Hello, I have a 13" Mid 2013 MBA base model on OSX 10.8.5 that seems to be acting up every time i use safari (rainbow beach ball). It'll pop up every minute or so while i'm using safari and freezes if i play a game on Facebook. While typing this thread there's a slight delay where i'll type the words, but they wont appear until a second later. I have no extensions installed on safari. I've closed all my apps and only have 3 or 4 tabs open. The laptop isn't hot underneath, so it can't be a heat issue. Could the integrated GPU (HD 5000) be the issue in that it isn't powerful enough for heavy flash/shockwave website?
