MACBULLET  If that is true, I probably won't apply the update because the mirror widget is essential for me to get rid of my cpu whine  
(Version 1.0)

PATMOSPHERE  Try opening, then closing Comic Life (should have came with the MBP).

Thats what I do to get rid of the CPU whine  
(Version 1.0)

YADDAYADDA  I can confirm that the whine fixes I know of STOP WORKING after installing the update. Neither the mirror widget nor photo booth (clicking on an image and closing) nor comic life help.

If you have sensitive ears, wait before installing this.

C3ZV3  Also confirmed. After installing this update, force-quitting PhotoBooth does /not/ stop the whine on a MacBook Pro with serial #W8612*.

Apparently no uninstall option. At least reinstalling OSX is a lot faster than reinstalling XP.

SOREN0  If you have problems with your MacBook Pro, Call Apple about this so they will be able to look into the issue.

Thanks.

If you post it here, Apple wont read it.

DYINOSARS  It does seem that the mirror widget trick doesn't work anymore...as well as magicnoisekiller. I have been using QuietMPB, but I don't like the fact that it uses battery. Does anyone know if there is a way to uninstall this update?
