So my friend is missing his Safari application for some reason. He says he deleted it accidentally at some point, I don't know how that's possible lol. I tried passing him the Safari app from my computer, and it loads, but pages are messed up and they render incorrectly. How can he fix this problem? I tell him he needs to run the OS X installer again but he thinks there has to be another way. Plus he doesn't have any OS X recover/installer disks. What can he do?
