So I downloaded the 3.1.1 update from Software Update and it prompted me to restart. Problem is, the process gets stuck on the installing updates pane and stays there without restarting. I waited a full 30 minutes and the progress bar never moved. I did a hard shut down and restarted the machine only to discover that Safari refuses to open. Any tips on how I can reinstall Safari? Should I delete the old corrupted Safari before reinstalling? Thanks.
