I tried this, but it's not working, nothing happens. I put this in ~/.config/karabiner/karabiner.json, and reloaded launchctl kickstart -k gui/id -u/org.pqrs.karabiner.karabiner_console_user_server But still nothing.

Can confirm: Adding "-Wl -ld_classic" to 'Other Linker Flags' in Target/Runner fixed it. I just wasted three days on this. Thank you so much
