The article suggests that new Macbook/OS X might be just as bad, but the linked twitter thread (https://twitter.com/Catfish_Man/status/676851988596809728 https://twitter.com/Catfish_Man/status/676851988596809728) makes the situation there sound rather less serious. The issue appears to be slow progress, rather than a total lack of it. (I had the same problem years ago with somebody's spinlocks on Windows running on a single-CPU system; the obvious functions to yield a timeslice will yield only to a thread of equal or higher priority, meaning you can starve a lower-priority thread. But even when this happens, the lower-priority thread does get a timeslice eventually - which sounds like the OS X situation.)
