Macbook Air not shutting down all the way

[linuxgrrl]

Hi,
I recently installed Manjaro XFCE on a 2013 Macbook Air. When I shut it down using the menu, I don’t think it’s shutting all the way down. If I put it in a bag, it stays hot, the battery depletes, and it wakes back up with a couple of key presses.
I did a little research and some people suggest editing /etc/default/grub. See here:

Manjaro won't completely shut/power off

Hello All, My PC won’t shut/power off completely unless I manually press the power button. It shuts down using the terminal, but not with the mouse. My machine is a Lenovo ideacentre 200-01IBW. Thank you!

However, the relevant line in my grub file does not look like what these other users are describing, so I don’t want to just randomly mess with it.
Here is the possibly relevant line. Should I edit it, or perhaps do something else entirely?

GRUB_CMDLINE_LINUX_DEFAULT=“quiet apparmor=1 security=apparmor resume=UUID=d73d5c61-aa02-43a7-8aa5-484b6088075e udev.log_priority=3”

From the solution, simply add acpi=force apm=power_off to your own grub command line.

GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor resume=UUID=d73d5c61-aa02-43a7-8aa5-484b6088075e udev.log_priority=3 acpi=force apm=power_off"

On all computer I touch I also add the splash parameter to go with the quiet parameter, so instead of a black screen (quiet hides the console boot process), it will, on most computers, show the motherboard/manufacturer logo during boot, so for your GRUB command line it would be

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor resume=UUID=d73d5c61-aa02-43a7-8aa5-484b6088075e udev.log_priority=3 acpi=force apm=power_off"

And don’t forget to sudo update-grub from a terminal for the changes to take effect.

//EDIT: edited post as I copied your line, but it seems you had wrong quote characters… weird.
yours: “
mine: "

Thank you - yes, I followed the instructions and it seems to be shutting all the way down! Much appreciated.
