Professor Moriarty almost did it at Reichenbach Falls, but it took Steve Jobs and his Leopard to finally kill off Sherlock. Apple’s new operating system deletes the abandoned search utility during the installation process.
Sherlock was introduced with System 8.5, but has been dying a lingering death for years, as Apple replaced its functionality with Dashboard Widgets and web utilities became more ubiquitous. Most of its tools had ceased functioning already. I haven’t even launched it in years. In fact, the only way I knew it was gone is that it’s deletion left a question mark behind in my wife’s dock after I installed Leopard.
