Hi all, as of the last week my iMac just won’t go to sleep on its own anymore. I have it set to shut off the display and sleep after 15 minutes, but now if I walk away the screen will still be on even hours later. I’ve checked activity monitor and no processes say they are preventing sleep. I’ve turned off wake for network activity. I think this may have changed after upgrading to 12.2 though I’m not sure. No other real changes since then, though I have updated Onedrive and that is causing other issues (but haven’t heard of any one having this issue).

Any ideas? Why would this be happening, and how do I stop it?
