So I've had my Mac since February, and just recently it began getting some discoloration when I fire it up. Before it was a grayish/green color, and then I called Mac. They advised to to install to the newest version of Sierra.

It worked! But I go to start it today, and there's a bunch of rainbow swirls on the screen for a solid 2-3 seconds.

Any thoughts?
