Globe and wifi on screen
When I turned on my computer a flashing envelope appeared on the screen so I restarted it pressing command R. This then brought up a screen with a globe where I entered my password for my wifi but nothing has happened since. This happened a few days ago and I took it into the Mac store today. They were able to start it up without this happening and told that there is nothing wrong with my computer. I just got it back home and when I restarted it it is doing it again! I don't know what to do!
