Ok, thanks for confirming - it must be something else then. I can see all the ResolveFX plugins, but cannot see any user installed ones.
I checked everything as you said and that’s what I had done. I put the OFX/Plugins folder in the root Library (not user Library), with the LMT.ofx.bundle inside that.
I was not aware about the hardware configuration but have switched that to CUDA and restarted.
I’ll keep looking for help on the Blackmagic forum, even though you are a key participant in most of the conversations I’ve found that seem related to this…
