How do I reset/reinstall Safari without opening it?
Solution 1:
Clear the saved state files so that it doesn't try to reopen those tabs next time it starts.
From Finder:
- Cmd ⌘ N
- Cmd ⌘ Shift ⇧ G
- Copy/paste
~/Library/Saved Application State/com.apple.Safari.savedState
Delete the contents of that folder [data, window_7, windows] not the entire folder, as it's an alias. The next start of Safari should be clean.
