Appleís new FaceTime for Mac beta launch has been marred by an embarrassing security flaw that has been promptly patched server-side. German site MacNotes spotted the flaw and noted that once a user logged into FaceTime for the first time, another user could log into the primary userís account even with the app closed and then restarted. Furthermore, the flaw could allow a malicious user who had access someone elseís Mac to change their password, hack their Apple ID and potentially their Apple Store account too.
