Mac won't go to sleep mode

When I log off my desktop on my IMac 24 inch, it will not go to sleep mode when I select sleep, or it takes awhile to go to sleep. How do I fix it so it will go to sleep when I ask it to?

Computer Sleep does not function properly in the latest macOS versions.


Turn on "Prevent automatic sleeping when display is off" and only allow the display to turn off.



Then shut down... for long periods of none use.




FWIW if you are truly interested in what might be preventing Computer Sleep, open your Mac's Activity Monitor, click on the Energy tab, click on the Preventing Sleep Column, look to see what Process is or what Processes are preventing computer sleep.

Have you run Disk Utility's Disk First Aid on all connected drives?


In Disk Utility>View, select Show all Devices, highlight the top left entry.


Run Disk First Aid on all items in the left panel, from top down.


Are you running any VPN, Anti-Virus, or Cleaning apps?
