I need to upgrade my browsers BUT first must upgrade my OS -- I was told by Apple geniuses I myself can actually upgrade BUT I suggested to them, "what happens if I'm confronted with a glitch or a problem I cannot solve?" -- They suggested they can upgrade for me -- I was also told the charge for this service was "nothing" -- Does all this sound correct to you? -- I want to make an appointment with the MAC people but I want to ensure I spoke with someone who relayed their "Apple policy" to me and NOT some personal agenda of a particular salesperson. -- PLEASE ADVISE ME!
