Hey,

first thanks a lot for the answer. Great post Sorry about the delay, I have had crazy days.

I reinstalled the OS and haven't tried to fix it like you suggested, because anyway I had done nothing to it so far. I modified the Boot.plist file like you said (with the sudo nano command) and it worked great. But I must ask... why I wasn't able to save my changes when I was opening the file with TextEdit?? When trying to save, I always got a message "you don't have the permissions"... that is why I was going crazy about trying to change the permissions on this file...

Another question... so if I change the owner of a file to root:wheel, what does it do to me? I mean, if I'm logged as MyName (group admin), how root:wheel will affect my permissions?

Thanks again for taking time to answer my newbie questions
