I'm typing from my Edge iPhone because my MacBook is frozen. I tried to open an avi file and it froze Quicktime. Then then i tried to force quit and that wouldnt work. So i opened up the terminal and did the killall command to try and stop quicktime That froze the computer. But the spining wheel is there hapilly. So my question is. Will it fix itself or do i have to force shut down? I don't really want to do the force shut down because it's bad for it.. help me macro experts! Please!
