For some reason...it will not let me. I have uninstalled (with the help of AppZapper) Safari 4, as well as the Facebook web application I made. I downloaded the newest Safari direct from www.apple.com/safari. Yes..I DID download the leopard version. But when I try to install it, it tells me that Safari can not be installed, because it requires 10.5.2 or newer. Here's the kicker. I have 10.5.4 installed. THE PLOT THICKENS!!! Anyone know what may be causing this? If you need more info..please let me know. PS. On the apple website, it says that Safari 3.1.2 is the latest version, yet the DMG i downloaded from the same link, only says 3.1.1 (hence the ? in the title). wutupwitdat?
