I bought a new macbook pro a month ago and have had serious issues with programs freezing. For example, about every thirty minutes or so the song that itunes is playing will stop and the spinning wheel will pop up. This also happens every once in a while with safari. I'll be scrolling through a website and all of a sudden it will freeze and the wheel will show. Each time the wheel comes up it spins for less than a minute and then everything is fine. I have also had this happen during video playback. I've tried restarting multiple times as well as running Onyx and restarting after that. I haven't installed anything out of the ordinary as far as programs go, and I have installed all of apple's updates. Any ideas?
