My Macbook Air has been having some system crashes lately. I did a fresh reinstall of OS X Yosemite to the latest version, did SMC and PRAM reset. Particularly this computer crashes sometimes when I open the Spotify app or using it. A couple days ago my computer crashed when I was watching a video on consumer reports website. The audio stuttered and the whole system froze and was unresponsive until I had to do a hard shutdown. Heres a report for one of them.
