I'm still thinking either to get the non-retina or the retina. But due to budget limit, I only able to get the 128gb with education discount at most. Any comment about the non-retina?

If I am not mistaken, anti reflective coating issues got no expiry. Someone posted much earlier that they have replacement program for this issue. But if the unit is a recent buy <7 days, exchange 1 to 1, if not they replace the lcd which unfortunately may take some time.

I too have issues on mine but in my opinion is not so severe. It like lines here and there which during operation does not impede on the usage experience, so I do not mind.

Yes I too have the same sort of marks, I think its also due to the keys rubbing. Anyways it does not effect my viewing so I'm good to go so far..

I just got back mine few days back - it took 2-3days to repair only and it's FOC

claim for staingate? if yes, can straight go to 1u mac city to give them service 3-5 working days get back your macbook

Just sent my rMBP for warranty claim for the screen marks (staingate issue) to mac city in 1U. Hopefully no issues on the warranty claim

Apparently my claim was sucessfull and my laptop was ready yesterday, but i no time go collect it

There must be an app that is still linked to your hard drive. Also it could be an open file etc. Did you try to see in the 'Force Quit' menu?

Also does this issue happens on a particular usb or on all usb ports?

quickly backup the content before something happens. looks like it gonna corrupt.

If you haven't tried.

Switch off all extensions in safari. Then on 1 by 1 and check for the useability. If it crashes, then you will knw the culprit.

and/or check for any updates in app store.

When I upgraded mine to sierra, got the same issue, it was one of my extensions that I installed for Facebook. Now its all good after determining the rogue extension app.
