SOLVED : The INDI drivers are OK. But the device drivers were not.
I solved my problems by updating the drivers of the focuser and of the scope.
Here is what I did :
1/ To update the MicroTouch focuser driver to 64-bit :
Go to
www.silabs.com/developers/usb-to-uart-br...rivers?tab=downloads
and download the CP210x VCP Mac OSX Driver
The folder macOS_VCP_Driver contains the 64-bit driver SiLabsUSBDriverDisk.dmg
That’s it !
2: To update the Celestron driver is more tricky :
The forum CloudyNights.com gave the answer (
www.cloudynights.com/topic/584654-updati...estron#entry11950805) and especially the contribution of johnnydecimal, on 22 May 2021 - 07:24 AM, said
Apparently one must run the CFM app from the Terminal and not from the Finder
johnnydecimal explains this very well. A HUGE thanks to him !
Edited 22 Aug 2022:
The Prolific driver has to be updated too
