I just updated iPhoto through Software Update, and now my iMac G5 20 inch 2.0Ghz is starting up much slower. When I push the power button, the screen would be blank for about 30 seconds (but the light on the bottom right corner will be on). After the 30 second wait, it will start up as usual. This didn't happen before. Is the computer just getting slower already or did I do something wrong?
