Display got a mark after touching it with finger (not finger marks)

Hi Bob2065,

Welcome to the Apple Support Communities!

We understand that you're seeing a mark on your MacBook display after touching it. In this case, we'd recommend that you first clean your Mac display as outlined here: How to clean your Apple products

If you're unable to clean it, we'd recommend that you contact Apple directly to go over your service options with you. You can reach them here: Contact Apple for support and service

We hope this helps.

Take care!
