For the last month, my Mac has refused to go to sleep – even when commanding it to do so. The screen goes black, but the computer is still on.
I have checked Apple's support page and made sure that the Energy Saver settings are correct. I've also checked under the Energy tab in Activity Monitor and can't find anything that is
Preventing Sleep. I have followed the instructions to reset the SMC and NVRAM.
In Terminal, when I do
pmset -g assertions I get these results:

PreventSystemSleep is active
1 for some reason.
- I had the old Caffeine app installed and made sure it wasn't active and then uninstalled the application. I'm not sure how to check if the system is "caffeinated", but I don't think
- I've tried shutting down my other network devices while troubleshooting and don't believe that there is some network service causing the problem.
Is there a way to check what's keeping
PreventSystemSleep active? Is there a way to disable it?
