I'll try to be more clear. The option isn't working for me.
From the article I'm referencing: "Moving your mouse pointer to a hot corner can put your Mac to sleep, depending on your Mission Control settings." Since there is no Put the Mac to sleep hot corner option, just Put Display to Sleep, that the outcome of the Mac going to sleep is undocumented/undesirable.
My sleep schedule is unchecked.
Turn display off after: is set to Never
Hot corner is set to Put display to sleep.
Prevent computer from sleeping automatically when display is off is Checked
Put hard disks to sleep is Unchecked
Wake for network access is Checked
Start up automatically after power failure is Unchecked.
Enable power nap is Unchecked.
Specifically, my problem is that the Mac will go to sleep after some unspecified time after activating the hot corner to put the DISPLAY to sleep. The article I referenced seems to imply that the Put display to sleep hot corner setting can ALSO put the Mac to sleep. This seems like the wrong behavior.
The only way I have been able to prevent the Mac from going to sleep when activating the Put Display to sleep hot corner is by also having a network ping going on in the background.
I'm not looking for a check box to hit, I'm hoping that there is a sysctl to fix this behavior or something else.
My Mac is definitely going to sleep:
% sysctl kern.sleeptime
kern.sleeptime: { sec = 1604272445, usec = 750243 } Sun Nov 1 17:14:05 2020
