Centauri-Alpha prevents sleep

[fatihayoglu]

Hello all,

My new MPB M5 Pro insists not to go to sleep; the log says
2026-05-10 16:44:25 +0100 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.sysState.Wake(0x70070000) wifibt SMC.OutboxNotEmpty centauri-alpha E_TKO_TCP_DATA ARPT/ Using BATT (Charge:88%) 11 secs

There are hundreds of these however I cannot find an efficient way to find and delete whatever this is.

As a background, when I have bought this machine new, I have installed users from TimeMachine Backup.

BW,
Fatih

Put this command into the Terminal, and it'll tell you what processes are keeping your machine awake:

pmset -g assertions

Nothing unusual however when I put pmset -g log | grep -i "wake from"
There are hundreds of entries for Centauri-alpha as above

am not seeing this issue on my own new M5 pro MBP. does turning off bluetooth help?

someone here might have a fix, but consider calling apple... (just a thought)

 

[fatihayoglu]

So when I turn off WiFi and BT, the laptop actually sleeps pretty well. I’ll wait couple of more hours and enable them to see. I don’t remember if I’ve ever installed Sid Meier Alpha Centauri game in the past, thinking this might be a left over issue 🤷

what about just turning off BT (just to see if that's where the issue is). perhaps check places like system settings>privacy & security>bluetooth, make sure no apps are accessing BT that shouldn't...

 

[fatihayoglu]

ok, so turning off the BT didn't help, but turning off the WiFi did.
Something tries to access the internet when the computer sleeps, need to find that now

 

[fatihayoglu]

Another update, Little Snitch cannot find any connection request yet the computer doesn’t sleep when the WiFi is on

I wish there was a way to be able to search centauri-alpha on my computer 😔

you could try an app like find any file

anyway it's a new mac, so why not call apple & have them sort this out?

 

[fatihayoglu]

They’ll call me tomorrow 🙂

Tried to find the file, centauri-alpha seems to exist in the network.plist files and some google search mentions it relates to N1 chip 🤷‍♂️

Let’s see what Apple says tomorrow

Do you have anything enabled in Sharing?

 

[fatihayoglu]

Nop, nothing is allowed to share. It would be good, if anybody who doesn't see the same log (M5 Pro or Max) can post their terminal pmset settings. Maybe there is something I don't see 🤷‍♂️
