Tried all of these, still wont connect. I need to update my os x and it wont let me.
For months now I've been trying to update my os x, but when I open the app store it says it can't connect to the internet. My computer is connected to the internet, as is obvious from my ability to post this. I tried all of the things apple suggested, even tried updating through terminal. Nothing has worked. I don't really have time to go to the Apple Store to have the 'geniuses' fix it, at least not before this project is due and I keep getting screwed over because certain sites and apps won't communicate properly without me updating.
MacBook Air, OS X Mountain Lion (10.8.5)
