I recently upgraded my MacBook Pro (~2010 model) to OS 10.12.4 (Sierra)
Starry Night works fine except that I can no longer connect SN to the telescope - an LX200 Classic
I have a Prolific USB to serial converter and have installed the latest driver. The converter shows up in the CONFIGURE in the Communication Port as usbserial. I choose Meade LX200 from the Telescope Type pull down menu.
When I try to connect, I get a Communication Error in the Connection Status. I have also tried using LX 200 Compatible from the Telescope Type pull down menu with the same negative result.
Before upgrading I had no problem connecting with the telescope. I am using the same cables as before.
Do you have any idea why I am unable to connect?
Thanks for your assistance.
