I did a software update and downloaded a superdrive update. Now every time I restart i get a message that i don't need this update and at this point i just can't find where this file is to delete it. I don't want to restart every time and get this message. I thought I had a superdrive. I can burn dvds. Its a macbook 2.0 with a dvd/cd burner a MATSHITA DVD-R UJ-857:.
