Hi Chris, this sounds really strange! If your Mac upgraded the os, you definitely would have had to start the upgrading process by hand, I also think you would have had to authenticate using your password. In any case, the new Mac Os is 10.6.3. Maybe you should just cjheck for software updates again, maybe it'll come up this time!
