The article suggests that new Macbook&#x2F;OS X might be just as bad, but the linked twitter thread (<a href="https:&#x2F;&#x2F;twitter.com&#x2F;Catfish_Man&#x2F;status&#x2F;676851988596809728" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;Catfish_Man&#x2F;status&#x2F;676851988596809728</a>) makes the situation there sound rather less serious. The issue appears to be slow progress, rather than a total lack of it.<p>(I had the same problem years ago with somebody&#x27;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.)
