Well, the first issue that I faced was the fact that the Application Support folder was by default hidden, so it did not show up in the finder search. (instructions on how to show hidden files: http://ianlunn.co.uk/articles/quickly-showhide-hidden-files-mac-os-x-mavericks/)
The second issue was that TextEdit by default saves the documents created as Rich Text documents - if you try changing it to a .conf document, it causes the wallet to bring up the error of “the application closed unexpectedly”. What you need to do is go to the preferences of TextEdit and in the New Document tab select Plain Text. That can then be renamed to a .conf file and it works just fine.
I realise these two problems are very likely caused just by my lack of technical knowledge, but it did cause a lot of irritation on the way though.
