    Hello all,
    I am curious about something. My question is, could the corner of a piece of paper scratch the display of a retina MacBook Pro in any way. I'm talking about the edge of the paper in the corner where two sides meet. Even if it's a micro scratch I would still like to know if it is possible.

    Almost anything is possible. Give it a try. Let us know how it works out.

    No, it already happened, and I found a small scratch under direct light, but I was wondering if this could have caused this, or it was something else.

    I wouldn't think paper could actually scratch glass, but perhaps any coatings that are on the screen.

    I find it funny how things I wouldn't expect to scratch screens do; it's frustrating really. As soon as it happens though, I can just enjoy my hardware and not worry so much about the little things. It's kind of like that first scuff on a new pair of shoes. :D

    I know first-hand that paper edges can be rather sharp - but will it be enough to scratch glass? No idea. Do an experiment ;)

    If I remember my Mohs Hardness Scale from middle school science, it shouldn't be possible for a softer material to scratch a harder one. My bet would be on no. This scratch must have come from somewhere else. The retina screens are glass, right?

    Can anyone test this for me with a piece of paper, I need the iPhone flashlight to see it, could someone try it, I'm extremely OCD and scared to.

    Perhaps you should try yourself, instead of asking someone to scratch their laptop.

    Edit:
    I thought the rMBP display was plastic as they removed the glass for space,

    No.

    To actually scratch something, anything, the material scratching the other must have a higher hardness. Paper is not harder than glass.

    Nope, it's still glass, they just glue it directly to the display itself.

    I agree. I was like, "what@!". Scratch your own device. Geez.:mad:

    I would if I wasn't so OCD, I'm on 20mg of lexapro and I still can't test it myself, someone used a pin once to test something, someone might do it, I'm not forcing anyone.

    I'm fairly certain that the screen cover on Macbooks is glass. (You need to keep in mind that thin glass tends to have a similar 'tapped' sound to plastic as opposed to thicker glass. A good example of this is high quality wine glasses. Tapping them produces a duller feel because it's less rigid and therefore a lower frequency sound)

    With that said, it shouldn't be possible to mark glass with paper. Assuming that the paper in question is the usual cellulose/plant based stuff. Paper simply doesn't have the hardness to achieve it. In fact, you could probably take something a bit harder like a plastic pen cap and it still wouldn't leave a scratch.

    I can't confirm if there is a coating on the glossy MacBook screen. A casual search says no'. So however your mark came to be or if it's even a permanent mark, I'm fairly confident it wasn't paper.

    Definitely it was something else. Please list all the materials in your house of whatever hardness so that we can test them 1-by-1 :rolleyes:

    I've only had this computer for 2 days, and that's all it's really come in contact with, I assume it came from the factory that way?

    If you are that OCD you need to get away from these forums!

    Just relax and try to enjoy your laptop.

    Tell me about it, 2012 was bad because of the forums, but now I'm just asking a question to help me get back to doing other more important things. :)

    I understand and I know you are trying to make sure everything is perfect. But try taking a deep breath and relaxing. If you had to use a flashlight to see this small scratch you might just be able to live with it. If all else is working perfectly, why take a chance the replacement is bad.

    I got a new MBPro retina to be delivered on Monday and a MB Air coming a few days after and have found Apple hardware to be well above the other junk on the market. I special ordered a new W540 from the factory and it would not even boot up!

    Compared to this you are doing good! Enjoy!
