No matter how I change my settings, my iMac Retina's monitor switches over to the screensaver after only one minute of inactivity. Quite a bother when I'm trying to read something. This continued after I upped to OS 10.12.6. I've zapped PRAM and repaired permissions and this, that, and the other but it won't stop doing this. I've looked on the web for answers but can't find any others suffering this malady. Ideas?

  • What do the commands defaults read com.apple.screensaver idleTime and defaults -currentHost read com.apple.screensaver idleTime return? – grg Aug 29 '17 at 16:36
  • have you tried setting it to never come on? – jmh Aug 29 '17 at 18:46
