I have been a longtime windows user and my first Mac is set to arrive tomorrow, hopefully the morning shipment I was just curious if the user structure on a Mac is similar to that of a windows system, ie Administrator, End Users, Guests I have always heard that it is not the best idea to always be logged into your windows system under the Admin account and that it was better to create a second account with admin privledges and login under that. Is the case similar with Mac systems or is it fine to just create one login and use it exclusively for all access? (of course more accounts for other users). Thanks in advance. I am really excited to start playing around in OSX and getting to know the new computer....just want to make sure I do things proper. Any other "config" related advice is more than welcome too.
