My Macbook has vertical colored lines on part of the screen. Rebooting it did not help.

I tried taking a screenshot and the lines are not on the screenshot.

Hi!

Can you tell me the exact version of OS X you are currently running, please?

Click the Apple logo in the menu bar at the top left of the screen

Select "About This Mac"

In the window that opens, look for the "Version" information. Please let me know what it says.

Thanks,

John

The lines are covering the left corner of the screen. It is a Macbook and quite new.

I cannot wait any longer...think it is a cracked screen. Please do not charge me. I do not want a subscription...I do not think it is a software problem. I thought that you were to contact me by email and I was watching that.

Expert:  John T. F. replied 1 year ago.

Yes, I am.

Restart your Mac

As soon as you hear the Startup chime, press and hold the SHIFT key

Continue to hold the Shift key until you see the Apple logo and progress indicator.

Then, let go of the Shift key and let it boot to the Desktop (it may take longer than usual so please be patient).

Do you still see the lines?

John
