-I have a Meade LX200 8" SMT GPS
-I have a MacBook Pro with Mountain Lion 10.8.3
-I have the cable attached to my USB port on the MAC and to the RS232 jack on the Meade
-The Mac recognizes the USB is plugged in and recognizes when it is unplugged
-The cable setup works when I use it on a PC with other software
-I have Starry Night Pro 6.4.3
-When I open the Telescope Configuration I select "Meade LX200 GPS" and Comm port there is only one option "Bluetooth-PDA-Sync
-When I attempt to connect I get in the connection status: "Communication Error" and in the connection info a statement that says "an error has occured while trying to communicate with the scope.........."
-Any ideas what I should do? Thanks David
