When I had a non-unibody Macbook Pro, I would actually doodle with a dry-erase marker directly onto my (glass) screen. This was handy for making small annotations as I was pondering designs, PCB layouts, etc. Unfortunately for my screen-doodling habit, new MacBooks have some kind of coating (AR? Oleophobic?) that causes the marker's fluid to bead up, ruining the effect.
> Unfortunately for my screen-doodling habit, new MacBooks have some kind of coating (AR? Oleophobic?) that causes the marker's fluid to bead up, ruining the effect. I can confirm, my mid 2014 MBP screen is _ruined_. Tried alcohol, screen wipers (which actually made it worse) I am this close to using a detergent (I know I shouldn't). Any suggestions?
Apple is replacing the affected screens for free, I had mine replaced few months back (late 2013, 13" Retnina Macbook Pro).
