Is there no way to force this? I can't get some RED footage to play on my Mac Pro trash can but on my laptop with 12.5 it plays only when I uncheck that box. It seems 14 is trying to use the GPU and not realizing it's not working so it's not switching to CPU.
EDIT: Nevermind. More searching through the forum and this issue and I changed GPU mode to Metal and it plays back now. Thanks anyway.
