had made my mind up to buy a pro Mac - so a real investment -but reading some reviews I have found that their latest system is having web connection issues. I saw some complaints about failing connections and others who couldn't connect at all. Has anyone had trouble connecting with the latest Yosemite system? The thought of raiding my savings and not having the web and emails horrifies me. I wanted to purchase from Apple shop as it is the only way to get the one to one lessons for £70.and believe me I will need those! Otherwise I would buy from John Lewis who would probably let me take it back if it fails. I would welcome any advice on my deliberation. If you can offer any help I would be grateful.
