MBP 16 wakes itself from sleep ...

[HoratioPerdu]

Morning folks,

On three occasions last night I was awoken to the sound of nightly news blaring from my external speakers in the other room ....

It was my Mac deciding it did not want to sleep anymore. Evidently he also decided to press play on YouTube.

It's plugged into an external monitor, and the manual "sleep" button was used each time.

What the hell is going on?

Your external monitor is requesting some space?

(Maybe for some reason it's sending a keyboard command to poll the device? which happens to trigger the play?)

Apparently there is a "user-visible-Weekly Usage Report" that wakes the device periodically, you can see the schedule on System Information > Power - at the very bottom - unlikely, but maybe that woke you up
