[C++] Neither dylib plugin nor bundle loads on macOS

[Samuel5E6F]

(this can be replicated with the ExportController sample project)

Works fine on Windows, but on macOS nothing [relevant] appears in my Export menu. I copy the file to:

/Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore

I have tried generating a dylib for my project, and I've tried with a bundle. In both cases nothing appears, though when I open Premiere Pro it does say its loading it on the screen (along with the Adobe logo).

I've also tried holding down `shift` to get rid of the plugin cache, and looking in `~/Library/Logs/Adobe/Adobe Premiere Pro 2021/*.log` but there are no error, warning, or info messages. Maybe I've got a permissions issue, am building for the wrong architecture, need to bind a certain additional library, need to do some code-signing, or something similar?

How do I figure out what's going wrong?

Based on our direct conversation, waiting a few moments fixed the issue; let me know if that wasn't the case.

@Bruce BullisSorry no the "waiting a few moments" solution was for a different problem.

This plugin works on Windows but not macOS, and I'm getting no log message telling me why it's failing. Am I looking in the wrong places for the logfile? - What linker and other build flags do I need? - Does the output need to be bundled? - Does the bundle need to be code signed? - Am I putting the file in the right place? - Does it need certain filesystem permissions and file attributes?

(I've got no idea why it's not appearing in the "Export" menu so I'm guessing here)

If I download the PPro C++ SDK and (without modification) build the ExportController project on my Intel Mac, the resulting bundle is created:

/Library/Application Support/Adobe/Common/Plug-Ins/7.0/MediaCore/Debug/ExportController.bundle

If I then launch PPro, and make a sequence active, I can trigger the ExportController from PPro's File --> Export menu. 

Where does your experience, depart from [above]?
