New macbook Pro M1 chip waking when asleep with log "SMC.OutboxNotEmpty" wake reason

Thanks, this worked wonders for me (the two pmset commands you describe + disable "Wake for network access"). I compared having the "Optimised battery charging" turned on and off under Battery settings in System Preferences but did not notice any difference in battery usage when in sleep mode btw the two settings

Oh, I needed to do a reboot as well.

So btw 9pm last night and 9am this morning I did not have any DarkWake's - well, apart from one at 7am:

"DarkWake from Deep Idle [CDN] : due to SMC.OutboxNotEmpty smc.70070000 wifibt wlan/ Using BATT (Charge:72%) 15 secs"

Not sure how to get rid of this but unless it starts to run very frequently I will just ignore it and consider the problem solved.

Before this fix I lost 20% battery power over a 12h period due to constant DarkWake's and after only about 1% for same duration which I find acceptable.

Running on M1 Macbook Air with no peripherals connected.

You're right. Apple does not explicitly provide users with access to turn off darkwake. At present, we can only use this way to minimize the occurrence of darkwake. I have feedbacked to Apple many times, but it has not been effectively solved. The existence of darkwake will lead to many problems. I hope apple can pay attention to it, either provide the function of turning off darkwake, or fix the issues of darkwake.

Is there any other reason for this? I have no devices connected to the laptop, and no charger plugged in. Just the laptop alone. It keeps waking up every and sleeping after few seconds.

Two different reasons:

• NUB.SPMISw3IRQ nub-spmi.0x02
• SMC.OutboxNotEmpty

Why does this happen?

I have exactly same issue, these are generated in my logs every few seconds when my Macbook Air M1 is sleeping. Also two different reasons NUB.SPMISw3IRQ and SMC.OutboxNotEmpty.

This results in battery drain about 2-3 % for 7-8 hours of sleeping. Very annoying.

I have the same problem. It drains the battery over the night constantly

Thank you for valuable information and solution. Do you think this might be a hardware problem or a faulty macbook unit?

Or is this considered to be a case for every each of a M1 macbook?

I do not mind that my macbook wakes up from sleep few times a night. But what bothers me is the rate of waking up because of these two reasons (OutboxNotEmpty and the other one). It happends like every few seconds or minutes.

Thanks

Thank you for your assistance here. Just two quick points

1. Has a Radar been filed about this issue? If not, one should be filed so that this can be addressed in a future OS update
2. Can you explain what those commands do, and how to reverse those changes:

sudo pmset -a tcpkeepalive 0
sudo pmset -a powernap 0

I presume running the following will reverse the changes:

sudo pmset -a tcpkeepalive 1
sudo pmset -a powernap 1

Tried your instruction but not solving the issue. The difference is now the usage of history does not show anything but the battery icon shows it drained battery like before. 

After many conversations with Apple support and giving the laptop to Macforum, they promised me to refund the laptop but again they called me saying it is not possible to refund it and I have to send the laptop to another service center !!!.

This is the last time I bought something directly from Apple. Very disappointed support.



After several conversations with apple support they sent the computer to a repair center in Czchek and they returned the laptop after one day.I have been told the issue has been resolved. Not only the issue has not been solved, Now I have two scratches on the body on my new laptop.

Disappointed service from apple. Never buy apple products directly from Apple.

Same issue here. I've got a new MacBook Air M1. I'm loosing 4-5% during 24h in sleepmode. It may not as much drain as some other users are experiencing, but it is still annoying to me. I've talked to my apple dealer. He said, that there should be no drain at all. No matter the chipset.

Same here with my MacBook Pro 13 inch. Posted in the german support forum (https://communities.apple.com/de/thread/252534932), but I don't think anything will happen. Seems, that not all users on M1 have this problem or maybe don't realize it and as someone already said: Apple is only reacting when a massive amount of users are affected.

This totally worked for me! Thanks so much!

However, when I typed the first command, a warning was displayed, so I'm not entirely sure if it was "accepted" by the terminal.

Also, I kept the optimized battery charging enabled, and it hasn't affected my battery so far. Out of curiosity, why did you suggest disabling it?

The first command may cause the "find my mac" function to be inaccurate, because apple cannot get your location during sleep.

Actually you can use the command "pmset -g custom" to see if the command you typed is success.

The optimized battery charging function will lead to a wake request, which means that your Mac will be waked up to do some maintenance work during sleep.

Same issue and macos 11.2 beta2 doesn't fix the problem. Really disappointed for apple.

There is no Power Nap option anymore for M1 Chips based macs.
