I didn't know what to do and it was right after a software update for iLife 09. It hung there for a little while and I just pressed and held the power button until the laptop turned off. I then restarted the laptop and ever since that instance I seem to have some rainbow spinning disc every now and then and the computer doesn't seem to be as peppy as it was. I've only had the Macbook for several days and I bought it brand new. Any ideas? I'm new to Mac's so please be gentle. LOL!!!
