Can't believe that I have to ask this question, but...

How to I disable the screen saver on my 2014 MacBook Pro, running MacOS Sierra 10.12?

I have a need occasionally to keep the screen display on, but I might not use it for 20 minutes at a time. I want to disable the screen saver, but the button to adjust the time (I presume it has a 'None' option) is disabled.

enter image description here

How can I enable that dropdown, in order to change the 'Start after' time? Or is there somewhere else I should change it?

I know that I can use hot corners to disable screen saver, but that's too hacky - if I forget to put the cursor in the corner, it doesn't do it, and I only know when the screen saver comes on - which is frustrating.


Check out this discussion: Screensaver "start time" option grayed out

  • The system administrator has probably set the screensaver timeout in a user profile. You can't change it without removing the profile, which will probably cause you to lose network access.

  • Check if you have a profile (overriding your personal settings) by Apple > System Preferences > Profiles

  • if you have a profile, one of these files has its settings: ~/Library/Preferences/ByHost/ look for a file with a long name that begins "com.apple.screensaver". There may be two such files. Move the one without the word "slideshow" in the name to the Trash.

It most probably applies to your problem too...

    Thank you! Found that corporate had put a setting in the profile forcing a screenscaver timeout; I can take it up with them now. – PeteCon Feb 13 '17 at 20:41
