I ran software update and when the updates were finished downloading it told me to restart the computer. So I clicked restart. When I got to the blue screen with the turning gear it stayed on that screen for a while. Not just a minute or 2, I think at least 10 but possibly even more because I left the room for a while since it seemed to be doing nothing. I came back in the room after a while and the computer was on the desktop. Should I be worried that it took so long to go from the blue screen with the turning gear to get to the desktop? Do you think my updates installed correctly, and would there be any way of knowing if they didn't?
