Nor will any simple rag do
Whatever You Do, Don’t Clean Apple’s Fanciest Display With Water!
If you decide to kit out your new Mac Pro with Apple’s ludicrous 32-inch Retina 6K Pro Display XDR with “nano-texture glass” for a $5,999 grand total that is as much as an entry level Mac Pro itself, there’s something you should know before you unpack it: do not lose the polishing cloth. According to Apple, it is the only cloth that should ever touch the display.
A support document for the Pro Display XDR posted on Apple’s website cautions strongly against using just any old rag on the display or, god forbid, water warning: “Don’t add water or use other liquids to clean the nano-texture glass. Never use any other cloths to clean the nano-texture glass.”
If you lose the cloth, you can order another through Apple. Or you could try a normal cloth, which might work just fine! That is, if you’re willing to bet six grand on that hunch.
