Do you use a cover (rubber, plastic, or ?) on the bottom and top of your MacBookPro 16"?

Any cover must respect the airways that cool the Macbook Pro . One sure way to kill a notebook mac is the cut off its cooling air. I've seen some cover that, in attempting to be more 'generic" in their fit, ultimately block air intakes or exhausts passages and vents. These are the vent locations on a 16-inch Macbook Pro:

The hinge area is the exhaust outlet. None of the areas can be blocked.

I've seen Mac notebooks back to the the PowerBook G4 days where dirt and dust got between a flexible cover and the computer's metal case. Left for a long time, there was eventually some scuffing on the anodized aluminum case that was not very pretty. As the anodized finish can only be applied in an industrial setting, you can't fix damage like that without replacing a part. The display assembly alone for a Retina Macbook Pro can cost US$500-600 to rpealce parts and labor. Want to risk that?

They look good for protection from scratches and bumps, but can they do harm, such as heating or pressure?

FWIW, I would not use a hard case/cover on my Mac for the reasons you mentioned. The Mac already has a hard case. You can use a sleeve or computer backpack to protect it while traveling/moving the computer.

Nope. Too many of them are not conducive to proper cooling and I'd just as soon not try several to find one that might work. Normal careful treatment is all that's needed..

If you use a cover that is apple certified, you can use it without problems

Hi,

I'm using clear plastic hard cover on 15inch MacBook Pro, and it doesn't harm anything.
