No luck. Updated the firmware of the Sesto Sensor 2, but still the same error when trying to connect to Mac.
Jasem, the install you did recently, was that using a Mac?
No that was on StellarMate. Then it is probably a MacOS USB serial-port issue that was reported in the forum. Maybe some drivers need to be installed for the serial port to work?
Indeed, Linux is working well. It is an issue on the Mac.
Latest serial port drivers are installed. Issue is with how MacOS handles these drivers in the never versions of the operating system. Somehow that is not compatible with some devices and their INDI drivers.
