Hello, I hope it's ok to post it here because it doesn't seem to be an OS specific issue. There is a whole thread in the Catalina Forum and all across the internet there are issues with Mac's not going to sleep.
I have an older (2011) iMac with High Sierra (Apple support called it "vintage machine", thank you for that!).
Until 2 days ago it worked fine, I could click on the Apple symbol and select "sleep" and it worked. Now it doesn't work anymore, the screen turns black but the computer won't sleep.
I tried all the basics (SRC reset, PRM reset, reboot, checked energy saver settings, checked apps in the activity monitor) and ended up running
ApplePushServiceTask 0
UserIsActive 1
PreventUserIdleDisplaySleep 0
PreventSystemSleep 0
ExternalMedia 1
PreventUserIdleSystemSleep 1
NetworkClientActive 1
The external media is my startup disk (my OS is on an external drive but it has been like that for years).
pid 227(cupsd): [0x0000003400118033] 03:58:57 NetworkClientActive named: "org.cups.cupsd"
pid 69(powerd): [0x0000002700088000] 03:59:09 ExternalMedia named: "com.apple.powermanagement.externalmediamounted"
pid 68(com.tclementdev.timemachineedit): [0x000033cc00018930] 00:18:49 PreventUserIdleSystemSleep named: "com.tclementdev.timemachineeditor.backup"
So here is the Time Machine Editor listed - I have this program for years, how can it now prevent the computer from going to sleep?
And maybe somebody can help me understand what this means:
Details: Delay sleep to run activity.
pid 109(hidd): [0x0000213c00098706] 00:00:00 UserIsActive named: "com.apple.iohideventsystem.queue.tickle.4294968268.3"
Timeout will fire in 180 secs Action=TimeoutActionRelease
And last not least we have this one:
Idle sleep preventers: IODisplayWrangler (but I heard this is "normal"?)
My confusion comes from the fact that I haven't changed anything, haven't run any updates, no new apps, nothing.
Anybody who can help me? Thank you.
