No problems before or after the update with my i7.

I've received 2 faulty 27â€³ iMac's since November 2009. I noticed the flickering on the first machine almost immediately and ordered a replacement. And the replacement turned up with exactly the same problem. I installed this Firmware update and it did absolutely nothing to remedy the problem. And I'm still having constant flickering and screen going black. I'm now waiting on a third machine. So fingers crossed it won't flicker or I'll have to return it for a full refund. Not going to try for a 4th machine!

Now we just need Apple to fix the glare of those screens;-)

I wish I had one of these giant beauties. Bought my 20 inch Aluminum Glass iMac back when it first came out. Still loving it.

Just to join the Merry Band, I've had no problems either. I too have run the patch and also have had no glitches.

To echo most of the comments I've seen, I had no problem with my Core i7 27-inch iMac prior to the update, but ran it anyway. Subsequent to the update, there were no glitches. So there you go.

Peace,
Gene

Yes. I haven't had any display problems, but applied the patch anyway, without any difficulty. Let's hope this solves problems for a lot of people (but because of this problem there will be a lot of nice buys at the Refurb Store after the holidays!!).
