Apple Releases Display Brightness Update for New 21.5-Inch iMac

Can anyone tell me if this fixes the high pitched screen noise?

I'm not experiencing any problems with mine. I appear to have a perfect one. I'm afraid of doing this update

Damnit, i sure hope this fixes it! I can't test right now because i'm waiting for my replacement. Should come next week.. I suffered from the yellow screen, brightness noise issue & seagate harddrive rumble. If anybody with the brightness noise would be so kind of updating; do let us know the effect!!

My 24inch white core2 duo imac had that brightness buzz. I sent it back 3 times cus it made me mental. Hope my new 27" that is arriving tomorrow carries no such issues. that's insane if they haven't solved it in 3+ years:rolleyes:

Wow, and just today and I was saddened because I felt like my iMacs screen was to dim compared to the last mbp I had. I do have a yellow tint screen though, and not sure if I should have it replaced if they aren't fixed yet. But I just installed this update and im almost positive they up'ed the brightness levels a bit. My background which is a lightning bolt now appears to pop a good bit more on full brightness. I never had any screen buzzing issues or whatever, and still don't.

My iMac hasn't had any buzzing problems, but there is a small tinge of yellow along the bottom and right side... not very noticeable AT ALL, but this update definitely makes the screen pop more than before. Maybe it's just a mind game, but it looks great!

Holy crap! This has made my screen about 20% brighter! :O

Maybe I should double it as a lighthouse...

My first Gen iMac 24” makes a high pitch whine when it is dimmed. SO in order to dim it I needed to download a program called Shades (http://www.charcoaldesign.co.uk/shades) to dim it with out that annoying noise. After Three and a half years it is about time Apple looked into it.

Well I went ahead and installed the update and it clearly makes the screen much brighter.
Not sure exactly what they did here. But you can no doubt see a big difference

I cannot seem to get mine shipped. Maybe this is the hold up, but per Apple it is the Magic Pad that is supposedly holding the order up. :confused:
