**Install Karabiner Elements**
  
Select Virtual Keyboard | Keyboard Type | ISO
Note: ISO is the European keyboard

Additionally, I like to swap Command and Option keys as this fits the Logitech Windows keyboard I am using.

**Swap Command and Option Keys**

Keyboard | Keyboard Shortcuts | Modifier Keys
Select Keyboard (karabiner Driver Kit)
Now you can swap Option and Command keys

Note: ISO is the correct keyboard type if you are using a European keyboard.
