I successfully installed v1.2.0 of obs-mac-virtualcam. Tools->Start Virtual Camera shows up in the OBS menu. When I launch the virtual camera I can't seem to find the virtual camera in any application I try from. Looking at the log file below there is obviously a problem, although I don't know how to quickly go about solving the problem. I am hoping someone on the forum will have a good suggestion.

The "Uninstalling" instructions at: https://github.com/johnboiles/obs-mac-virtualcam
talk about the following files.
/Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin
/Library/Application\ Support/obs-studio/plugins/obs-mac-virtualcam
I have confirmed both files exist. (I didn't want to uninstall them, just validate they were installed.)

The ons-mac-virtualcam package I used is:

I am having the exact same problem.

In summary: OBS and virtual cam installed. The installation is (at least partially) successful: The "Start Virtual Camera" option does show up in the Tools menu.

However: when selecting this option, nothing happens. (From brief guides, I expect it should open a dialogue? Nothing opens.) Trying various different video programs (Zoom, Teams, etc), no virtual camera seems to exist. The Tools menu entry in OBS, however, has changed to "Stop Virtual Camera".

The log file is similar to the one posted above. The only virtual cam-related error seems to be that the loading of the localised texts fails:

13:02:19.594: Failed to load 'en-US' text for module: 'obs-mac-virtualcam.so'

However, the rest seems to indicate that the module loads:

13:02:19.594: [obs-mac-virtualcam] version=1.2.0
13:02:19.594: ---------------------------------
13:02:19.594: Loaded Modules:
13:02:19.594: obs-mac-virtualcam.so

Does anyone have any ideas? Or at least: Can someone tell me what should happen then I select "Start Virtual Camera"? Should a dialogue open? Can I check somehow more reliably whether OBS thinks the virtual can is running?

Thanks,

M.
