I was trying to get or request a registration number for some software I had on my macbook pro, & it offered me to send a request for a number, I clicked yes, & mail opened up. But I realized this may not work as I do not have an internet connection to my mac laptop right now, so I tried to close both the software & mail. I could not, the red button in the top left corner was grayed out. So I opened activity monitor & got the software to close. But I could not get mail to quit, I finally forced quit mail & it finally shut down. What happened? I am so afraid my new mac will start to do the freezing alot of people are talking about, I have had it for just a week, I am not sure it was this, I think it may have just been mail trying to access the internet & it got stuck. I checked by opening & closing other apps, & they worked ok. I also notice that sometimes or often when I add an app or move it, I get a windows asking for my administrator password that I made when I first started up my mac for the first time. It makes me give the password before I can do some things. Is this normal?
