<div dir="ltr">Good Morning!<div><br></div><div>Since upgrading many of my machines to 10.11.4 I started running into problems where a handful of them would consistently get incredibly slow and more often than not, users were greeted with a beachball when trying to unlock their screen.</div><div><br></div><div>Via SSH I was able to find out it was the "distnoted" process (part of notification services) that was eating up all the CPU. After killing it, things would immediately go back to normal. I tried OS re-installs, fresh installs + data migrations but the problem kept coming back. I ended up installing a launchd script that will kill distnoted periodically which has worked like a charm so far.</div><div><br></div><div>I still haven't been able to pinpoint the root cause (other than 10.11.4) and apparently I'm not the only one with this problem: <a href="https://discussions.apple.com/thread/7540087">https://discussions.apple.com/thread/7540087</a></div><div><br></div><div>I also heard from someone who reported the bug in January and told me the issue persists in the 10.11.5 beta.</div><div><br></div><div>Has anyone else encountered this problem?</div><div><br></div><div>Regards,</div><div>Andy<br>-- <br><div class="gmail_signature"><div dir="ltr"><p style="color:rgb(0,0,0);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:small;line-height:20px"><font color="#999999">Andy McPherson<br><span style="font-size:12.8px">Systems Administrator</span></font></p><p style="color:rgb(0,0,0);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:small;line-height:20px"><img src="https://mitgsl.mit.edu/sites/all/themes/mit_gsl_theme/logo.png"><br></p><p style="color:rgb(0,0,0);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:small;line-height:20px"><font color="#999999">77 Massachusetts Ave., 14N-308, Cambridge, MA 02139<br><span style="font-size:12.8px"><a href="mailto:andymcp@mit.edu" style="color:rgb(126,87,194)" target="_blank">andymcp@mit.edu</a></span><span style="font-size:12.8px"> | p: 617.253.9776 | f: 617.258.6189</span></font></p></div></div>
