Lines Do not appear when drawn

hello.
I am having trouble seeing the lines and vectors I draw in rhino. They are drawn in the model because they can be selected, but they are not visible. Is this a graphics issue? Im using the latest version of Rhino 6 on a macbook pro MacOS Monterrey. Help!

Hi Hussam - has this ever worked on this machine? Does the Display panel have curves checked?
