What are you referring to as “Live Preview boxes”?

Could you share a screen cap of what you’re seeing?

Is the RX580 officially supported by MacOS (I assume you’re using an x86 Mac Pro)?

I did a google search and the only references to it are hackintoshes running opencore.

I’d recommend also posting your Mac model as well as the OS version you are using.



Are you able to upload a sample file you are seeing this with?

Have you tested these same files on another platform, such as iPhone, iPad, or Apple TV?

iPhone supports the same files
