Hello, after the latest update (Catalina version 10.15.4 (19E287)), my iMac won't go to sleep. If I select "sleep", the screen goes black for a couple of seconds and then it turns back on.
I checked all the energy settings and they are correct, I followed also the steps for the SMC reset.
No luck.
Any ideas what prevents the computer from sleeping?
iMac (Retina 5K, 27-inch, 2017)
Thank you

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

Open Activity Monitor in Utilities>Energy tab, sort on Preventing Sleep, any listed?
No, they are NO. Mail is the only one as YES but it's under App Nap...
Quit Mail & see if it still happens.
Tried quitting Mail, but it didn't do anything.
I'm going to try to turn the computer off, unplug, wait, plug, turn on one more time because I can't think of anything.
Thanks for your help anyway
iMac screen goes to sleep and wakes up right away
