Hibernate

https://www.jinx.de/SmartSleep.html

as per this wonderful article.

sudo pmset -a acwake 0
sudo pmset -a lidwake 0
sudo pmset -a ttyskeepawake 0
sudo pmset -a darkwakes 0
sudo pmset -a sleep 0
sudo pmset -a standby 0
sudo pmset -a standbydelay 5
sudo pmset -a hibernatemode 25
sudo pmset -a proximitywake 0

Checks, as per that page

pmset -g | grep hibernatemode #check current mode
pmset -g | grep sleep #shows services, that prevents hibernation
pmset -g assertions #shows triggers to wake up
pmset -g log
  • hibernatemode 0 (standard sleep)
  • hibernatemode 1 (hibernate mode, for pre-2005 portable MacBooks)
  • hibernatemode 3 (safe sleep)
  • hibernatemode 25 (hibernate mode for post-2005 MacBooks)

3 - sleep by default 25 - hibernate on my macbook

As per that page:

# Always use the integrated graphics card while running on battery power
sudo pmset -b gpuswitch 0


# Always use the discrete graphics card while running on battery power
sudo pmset -b gpuswitch 1


# Switch between discrete and integrated graphics cards automatically while running on battery power
sudo pmset -b gpuswitch 2

And if you want to control this setting globally, whether your laptop is plugged in or not, you just need to change pmset -b to pmset -c.

# Always use the integrated graphics card
sudo pmset -a gpuswitch 0


# Always use the discrete graphics card
sudo pmset -a gpuswitch 1


# Automatically switch between discrete and integrated graphics card (this is your laptop's default setting)
sudo pmset -a gpuswitch 2
