I booted my computer and it asked me to log in. My computer is not set up that way. That same screen started displaying some weird blinds that went up the screen.
After that, my computer seemed very slow. I tried using Chrome but I kept getting those blinds going up the screen non-stop for no reason. I took a few screenshots but it doesn't display them. So I took a picture of my iMac with my phone:
I had to restart my computer because it was soooo slow and I was barely able to do anything at all. After restarting, my computer went back to normal. But I'm still worried because this has never happened before and I've never had any issues with my year old iMac. Anyone know what's going on?
Edit: There was no sound coming from the iMac either. It said there was no sound output when I looked at preferences.
