Don, It sounds like the FTDI driver is not installed on your MacBook. You need to download and install the latest driver for Mac OS X (V 2.2.18).

The only two ports I see are "Bluetooth-PDA-Sync" and "Bluetooth-Modem". The first gets "KAT500 is not responding" error message from the KAT Utility. The second gets a "Unable to open serial port" error message. Any helpful hints would be greatly appreciated. Thanks and 73, Don NA6Z ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
