My mac is stuck on the white startup screen!
So, my sister was fooling around on my laptop, and somehow managed to change the color display. After that, system preferences became unresponsive, so I forced quit. After that, it would be unresponsive every time I opened it. My other apps like Safari and Chrome would shut down within a few seconds of opening them. So, I tried restarting. When I tried to turn it back on, it got stuck on the white startup screen with the apple logo in the center. It's still stuck that way! It's a school laptop, and winter break ends soon. I need this fixed ASAP, thanks!
