RPC Miner Help

[Lysander]

Hello everyone. This may seem like a stupid question but I'm obviously new. I downloaded RPC Miner for Mac and I followed the instructions to start mining. When I started, I realized that it wasn't working because I had input the IP address wrong. When I go back to the setup wizard to correct this, it has the flawed IP already listed and it will not allow me to move my cursor or backspace to correct the typo. Is there any way to clear this information from the the Terminal's memory to input it correctly? Thank you.
