I have a macbook snow leopard....i bought second hand in the online applestore .I started the computer the 6 Aug 2009 and i set up the right date and time . After few week i observe that the mac shows on the display the right date but the ''internal'' date is always the same day : 6 Aug 2009. For example all my old skype message, all my itunes library , all my application, all my imovie projects have the same date :6 Aug 2009.how to fix it?ciao ciao Cristiano
