Nothing works
Nothing works.
It started off with Messages, it froze, I force quit and when I tried to open it again, it kept looping sending error report after error repot but never opening. I tried fixing this with some of the message boards on here but none worked, then I realized it wasn't just Messages not working, but all of my Apple apps. I can't open System Preferences or the App Store (i wanted to see if I could re-install mavericks) and when I downloaded mavericks from the internet, I couldn't install it, I got an error message saying "this software is not supported on your system."
Basically nothing works and I can't update anything. I have insurance with Best Buy until next year but I'm in school right now and 1. I need my laptop and 2. going to a best buy would be a huge hassle.
MacBook Pro, OS X Mavericks (10.9.1)
