I have my preferences set so the screen locks 1 minute after sleep or after the screensaver goes up. This used to work until I upgraded to El Cap. Now no matter how long after the screensaver has gone up I never get asked my password, the lock screen just does not happen. Any idea why?

  • Same problem in Yosemite. Same resolution (rebooting). – Josh Sanford Mar 14 '17 at 16:07

I can report the problem seems to have resolved 'naturally' after a reboot. It is unclear why though.

  • I have this issue in 2017 on High Sierra 10.13 (17A405). Rebooting "fixed" it for me. But this is a serious security issue and it must not happen, ever :/ – Dalibor Filus Oct 30 '17 at 13:14
