MacBook Pro 2020 running Catalina 10.15.6 does not sleep at night

Question

I've had this issue for about a month. I've done the factory reset and my Mac was fine for a week but is now slowly going back to draining the battery overnight. I've tried everything to fix it and I'm not sure where to go from here. I'm sure if I go to Apple they will tell me it's some sort of bug.

Before I did the factory reset it would run literally all night doing the same set of actions over and over, resulting in a large battery drain - here are the results from that ((help) 2020 MacPro battery draining overnight).

Some additional information:

1. My Bluetooth is always off
2. I close all apps at night
3. I've gone to Activity Monitor to find out what is preventing sleep but it's just the OS systems, none of the (very few) apps I have installed.

I'm not too flash with computers so I will just post the terminal log results that my Mac repeats all throughout the night. Please help!

Answer 1

Buried in the log is

Wake reason: EC.RTC (Alarm)

This is the real time clock and can be triggered by an alarm on the Mac. I would check if you have anything set to wake the Mac up - backups with TimeMachine, other programs that check things like messages / mail even power saving / sleep options.

It could be worth resetting the PRAM/NVRAM and SMC to clear any corrupt settings.

You could try booting into safe mode and see if it still behaves that way.

Try setting the disks to sleep when possible

Check if Bluetooth devices can wake the computer - if possible try this as NO (maybe an issue if you have a BT keyboard and mouse - not that I ever did that - no not me !)

Are you sharing disks / printers / music? Try turning them off.

Sorry it's a bit long - try the SMC reset first.

Answer 2

To manually initiate a sleep on the mac and override 'Preventing Sleep' applications run

pmset sleepnow

in the terminal

(you may find something in man pmset that can alter the settings, I performed a quick look but couldn't find anything)
