Safari Issues Fix

is the subject of this Apple KBase article. Under certain circumstances, the original build (48) of Apple's new web browser, Safari, may have deleted a symbolic link to a critical file causing problems like being unable to launch Classic mode, print, turn on file sharing, burn CDs or DVDs or use Software Update. The problem is fixed by downloading the latest Safari build (51), trashing the old build (48), installing the new build and launching it. The requisite link is automatically restored during the first launch.
