Safari2Yahoo 01182006 for Mac can be downloaded from our website for free. The software lies within System Tools, more precisely General. This free Mac application was originally created by Phillip Moore.
From the developer:
Safari2Yahoo is a simple AppleScript application that is workaround for a bug in Safari that doesn't allow you to change the search engine from Google to something else. Safari2Yahoo creates a copy of Safari.app named SafariYahoo.app and modifies the files in the bundle such that the SafariYahoo.app will use Yahoo! search instead of Google search. For now it only uses the main yahoo.com search and not any country specific search.
