First of all, thank you for creating a really helpful NDI plugin for my production workflow.
Unfortunately, I have been unable to get it to work with any version of FCP past 11.0.1 which came out in March of 2025. Your plugin still works great with that version. I can even run both that version and the current release of FCP side by side on my machine. In 11.0.1 NDI appears as an option in A/V Output in FCP's playback settings. In every version after that, it does not. With every new release of FCP or NDI tools since then, I have downloaded the latest version hoping for a fix, but that hasn't happened.
I am finally finished with my previous projects that relied on the plugin, and would like to update my FCP. I found a workaround using an NDI plugin for OBS Studio that allows me to send NDI out from FCP via a screen capture of my output display. This is laggy with more overhead, and relies on having another external display to output to.
This problem is addressed in this bug report:
https://docs.ndi.video/all/faq/common-issues/im-having-issues-with-final-cut-proAlthough current problem appears to be tied to the Final Cut version and not the Mac OS version.
There was a previous Mac OS issue that was fixed by following these instructions:

I'd love to help get your plugin working again. Please let me know if there is anything I can do or test to help.
Thank you.
