I have the latest QGis installed version 3.20 and the Orfeo toolbox should have come with it. I am working on iMac 2020 Big Sur version 11.4, there is no destination folder for the OTB:

When I activate by pressing on the button I get the following warning:

> 
> Wrong value for parameter "OTB folder":
> '' does not exist. OTB provider will be disabled
> 
>

Any ideas on how to progress?
