Hey Guys, Just got my first MAC (Retina 15 inch 2.4/16GB) and I must say I'm pretty disappointed so far. The thing is brand new and the UI is already sluggish and choppy. Compared it to a friend's old MBP with less than half the specs and his is butter smooth. I did some research and this seems to be an issue with many retina macbooks. There's an issue with the intel 4000 hard drive. (https://discussions.apple.com/thread/4214887?start=0&tstart=0) This morning I wake up and it's way worse than I thought, the Apple Mail has a weird blue graph and when I scroll the graph goes fuzzy but doesn't show the mail. Can anyone tell if this is a hardware or software issue? So far the problem did not persist but I fear it might be back soon. I just hope I don't have a malfunctioned retina MBP.
