So I booted up my MBP today, and to my surprise, my desktop icons were missing. When I tried to click on the desktop, it just started to beachball for all eternity. So I opened up the force quit menu, it wasn't responding. After a relaunch, it did the same thing. After some research, I found that a restart should fix it. No luck. I need help. I can't open any folders. Everything is running sluggish as well. Any ideas?
