After installing upgrade tp lion I am unable to launch safari.
A few months ago I upgraded my iMac to snowleopard via a disk. Then bought upgrade tp lion on line. installed lion and now I can't launch safari .
iMac, Mac OS X (10.7.4)
Do a Get Info on Safari in the Finder, what version is it?
Do you have any 3rd party Safari Extensions installed?
Open Console in Utilities & see if there are any clues or repeating messages when trying to open Safari.
