Help please!!!!
Hi, I tried to clean my Mac, because it was running too slow when I only have been on it for 20 mins. Once I cleaned it, everything was fine. I restart my Mac and an error pop up kept saying finder is not working. I am not able to open anything! Nothing will open, except for my clock and wi-fi. My dad is taking it in tomorrow to the genius bar. I have no warranty anymore since its done. Does anyone know how to fix or know how much it will cost to make it work?
