Hello, Earlier today, i used refind to install a copy of ubuntu i had on a dvd. During partitioning, it kind of hung so i force restarted my ma. Nw, i am stuck with a problem i cannot find a solution to on google. When i start my mac, the refind boot menu shows up, with two options. Osx and legacy boot. Unfortunately, it is stuck on legacy boot and i cannot switch to osx and boot it. Arrow keys arent helping. What to do??
