So I upgraded to 10.5 last week, all has been well so far I guess. I run Parallels w/Win2K. I've noticed since the upgrade that Parallels has not worked properly. Well in checking Parallels' website I notice I need an update. Fast forward, installing the update...I am prompted to enter in an Administrator username and password. In the past I've notice the username field is already filled in, but not now!? So I proceed to enter what I know is the admin username and password (my full name and pw), but it doesn't work. So then I proceeded to check the user accounts and it indicates that my user is not an Administrator of this machine. What the heck?! I can't get past the username/password prompt to continue my upgrade. What do you recommend? BTW, I did an 'upgrade' to 10.5, not a fresh install. Thanks for the help!!
