I have installed bitcoin core on mac and accessed the config file from the preferences tab on the bitcoin-qt.

Now, I have started testnet on it by the below settings.


I was able to run it properly. so I thought of accessing the RPC from other systems, so I have assigned a public IP to it and in the config file, I have mentioned


Now, I tried starting qt on my mac but unable to start it as it throws Invalid -rpcallowip subnet specification and I could not open the preferences tab and then open the configuration file.

I have tried to access the folder directly by going to the location '~/Library/Application Support/Bitcoin/' but there was no folder named Bitcoin in my mac.

Is there any other location, where it would be?

I have searched the entire system using bitcoin.conf but found no results.

can anyone help me on this?

    How did you put that config file (the top snippet) if there was non in that folder? The subnet specification might mean that you need to add a /n suffix to the IP, like This is useful to allow all on local network, like this Oct 3, 2017 at 12:53

    Hello @StevenRoose : thanks for the reply. I've done it from bitcoin qt where there is an option to open configuration file from preferences tab.
