I'm a current Microsoft Windows user who is about to switch to mac. In my pre-purchase research I've run across the issue of establishing administrator accounts on OS X. I'm a bit confused over the advice given. There's this: "By default, the account created when installing OS X is an Administrator account which has the equivalent of "root" access. It's not secure or necessary to use that account for routine work. While logged in as the administrator, use the "Accounts" System Preference tool to create a non-administrator user account and give it a different password. Then, use the user account for daily tasks." And then there is this: "...set up the first account (the default one you start with) with everything you want to use on a daily basis (like mail etc) that uses already installed software. This account will be an Admin account. When you've got it the way you want it, go into Prefs > Accounts and make a new account called Admin (or whatever) and give it a different password. Check the box on that account that says "allow this user to administer". This is now an Admin account too. It helps to "enable Fast User Switching" at this point also. Log into the new account just to check it's working. Go back to your original account and UN-check that same 'allow this user..' box on your day to day account. This is now no longer an admin account." The second variant, which is from this forum, seems more complicated than the first. What are the advantages to each of these procedures? Do I need to bother with this user account business at all? I plan to buy a non-portable iMac; it will be for home use; I will be its only user (single household....). Thanks for any help on this.
