I installed the latest version of Mac OS on my 2014 iMac. Since I updated with open core I can't do anything anymore I'm stuck in the menu, when I'm in the menu the keyboard and mouse no longer work and when I plug in a keyboard it doesn't work but when I'm in the black menu with the choices at the beginning the mouse and keyboard work. It's when I'm in the menu that it doesn't work
