thin horizontal line on Mac air display

Hey there, dpruneet85,

Thanks for visiting the Apple Support Communities. I understand you've got some concerns over a thin line that goes across the display of your MacBook Air. I'm happy to help!

Based on what you've described, I'd recommend reviewing the information found in the Apple Support article If your Mac display doesn’t look right - Apple Support. If you still need help after that, you'll need to get in touch with Apple Support directly. You can do that via one of the available methods here: Contact Apple Support.

Have a wonderful day.
