I have a few rather small questions. 1) I've had my Mac for about 3 weeks, and haven't restarted it for a while. I just did and got a message saying "An item in the Startup Items folder does not have the proper security settings" it says the item is called, StartupItems/CAS I don't know what to press, so I am waiting for someone to help me out! I am also not sure if this is a coincidence, but my name begins with Cas. 2) What does the home key do or how do I make it work. On windows I used to press it all the time, especially in documents and web address bars. Now when I press it, nothing happens. 3) I have had my iMac for over 14 days, and am wondering if they will still exchange it for a cosmetic reason. I noticed it out of the box, there is a smallish black fleck or something on the upper left hand corner, but under the layer of clear plastic. At first I was just so excited to have the new computer, but now I am wondering if I should contact apple. I wish I could just remove it, I am tempted to just keep it because other than that, the computer is perfect. Thanks!!
