Why can my iMac not handle the new version of itunes? It's driving me mad! I need to use the imac (500mhz with 640mb Ram) as it has by far the best airport reception but its unbearable to use itunes. Activity monitor says that itunes is using between 60 and 86% of CPU. It can't even cope with itunes, safari & Messenger at the same time. Terrible performance. Surely this isn't right?!? This is after a clean install of Panther and updating everything. Anyone else had this problem or shall I dig out my 9.1 cd?
