HELP. :'( Sims 3 messed up my Mac Desktop?
okay, so last night I bought sims 3 from origin.com for 31.99 and downloaded it and installed it fine and played it till like 6am. Then this morning I played it for a couple more hours and all of a sudden my Mac just shut off. I had to press the power button to turn it back on. I had to wait like 3 to 5 minutes until I could put my password in, and then when I got to my desktop, my background was gone, it's was the default background, the origin app wasn't responding, and I can't open up minecraft, I can go on google, I can't go on the App Store, anything internet related, it loads for forever and doesn't do anything. I can open up folders, pictures, notepad all fine but nothing internet related! WHAT IS GOING ON??! :(
