Step 1: Do the basic layout configuration

sudo apt install keyboard-configuration
sudo dpkg-reconfigure keyboard-configuration

Pick

MacBook/MacBook Pro

Select your language layout, then hit enter for the following options, or select something other than the default if needed.

Step 2: Make the cmd button work, as it would in MacOS

sudo nano ~/.Xmodmap

Paste this code:

clear control
clear mod4
keycode 105 =
keycode 206 =
keycode 133 = Control_L NoSymbol Control_L
keycode 134 = Control_R NoSymbol Control_R
keycode 37 = Super_L NoSymbol Super_L
add control = Control_L
add control = Control_R
add mod4 = Super_L

Save and close the editor with

ctrl + o
enter
ctrl + x

Then run the file to test it:

xmodmap ~/.Xmodmap

And if it works for you, add it to the system startup:

sudo nano /etc/init.d/custom-startup.sh

Add this code:

#!/bin/bash
xmodmap ~/.Xmodmap

Then save and close the editor. Run:

sudo chmod +x /etc/init.d/custom-startup.sh

Then add it to cron:

crontab -e

Add:

@reboot /etc/init.d/custom-startup.sh

Save and exit, optionally test:

crontab -l

Restart the machine, and see if it the cmd key still works as desired!

Step 3 would be to make the @ button work, but this is still work in progress.
