Hi guys, long story short, havent had a mac since the LC3 years ago. Worked at Microsoft, was PC for ever, now i purchased an iMac and was wondering a couple things: 1. I only have an internal 500gb sata HD on my PC, best way to clone data? 2. Regarding the HD how can I use it as a back up, do I need an exernal enclosure first? I would assume but what about power etc. 3. What do I need app wise to make it more effidcient. Does Mountain Lion come with any aps from Ilife or is it a seperate purchase. Seller said it doesnt have ilife, but what about iphoto etc? 4. Lastly, and I cant find this answer, but is the graphics card at all upgradeable? Its a 12,2 model and i just dont know where to look online. Thanks everyone!
