Hey everyone. I just recently bought the early 2011 macbook pro 15 inch. Its got 2Ghz i7, 4gb ddr3 ram and 256 vga. I'm loving it. However, only about a week into it, I started experiencing some stuttering during playback with iTunes. What i mean is for example while playing a song it might pause/lag for a second before continuing. This usually happens when Im browsing webpages, or a webpage takes long to respond giving the spinning mouse icon. After that, I usually pause iTunes, and switch the page off. I press play again and there is a small chance it can follow with another skip during the song. Ive had it happen with just iTunes running at one point. Yesterday I updated to the new 10.5.2 iTunes. It stopped the stutter but today it started happening again... What's going on here? Is there something wrong with my macbook? Isn't iTunes supposed to work properly regardless since I have 4 gig ram? how can safari overload it so much that it makes it skip? Music is really important to me. I'm a producer in learning and recently just bought cubase. I don't want this to affect my producing in the future. Everything else is reported to work fine. Please help ! EDIT: I'm running OSX Lion if thats any help. I'm new to mac. Also: Whenever I stop a song playing its usually accompanied by a slight pop.
