Keyboard update killed the PhotoBooth "fix" for whine

I was using the PhotoBooth "fix" to kill the horrible whine, whereas I would launch Photo Booth, click on a thumbnail and then quit the application and the whine was gone. Well, after installing the keyboard update 1.0 released today, quitting PhotoBooth means the whine is back...

MacBook Pro 2.0Ghz, Mac OS X (10.4.6), 1Gb RAM

I hope this update fixes the response of my keyboard which has been awful. I'm glad for the update.

I can confirm the problem on my MBP W12 1.8. After the update, no whine fix works any longer. Please Apple, if you don't care about solving our dire problems, would you at least refrain from making them worse?

How about the processor CHUD fix?

Does that still work with the keyboard update?

Sounds like this is one to avoid.

Yes, just applied it, now I can't get rid of the blasted noise. Since this is the first time i've experienced the noise for any duration (since the mirror trick), I've done some more experimentation on it:

It's independent of the volume setting. Changing the volume does not affect it at all. Its also FAR worse when plugged into my speakers. At the third of the volume bar, it drowns out regular sound coming from the unit. Some of my contacts have complained about it coming through iChat (!!!?).

I will have to be returning this unit to apple now for service. This is ridiculous. At least before the latest update the problem was manageable. Now the machine is a useless noise maker.

On mine quietmbp takes up 10-15% cpu, whereas the mirror trick, etc take up almost no cpu time (99.9% idle in top). even 5% is unacceptable.

I performed the update and the CHUD processor switch off technique still works to quiet the MBP.

Switch it off rather than increase CPU workload = premature risk of early death.

I can confirm that the Photobooth and Mirror techniques no longer work.

I would find that the MBP ran hotter when using these "fixes". I am guessing that Apple has begun examining this and has issued the keyboard update to stop the heat problem due to a bug the whine fixes were accidentally exploiting.

It now remains to fix the whine.

Please mark this as helpful if so.

Ok. Something is really strange here. I also used QuietMBP successfully in the past, but since the PhotoBooth with quit fix was working I put it aside. Well now that the PhotoBooth is not working, I went back to the mirror and the QuietMBP fixes. Both are working, as long as they are open, which is, in my view, an unacceptable fix whereas you loose 8 -12% of your CPU in some cases.

So decided to go back home, closed the lid and packed up. Upon un-sleeping the computer at home... no whine.... So I tried it many times.. Here's what is working for me now...

If I restart, the whine comes up.
Open up QuietMBP and adjust it appropriately, silencing the whine.
Then, close the lid, putting the computer to sleep.
Give it a couple of minutes, and then reopen the screen. The whine is gone... but then of course, all the time QuietMBP was up... so no mistery there...
But now, quit QuietMBP. Still no whine... and full CPU... Before, at least for me, quitting QuietMBP would immediately bring back the whine...

Apple?

Yes this works for me also.

The whine is very subdued, in my case exactly like when on AC power.

Great find. I suspect that the mirror fix may also work with a sleep before switching off.

Does anyone "read" posts on here, or just reply to old ones and then start new ones? It's always new threads repeating posts on the same subject over and over...I'd love to see new threads on different topics - where the **** is the moderator on here?

I think you have yourself failed to read this tread. "Your" technique in the other thread no longer works. Thats what this thread is about.

I was referring to the red-sweater blog there Aussie. The "technique" is not mine - it's been around for a while. The fact that the "technique" no longer works post-keyboard update was in that thread.

And yes, deleting the "family" kernel extension (another new plugin possibility discussed on yet another new thread) has also been explored in the forum if you would bother to look.
