Yea I'm torn. I don't want to have to spend a day reinstalling all my apps etc.
I just feel with Apples QC lately esp screens, I may get something better or worse. At this point, based on what I've seen, I do not want a samsung screen. Also its hard to hear the creaks and see the screens in the brightly lit noisy Apple store. Problem is by the time I go online an order one of those impossible to get P5 pentalobe screwdrivers I will be past my return policy. Worse part is once I get that perfect screen and no creaks then I will get kernel panics indicating bad ram.
At the end of the day its not that bad its just the fact I feel a $3K freekin laptop should have no issues at all period.
Crap comes out of China in the millions and blows and I guess we need to learn to live with it. Im so tempted to return these machines and get the new Mac pro thats made in Texas. At least they are paid more the $10 a day!
Stick with what you have. Trust me.
I went through the same process with the ivy bridge rmbp before abandoning the system altogether.
My first Haswell was a samsung screen, and like many reported on here, it had the usual dark corners, unevenness etc, loads of creaking, and just wasn't a very good machine.
My replacement was an LG, and sounds exactly like the one you received. Slightly darker or warmer tone on the right side, and slight creak on the right side too.
It did creak all over at first, but reseating the back plate after I changed the thermal paste seemed to fix most of it. I think the cause here is that the screws are too loose (at least in my case). Over tightened screws are also a cause of it as well.
Now the thing people need to distinguish, is if the noise is actually creaking, or the sound of one of the thermal mechanisms within the macbook itself.
The place where the logo is, emits a clicky metallic sound because of this. You can fix it easily by opening the back cover and removing it.
There's a thread buried somewhere on here that goes into detail about how to do it. It doesn't affect the running of the machine at all and is perfectly safe to do.
If it's the sound I'm thinking of, then you will almost certainly hear this ticking when the system is under heavy load and the casing temperature is increased significantly. Usually this causes a constant ticking noise till the machine cools down, without the user even touching the computer itself.
It's very annoying, but is easily fixable for those who have a pentalobe lying around.
