hi guys! i'm sorry if this post doesn't fit this category. kindly move it to the appropriate one. anyways, i'm planning on fully reformatting my hd and then install snow leopard again (since i've been experiencing major system and app hiccups ie. adobe products shutting down continuously). can you help me in what i need to backup? like iphoto apps etc., itunes library, candybar icons etc.? i won't be restoring from time machine after i reinstall, i will just back them up using an external drive. please guys anyone with extensive knowledge regarding mac structure, help me with it. thank you so much in advance!
