Is palmrest harmful for macbook pro 15 retina? I recently got a new Macbook Pro 15 retina. I already have a keyboard cover on it, and earlier today I put a palmrest and trackpad cover on it as well.

However, This Apple support website says that applying palmrests and keyboard covers might actually be harmful to the screen and display. On the other hand, interestingly though, this Apple sales website  itself lists Moshi Palmrest as one of its supported Mac accessories.

I'm thinking applying the palmrest will not do any damage as such? Please help!

Thank You.
Any palmrest has a chance that it will be in contact with the screen, when the laptop's lid is closed.

Having anything in contact with the screen raises the risk that the screen may become damaged - at least on the surface of the screen.
