I'm a little confused. FCUSB is in your supported devices section with the indi drivers with support for 32 and 64-bit OSX. But in the page to which they refer (cloudmakers) I can see only for linux and raspbian. In EKOS 2.8.4 I can't see the option to choose FCUSB in the focuser section. What do I have to do to select this focuser? Thank you and regards from Spain.

I also asked about this problem before.
A solution is posted on this page.
www.indilib.org/forum/ekos/525-ekos-on-mac-os-x.html?start=1332

I did it, but now I have an error message...
"Driver indi_fcusb_focuser was not found on the system. Please make sure the package that provides the 'indi_fcusb_focuser' binary is installed."
Please, see attached image. Thank you for your attention.

Ok, I've found the solution. Profile editor-> uncheck mode-local an check mode-remote...
I'm leaving the post in case anyone's been through the same thing.
Regards...

Are you using only OSX?
In this case, the INST server is handled separately from the server built into Kstars and the server distributed by the cloud maker.
To use the server driver provided by the cloud maker, start up the server application and select the driver to use.
Then change the local checkbox to the remote host of Ekos setting.
At that point you can leave that address as a local host.

You can now use the server of the cloud maker.
