How can I use Torify for an App on OS X
Tell your command where your myapp.app resides

You need to provide the open command an absolute or relative path to the application, unless the executable is already within your $PATH, or you change your working directory to the location in the filesystem where your myapp.app is (in my examples, myapp.app is the Applications folder, the home Applications folder, a folder called someotherplace, and the Shared folder, respectively).

 open /Applications/myapp.app
 open ~/Applications/myapp.app
 open ../someotherplace/myapp.app
 cd &amp;&amp; cd ../Shared/ &amp;&amp; open myapp.app


You can also type your open command and hit spacebar, and drag your application from anywhere into the Terminal, and the path will be provided.

There is another way

You can execute your executable using its full path  and adding the ampersand.  This will run it in the background so your terminal isn't tied up:

 ./myapp.app/Contents/MacOS/myapp &amp;
 /Applications/myapp.app/Contents/MacOS/myapp &amp;
 cd /Volumes/externaldisk/projects/thisone/myapp.app/Contents/MacOS &amp;&amp; ./myapp &amp;


And interestingly, using this method you can launch as many instances of your app as you have memory to do so.

To use torify with your myapp.app

I'm reasonably sure you need to launch it like this to use torify (assuming your myapp.app is in the /Applications folder):

 torify /Applications/myapp.app/Contents/MacOS/myapp &amp;


or 

 cd /Applications/myapp.app/Contents/MacOS/
 torify myapp &amp;
