I'm running a Macbook Pro retina 13 inches early 2015 with 16 Go of RAM and a 3,1 GHz intel core i7 on OS X El Captain 10.11.1

I keep having some problems with airportd that crashes really often. Sometimes, when I click on the wifi icon on the menu bar, I have the rainbow crash cursor showing up and the menu is not popping up. Then, my mac starts heating up a lot and slowing down and I can hear a loud fan noise. When I check on the activity monitor, the airportd process is taking a huge amount a RAM and 100 % of the processor (sometimes more !). Actually, blued is also taking almost 50 % of the processor... I have to kill it manually with the activity monitor for it to get back to normal. But the problem is that happens every 20 minutes in average. I don't know what to do, this is really annoying, I beg for your help !

I keep having this in my system.log :

Dec 13 15:30:21 3wxmr8aqljon9umcd airportd[79737]: SecTaskLoadEntitlements failed error=22

I have that after I kill airportd after a crash:

Do the update to 10.11.2 first and see if that helps.

  • Well, it have been happening before upgrading to OSX 10.11.1 but I'll try to update to 10.11.2, thanks. – tourdetour Dec 13 '15 at 15:32
  • Oky, the update is done. It's kindda better, but I still get some crashes when there is a heavy charge on the network usage... – tourdetour Dec 22 '15 at 16:45
