Hello, So my macbook pro is stuck on Feb. 19. It won't save any changes that i make sine that date. For instance if i browse on safari or remove a program from my dock and i restart it, none of the changes i made get saved it all goes back to Feb. 19. Even my history on safari is from Feb. 19. I could save files they stay they don't get deleted when i restart. Im new to macbook so i have no idea were to start.
