Remap US key next to enter to enter in MacOS

The Czech keyboard layout on a physical US Mac keyboard has some keys which are pretty much useless. For example the key | aka \ next to the enter is actually also available on tilde key next to left shift in Czech layout and since I am used to wide enter key I end up pressing it when I want to hit enter. It renders to a weird “double tilde” character which I never use anyway. Well, an easy help. This can be remapped pretty easily:

hidutil property --set '{"UserKeyMapping":
    [{"HIDKeyboardModifierMappingSrc":0x700000031,
      "HIDKeyboardModifierMappingDst":0x700000058}]
}'

That’s all, really. No need to restart anything, but to do this after each boot a property list for launcher must be created. Here it is:

cat << EOF | sudo tee -a /Library/LaunchDaemons/org.custom.keyboard-remap.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>org.custom.keyboard-remap</string>
    <key>ProgramArguments</key>
    <array>
      <string>/usr/bin/hidutil</string>
      <string>property</string>
      <string>--set</string>
      <string>{"UserKeyMapping": [{"HIDKeyboardModifierMappingSrc":0x700000031, "HIDKeyboardModifierMappingDst":0x700000058}] }</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <false/>
  </dict>
</plist>
EOF
sudo launchctl load -w /Library/LaunchDaemons/org.custom.keyboard-remap.plist

Worry do not, this is still a Linux blog. I just ended up using MacOS on desktop a bit more lately, I still run Linux remote shells :-)
