Finally!

This has been a known issue with hundreds upon hundreds of posts on Apple's support forums since the computer came out in 2008. I'm impressed it only took 3.5 years to release a fix. Let's hope it actually fixes it and doesn't create any new problems.

Good on Apple for targeting this for all of the recent OSs.

So far so good! The flicker was annoying enough that I just set my computer to "higher performance" (the 9600M GT chip) and left it there forever. Not a single flicker since the update.

My workaround didn't bother me because most of what I do benefits from the extra graphics horsepower to some extent or another, but on those rare occasions that I can't be plugged in and just wanted to surf for the internet or write or whatever (like on an airplane), the loss of battery life and extra heat has been a pain in the… lap.

That loud beep that happens sometimes after an efi firmware updated scared the bejeezus out of me. I thought something awful happened. It's apparently normal. Never happened to me before, though.

I have this problem too occasionally. Didn't think there's ever be an update to fix it, though.

What is with all these firmware updates coming out lately? We barely ever used to see firmware updates for devices past their warranty expiry, now there seems to be an update for every model made since '08! Perhaps Tim is authorising them whereas Steve wouldn't. :o

Crazy!

I had just bought my Late 2008 MBP 15" a week ago and thought I had made a huge mistake as I had sold my 2010 MBP 13" which had been working flawlessly only for wanting something with a bigger screen was my reason for selling. I had only just recently found out about the flickering screen with 15" 9400 nvida cards. I was disappointed to say the least but, now it seems as God sent to get this firmware update within a matter of a week of owning this computer! I feel bad for the people that have waited almost 4 years to get this fixed and for me to get this within a week well... what can I say! :)
