The Esatto will not connect on my Mac. It looks like when selecting Esatto, actually the driver for the Sesto Senso 2 is chosen. Is that correct?
 
 

I think the sestosenso2 driver supports the esatto.

With my Sestosenso 2 I find that I have to manually select the serial port for it to work correctly. Otherwise the driver connects to the wrong serial port and kind of hangs, even if I stop INDI completely the indi_sestosenso2 is still there running.

Perhaps it is the same case for the Esatto, I'd suggest setting the serial port manually, save the config. Reboot the system (to ensure that the driver isn't still running) and then see if you can restart INDI.

Ah, that is very helpful. I always have auto search enabled and have experienced some erratic behavior with my SestoSenso before it ‘snapped’ into connection, after which it has been working well. I might just have been lucky then that time and this time is a bit more tricky.
Will try manually connect and see how it works.

Unfortunately this did not work. Also after manually selecting the proper USB-port, the connection could not be established. It looks like it is a problem with the MAC-software/driver, as it does connect properly to a unix (Ubuntu 20.04) machine. This is the message I'm getting. It is looking for a parameter 'SN', which it cannot find. Does anyone have an idea what that means? Unfortunately this did not work.

The driver requested the serial number of the Esatto, and that returned an error. Could be a few things:

1. Firmware on the Esatto is incompatible with the driver.
2. The serial port the driver is attempting to use is not the Esatto serial port.

It's a result of this function in the driver:

github.com/indilib/indi/blob/master/driv...user/sestosenso2.cpp

bool CommandSet::getSerialNumber(char *res) { return sendCmd("{\"req\":{\"get\":{\"SN\":\"\"}}}", "SN", res); }
If it is a firmware issue, the driver download contains the V1.3 firmware: eu.primalucelab.com/info/downloads.html

Thanks Giles.
I have firmware 1.3 on the Esatto. The serial port the driver is trying to connect to is the port of the Esatto. So can't see where this goes wrong. Are the drivers for the Mac version the same as the drivers for Ubuntu? Since everything is working on Ubuntu, could it be a problem specific to the way the drivers are compiled for Mac?
Btw using a Mac M1.

I believe they are the same drivers. But unfortunately, I'm unfamiliar with Mac stuff.

I see you've found the other thread where people are experiencing this same problem. Looks to be Serial driver on the Mac related.

Indeed, and since the problem was identical, I thought the fix would work as well. But unfortunately that's not the case yet. Investigating Silabs drivers on the Mac opens up quite a can of worms....

I have the same problem with a different focuser on Mac.
It will connect with TheSky with the same serial driver but not with Ekos.

Probably there’s something wrong with the Mac port of Ekos?

It starts to look that way indeed. A pity, as one of the benefits of Macs is that driver issues are almost never an issue.

Here's what I used with the MacOSX version of INDI Web Manager:
But this version of the driver is not the same as the version built into the MacOSX version off KStars.  They are different.  The INDI Web Manger version (which comes out as Sesto2) does not have as many controls, and no backlash compensation.  The Sesto2 and Esatto drivers in the built-in version of KStars OSX do have those features.
