I hope I am in the right topic. I am very new to the Mac , just switched over about a month ago. Twice now, I have had the HDD icon rename itself and now the clock and date is failing to keep accurate time and dates . This is a Power Mac G5, dual 1.8 processors, 2 gig ram. Also do not have anti virus or firewall, as I haven't been on the net very much with it. I had a time convincing myself to go with the Airport Extreme, but am finally there. Thanks for any and all help.
