Everything is working fine, I'm just curious how OS X works. Usually on Windows, if you disconnect suddenly during updates, then resume the download, the file may be incomplete or corrupted in some way. Then they are installed, then somewhere along the line something crashes. Is this possible with OS X? I accidently disconnected the ethernet forgettign I was updating, then the system froze a little bit. I closed the update window, plugged in the ethernet, then resumed the download. Is multitasking a normal thing for OS X? Like encoding something while doing something else in the background? My Windows machine would crash for sure.
