UVC camera not available in Lightburn on MacOS

Hi. I’m trying to get my 16MP USB camera to be recognised by Lightburn, but without success. The camera menu remains empty. I’ve tried all of the suggestions (everything up to date, different USB socket tried, starting in safe mode etc etc). The camera works with Facetime BTW.

The system info for the camera is:

      UVC Camera VendorID_13028 ProductID_664

Has anyone any suggestion for what I can do to get this working?

First, make sure, no other application is accessing the camera.

Did you allow LightBurn to access the camera in the Privacy Settings of MacOS?

Check out this page for instructions:

Thanks Aaron. I’ve tried with nothing else running, plus in safe mode. The odd thing is that Lightburn isn’t asking for access to my camera at all. I’ve reset privacy settings for lightburn, and when I next launch it I am asked for file access permission only, never camera access.

I don’t think, you need to run in Safe Mode. In fact, this might even cause issues. Please do a clean reboot before trying again.

Which version of MacOS are you running and which camera are you using exactly?

I just tried safe mode to see if that made any difference. I just boot normally at the moment and have rebooted multiple times.

Using Sequoia 15.3.2

I’ve just launched Lightburn from the command line, and this is what’s reported…

Using the core prefs dir
QMetaObject::connectSlotsByName: No matching signal for on_actionSettings_triggered()
QMetaObject::connectSlotsByName: No matching signal for on_actionEdit_GameControllers_triggered()

I see that the camera is found, but nothing appears in the UI. Do you think the libpng warning might be relevant?

I believe the camera is a neje camera that they sell for use with Lightburn.

Thanks for this test. This report should provide enough information to identify the problem.
@JediJeremy , could you take a look at this?
