I have 2013 MacBook Pro running X 10.9.5.
My GPS is an old GPS 276C which connects perfectly to my Imac but isn't seen by Basecamp on the Macbook.
I am using a Garmin USB cable. The GPS beeps and says USB connected, but Basecamp nor WebUpdater will see the GPS.
I have tried :
>numerous USB cables
>Rebooting MacBook
>Deleted Basecamp and reinstalled
>Took battery out of GPS and reinstalled.
>connected with GPS on and off. etc.
The GPS regularly beeps and says USB Connected, but software does not see it.
Looked for USB drivers for MAC and didn't find any.
Suggestions??
