MacBook's login screen is acting weird.
Hello! My computer's login screen is acting weird. The colours are darker and the cursor is moving slower than usual. It started after I updated my MacBook (Retina, 12-inch, Early 2015) to OS X El Capitan 10.11.6. Is anyone else having this problem? Is there a way to fix it?
