (the replacement of yellowing parts was known allready)
so fixing the moo is maybe something one of their techguys found out and fixes... nothing to do with apple... but maybe they got instructions from apple, didn't asked him... I was in a hurry (and very happy they fixed it in 30min, instead of the 3day waiting they told me, but telling them I need it for work changed that :D)

www.itpro.be is the site from that store...

the mooing is back (but less loud than before...) so I didn't noticed it before today... the fans rev up but not as much as they used to do so that's why i didn't hear it before I guess... and now its very silent here and then... yep it's back... :s

hmmzzz...
 
just installed it...

instead of allways going up and down, the fan now runs at a slow & continuos speed all the time...

so its really fixed this time instead of being a little less audible... and indeed apple did fix it...
 
Installed this on my MacBook and what used to run at 65C to 75C is now running at a nice 40C.... got to 50C with all apps open including PS CS2 and Dreamweaver.

Any idea if there is a fix due for the MacBook Pro? Kinda talked myself into getting one and selling my iMac and MacBook so would be nice
