The issue

After fresh install of League of Legends on macOS with case-sensitive APFS volume it's not possible to start League of Legends game, after champion selection the launcher won't open the game client and is stuck with reconnect button.

Solution

Terminal method is probably more reliable as you can see real file names within terminal opposite to Finder which "beautifies" them so you can't be sure what the actual file name is.

Note that League patcher will probably install updates under old filename so it's possible that these steps will need to be taken after every patch until Riot fixes it.

Terminal.app

Open Terminal.app from Applications
Browse to League contents with cd /Applications/League of Legends.app/Contents/LoL/RADS/solutions/lol_game_client_sln/releases/

Set up GPG on macOS

Setup:

brew install gnupg2
gpg --import private.key

brew install pinentry-mac
echo "pinentry-program /usr/local/bin/pinentry-mac" > ~/.gnupg/gpg-agent.conf
killall gpg-agent
