Apple Warns Retina Display MacBook Pro Users Not To Use Palm Rest Covers

A new Apple Knowledge Base article says that leaving palm rest covers or other material on the palm rest surface of your computer could result in damage to the display when you close it.

The memo notes that in order to enable thin design, the clearance between the display and the palm rest area is engineered to tight tolerances. Palm rest covers add thickness that may interfere with the designed resting position of the display, and best practice is to keep the palm rest clear of any material.

Interestingly, this recalls an issue with the then radically slimmed-down Lombard and Pismo editions of the PowerBook G3 Series on the cusp of Y2K, which were plagued with marks on the screen from too-close proximity of keyboard to display when the ‘Books were closed.
