I'm trying to communicate with the new Bitcoin-Qt -server via a command line on Mac. I run ./Bitcoin-Qt -server, the application starts, but my terminal window is stuck on an empty line (no matter what I type in, there is no response). Only when I quit Bitcoin am I able to run any commands, but then I can't communicate with Bitcoin, because it is already off.
How do I start Bitcoin-Qt -server on Mac and control it through command line?
