Hey guys, I'm using the new Macbook Air- Haswell i5/8/256 It was lightning fast on Mountain Lion. I only saw the infamous apple beach ball once from July up to this month... and that too an app was not responding and that's why. But since I upgraded to Mavericks, I have been seeing it on a daily basis. Even when just browsing on safari. Not that it's that big of a deal, but it just seems like there are more 'pauses' when using the Air. Anyone else experiencing a similar problem?
