Thank you for the help.
I was able to install 0.9.3c, but when I run the export command it never does anything.
I ran this command: wallet_export_keys btsKeyExport.json
Then I used spotlight to search for btsKeyExport.json and it does not exist on my computer.
Is this because the client program will not sync? If so, how can I get it to sync? (It says "Severe network problems" and it does not appear to be making progress.)
