Macbook 16" Doesn't Sleep if Power Nap is Off!

[kaans]

I have this:

pid 330(UserEventAgent): [0x000009bf000b83c1] 00:07:41 BackgroundTask named: "com.apple.routined.persistence.mirroring.backup"

In my pmset -g assertions

On Power Adapter:
1) If I turn off Wi-Fi, it disappears, Macbook sleeps
2) Wi-Fi on, PowerNap off, it's counted on BackgroundTask's - and prevents sleep
3) Wi-Fi on, PowerNap on, it's not counted on BackgroundTask's - Macbook sleeps

Anyone else experience this?

It matters an extreme amount, because with an external monitor, the temps are around 70C at idle, if the Macbook doesn't sleep, it will probably get swollen in some months

I disabled csrutil, then "launchctl unload -w /System/Library/LaunchAgents/com.apple.routined.plist" - also renamed it so after re-enabling csrutil, it doesn't get loaded back

However, now "com.apple.coreduet.sync.update-source-device-identifiers" started blocking sleep as a "BackgroundTask" - it's really frustrating, the device is keen on staying awake with a 70C sustained temp
