I downloaded the osx-cdtweaks-v9.zip file, unzip everything into game folder. But when I ran the setup-cdtweaks.command, the terminal just showed me ./setup-cdtweaks was killed right after it was started. Like this:
~/Library/Application Support/Steam/steamapps/common/Baldur's Gate II Enhanced Edition/setup-cdtweaks.command: line 3: 19080 Killed: 9 ./setup-cdtweaks
