Missing option to prefer external gpu
I am using a Sonnet EGPU with a Radeon RX570 (8GB), connected with Thunderbolt 3 on a 2018 Mac Mini, 32GB RAM 2667MHz, 3,2GHz processor. I do have "Prefer External GPU" menu in every app info box, except in iMovie. I've reset preferences, restarted Mac, tried to force using eGPU with set-egp.sh script with no luck... I'm exporting a 11GB movie with Intel UHD Graphics 630 with 1536MB... still waiting for Mac to finish. Very sad!
None gave a solution to the previous (and old) thread. Please help!!!
