Hello, I am not really a developer, but I seem to be running into a problem similar to this. I've been exporting Apple ProRes 4444 files + alpha perfectly for a long time, but on the Silicon M1 Max Macbooks it doesn't seem to work anymore. Mov-files exported with this codec appear black instead of transparant. How can I raise this issue/bug with Apple? It's a pretty important thing for editors / motion designers who are in need of exports + an alpha layer for their clients. Thanks!
