Hi, Just joined this forum to find information regarding Macbooks and so far I have found lots of good info. I am new to Macbooks and I got my Macbook pro yesterday and its a cool change from a PC. I have a few questions that I could not find when I searched so I hope someone here could help answering them. 1. The Macintosh HD icon that appears in the top right corner, is that a default setting? I checked some threads here and looked the screen shots and it seems that lots of others have this same icon on the screen, so I am assuming that this is a default setting straight out of the box. 2. Could someone direct me to a thread that guides me into what I should do when I first receive my Macbook pro? I read somewhere that I should turn on my firewall, so I already did that. Any other things I should install, or change on the default settings. 3. What is a Leapord? Panther? I know its a big cat but I see this term being used a lot regards to the OS. What OS do I have? and what are the differences? Thanks in advance.
