Applications on macbook pro close waking computer up after 1 hour lunch It's lunch time at work and I put my macbook in screen saver mode by using a hot corner. I return back to wake my computer up, and type in my password to resume work (I have the require password immediately after sleep or screen saver begins option checked.)
I then realise none of my applications are active whatsoever and it looks like a fresh restart has occurred. 

I can confirm that: System Preferences &gt; Security &gt;&gt; General &gt;&gt;&gt; Log out after ... minutes of activity is not checked. 

This is what my pmset -g look like: 

System-wide power settings:
Currently in use:
 standbydelay         10800

Can someone please help me fix this unwanted applications closing after my macbook pro goes to sleep when I return from lunch? 

Additional information:
I can confirm that I also have two external monitors connected to my laptop via mini display ports, as well as an Anker usb host. 

I have macOS High Sierra installed version: 10.13.4 (17E199)

I have a macbook pro Retina, 15 inch Mid 2015.

Not in clamshell mode.
Not sure what's going on with your settings, but I think you will find that caffeinate can prevent this behavior. At a terminal screen, type man caffeinate to learn about the utility. An option that may work for you is this: 


  caffeinate -s 


Alternatively, if you have an application you wish to run while you are away from your Mac, you can use this form: 


  caffeinate -w PID &amp; 


where PID is the process ID of the app that's running (available via Activity Monitor, or ps -la), and &amp; for running in background.
