As a years-long subscriber to LMI, you don't get the sense they dedicate many resources to Mac support. One would have hoped this could have been resolved with Mojave in beta.
They still cash our checks though!
I'm looking forward to hearing from other about alternative products.
We are still on target to fully support Mojave in the coming days, and I definitely appreciate your patience while this gets finalized.
In the meantime, another user posted a possible workaround while connected to Mojave systems through LMI Pro: uncheck the "Grey Scale when inactive" box option in Options -> Color Quality -Advanced. (Thanks @tomiette for identifying this)
