Ford, in which directory did you install your AF5 into? How did you do the installation?
Go ahead and download and install the 5.1.0.5 patch as per the instruction in the link I gave earlier
You seem to be missing the adapter cable for JR/Spektrum as per the attached photo. You will need to purchase this adapter cable to use your DX7. Follow the cable connection diagram I posted
Just an additional note: Before installing the main program and patch on Mac OSX, users must have Administrator rights on the computer. To set Administrator rights in the Mac OS follow these steps:
1) From the Apple Menu select “System Preferences...”
2) Click the “Users” icon
3) Double-click on the user’s name to edit the user’s settings
4) Click the “Password” tab
5) Check the “Allow user to administer this computer” box. Disable any "guest" account.
6) Click “OK” Log out and Log back in (from the Apple menu) to make the changes take effect.
Note Only a user with administration privileges can make the changes listed above.
Here's a useful link on how to set the admin rights
