This is a list of questions to check our decision making.

Do I want to die on this hill?

  • Pass: This is morally good and if not handled has long term consequences
  • Fail: This if self serving

Am I including everyone?

  • Pass: My ego is not driving this conversation
  • Fail: The people in this conversation will only tell me I'm right and not push back

Keep your Mac from waking by disabling the `InternalPreventSleep` assertion from `com.apple.powermanagement.acwakelinger`

Disable AC Wake lingering in macOS using undocumented pmset features

Every time your Mac wakes from sleep powerd creates an InternalPreventSleep assertion labeled com.apple.powermanagement.acwakelinger with a 45 second timeout. That assertion ensures that even if your Mac needs to wake for 2 seconds to recieve a push notification that it stays on for 45 seconds. Seemingly there's no way to control this. And recent versions of macOS love to wake quite frequently.

Forunately we can disable this. The built in pmset tool has many undocumented features but thankfully it's open source

Cruicially there's an undocumented pmset disabledassertion feature that just makes macOS ignore certain power assertions. To effectively disable acwakelinger we just run this:

$ sudo pmset disableassertion InternalPreventSleep
