My Imac keeps saying my startup disc is full & I need to delete things to make more space. I have tried deleting docs & downloads I know I don't need, but I don't know what else I can delete. I am afraid of deleting important things that may effect what I need. I can't even download the new itunes or pictures because of the lack of space.
iMac, Mac OS X (10.7.5)
