It would be a dream to use Airplay for  sharing the OBS output using  the window modus. However, whenever switching the window to full screen, I can’t control OBS anymore as the main screen goes black, even when using different spaces. Also sync screens is not an option here as I only get the Airplay output.

So Airplay isn’t a good choice here, the reason why I have been falling back now to NDI to transmit my output to another machine.

It turned out, however, that the NDI plugin is not working anymore with the revamped OBS version 28 because the QT5 sources are not correctly referenced in the plugin according to the log file.

So the only choice is now to go back to version 27 until this error has been corrected.
