I just bought a brand new AL iMac 2.4GHz 20" 500GB HD and haven't really loaded anything much on it yet. It is booting up much slower today than yesterday and I don't know why. I have only loaded the Temperature monitor to watch how hot the iMac gets. Other than that, I have started loading my photos into iPhoto, about 2GB so far. Should the temp monitor be slowing the iMac down when booting up? It used to boot up in like 15 seconds, now it is taking about 40 seconds. Not a lot of time, but I don't have any big programs on it yet. Is this computer that sensitive to loading programs or just this temp one? Is there a way to figure out what is causing the new extended amount of time??
