I just installed OS X on my new Macbook Pro, on my 500GB HD installed within it. During the set up process it asked me to add my name and also the name I want it to show up in the finder, as my main home folder. I put in my name, "JohnSmith" but just regretted it. Iono, just did. So once I was using Leopard I opened up System Prefs., went to "Accounts" saw my name on the left pane and right clicked "Advanced Options." In there is gives me the warning that changing these settings could cause damage, so figured I'd ask here if what I did is all good or if any problems might arise. Under Advanced Options I changed my short name from "JohnSmith" to "Smith" And the Home Directory from: /users/johnsmith to... /users/smith I restarted the machine and logged in fine, however figured it was worth asking.
