I am looking to sell a 2013 Macbook pro 13, so was wiping it and giving it a check and i ran the Apple diagnostics and it returned the error "There may be an issue with the display Reference Code: VFD002." I cant see anything wrong with the display with the exception of 1 dead pixel. Apple support chat say that 1 dead pixel would trigger this error. I am a bit skeptical and don't want to mislead any buyer by conveying this information if its not true, but i also don't want to lose too much on it just because it has 1 dead pixel. So opinions/advice?
