Thanks for the quick reply. I totally missed the tilde.
Is there any way to get into that directory with the finder? I can't see it in my home directory.
I believe that OSX hides the Library folder by default. I think you can run:
chflags nohidden ~/Library/
From a terminal command line to "un-hide" it. You may need to restart your finder after running that command.
How can I open that file with TextEdit?
While in TextEdit, if you create a new file...
Click "Save" and you should be prompted for a filename and location.
In the "Save As:" text entry field, type the tilde character and it should pop up with a "Go to the folder:" text entry.
Type in the path: ~/Library/Application Support/Bitcoin and click "Go".
I'm not sure how to open the file if you've already created it and still have the folder hidden. I suppose you could run it from a command line.
And the main follow-up question: how do I run Bitcoin from the command line? I mean bitcoind, which I believe comes installed with the Bitcoin app. I can't find this file anywhere.
I don't think there is a bitcoind for OSX. Or at least there wasn't the last time I looked, but it's been almost a year.
