Your explanation completely ignores that, according to the article: 1. Apple acknowledges the bug. 2. Is working on a fix. 3. The bug affects other apps.Yes. What I originally quoted.
" OS X 10.9.5 was crashing after updating to Spotify version 1.0.15.133."
It doesn't say that Spotify was crashing after updating OS X, so it's obviously something Spotify changed in their code. (unless MR is just doing a ****** job reporting the story and has the details wrong.)
So either Spotify and the other affected apps made the exact same changes to their software, causing kernel panics, or it's a known bug that Apple will eventually fix. Based on evidence presented, I'm more inclined to believe Apple knows about the bug and will fix it.
