i have a ibook g4 with 800mhz ppc processor. i saved alot of files to a flash drive two days ago. after that safari was broken. since the apple site says to use update to get safari back i deleted the broken safari.app file in hope of that working. i also got the update safari2.0 package and it will not open, even with pacifist which was recently recommended here. how do i get safari back? it was my favorite browser.
