After installing OS 10.11.4 my Mac becomes sluggish. I check the Activity Monitor and see that the "Keychain Circle Notification" is not responding. Force quitting hangs the entire Mac and I'm forced to do a hard restart. Does anyone have any ideas on this or we just at the mercy of Apple rolling out a fix?
iMac with Retina 5K display, OS X El Capitan (10.11.4)
