QGIS 3.10 plugin provider activate issue

Hi QGIS noob here. So I’m trying to access the OTB in QGIS 3.10. It’s visible in, Processing Toolbox > Options > Providers, however, when I attempt to activate it I get the following:

Wrong value for parameter “OTB folder”:

‘’ does not exist. OTB provider will be disabled"

I have no idea what this means. I’ve added the OTB plugin repo, which I assume is the provider.

One thing I’m aiming to do is set up a bootable Linux partition on my Mac as there’s a whole plethora of scientific analysis programs that are Linux based that I’d rather run fully installed, rather than on a restricted virtual set up. I’m not sure if this would be a better option for running QGIS and the OTB?

Any input would be gratefully received.

FYI, my system is an old Mac Pro 5,1 running OSX 10.14.6

FACEPALM!

Sussed it out. The option to add application folder path was hidden. All sorted.
