add "server=1" to the bitcoin.conf file (and restart bitcoin-qt afterwards) or just dont run the QT and learn to use bitcoind
also... how do i get bitcoind and not just bitcoin-qt? i thought they were the same thing
bitcoind is the server for the bitcoin-qt app (unfortunately NOT included as a seperate executable app in the build of Bitcoin-Qt for Mac OS X)... the bitcoin.conf file is what turns the server on or off via the server=1 command (creates a server with a "listen" port) and CAN be used to set the server on with Mac OS X ... something in the likes of:
rpcuser=bitcoinrpc (or can be anything you want)
password= (can be anything you want)
rpcport=8332 (or whatever port you specify here, use default 8332 for running pypool on top)
port=8333 (for listen function)
rpcconnect=127.0.0.1 (internal loop-back address)
testnet=0 (to turn off testnet testing service)
listen=1
server=1
rpcallowip=your miner(s) ip here or use the * for a range (ie 192.168.1.* for whole block range of 192.168.1.1-255)
allowreceivebyip=1
The bitcoind app can be manually built on Mac OS X if you read the make file... but then you can't run the GUI, so just stick with the Qt app...
That should get you started.
Next run python 'run_pypool.py' command in terminal to execute the app (with select flags for whatever you want to manually set). If it gives you a fuss you can cd into the containing folder and/or cd and drag the file to the terminal window and press enter...
Don't forget to tip me.
Thanks
