I just started staking yesterday on Mac and you just leave your wallet open, see the top of this page of admins clarification. I haven't recieved anything but I also only have 2k tzc and my computer falls asleep. May set up a wallet on a linux computer later today, but to my understanding we don't have a config file on mac that needs to be edited.
Sorry to disappoint you, it will probably take a month or so to get stakes with only 2K of coins
