I confirm the problem with virtual camera
The Virtual Camera seems to work fine on a fresh install of OBS Studio. Did you both update from an older version?
@dx8ug Please provide a log file.

I updated from a previous version using the built-in updater.
I don't know what a "fresh install" means.
I also downloaded the DMG from the website and replaced the app, and that didn't help.
yes, I updated from the previous version using the built-in updater.

A "fresh install" is installing OBS when no version of OBS is currently installed. Basically:
I just tried updating from OBS Studio 30.0.2 to 30.1.0 and had no issues with the virtual camera at any point. What version did you both update from?
I can assume that version 30.0.2 was previously used, since I always update when possible
trying to do a fresh install
I updated from 30.0.2.
Moving 30.0.2 to the trash, emptying it, and then installing 3.1.0 from the DMG did bring up the dialog that then prompted me to approve the app in System Preferences (Security / Privacy settings). Clicking "Allow" and then running OBS again did fix the issue. Thank you for your help @RytoEX.
It seems like there's some issue with upgrading the app via the updater that causes it to break / skip this important part.
after a fresh installation with a reboot, the issue was fix (there was no notification about permissions) without a reboot, even with a reinstallation the issue remained Thank you
Usually this "not found" error is caused by the extension updating successfully, but macOS failing to start the updated version after the update.
If that's the case, logging out and back in should solve it, a full reboot shouldn't even be required.
If someone has this issue and logging out and in doesn't solve it, could they post the output of the systemextensionsctl list
command in Terminal?
I can confirm this issue. Was fixed by rolling back to 30.0.2

The macOS Virtual Camera in OBS Studio 30.1.0 works fine on macOS 13 and 14, and should work fine on macOS 12.3 or later (and even on macOS 11, but using the old implementation, which the user should not be able to tell). This issue is not that it is actually not working at all, but that it apparently does not work after updating OBS for some reason, probably the macOS CMIO System Extension update mechanism not working correctly.
As mentioned above, please do not roll back when you encounter this issue. Please provide the output of systemextensionsctl list
from Terminal. The virtual camera itself is not broken in 30.1.0, as multiple people have confirmed.
I've also had this issue. After upgrading to 30.1.0, (on MacOS 12.7.4 Intel Mac) the virtual camera stopped working. I absolutely flailed around, reinstalling, etc. trying many things until it started working again. One of the last things that I tried was running this command on a fresh install of 30.1.1: sudo find /Applications/OBS.app/ -type f -exec xattr -d 'com.apple.quarantine' '{}' ';'
which strips the 'quarantine' attribute from all files in the OBS application. I'm not sure that's what fixed it, but it did work shortly thereafter. HTH someone

What we really need is the output of systemextensionsctl list
from Terminal when someone is in a broken state.
@risacher Actually, on macOS 12, you still get the old DAL extension, not the new CMIO extension, so your problem is probably not the same as this.
I currently find myself in a broken state.

Can you screenshot the error that you receive when you try to start Virtual Camera output in OBS 30.1?
With pleasure. Note, I've already attempted the privacy change that others had previously described.
That error indicates that your device is a managed or provisioned system, and the provisioner did not grant you permission to install system extensions. This is unrelated to the errors upthread.
Thanks @jcm93. Apologies for the noise. Do you know what the system extension required is?
There is not a name for it, it's authored by OBS and is just a small CMIO extension that accepts frames received from OBS and presents them as a camera device. This is the only supported way to achieve 'virtual camera' functionality in macOS 14+. More details can be found in Apple's documentation or the plugin code.
Currently, what we need to debug this are these things:
systemextensionsctl list
when you get the "Could not find virtual camera" error message.systemextensionsctl list
after rebooting macOS.I again encountered the same problem after auto-updating on 30.1.2
here is the output of the command systemextensionsctl list
when the error appears

If anyone runs into this again, please file an Apple Feedback when OBS is open and you get the "Could not find virtual camera" error message. Post the Feedback ID here.
That error indicates that your device is a managed or provisioned system, and the provisioner did not grant you permission to install system extensions. This is unrelated to the errors upthread.
@jcm93 dufferenterprise's issue (while not the one addressed in this thread) is popping up on my system, but my user is in sudo group so in theory I should be able overridable--do you happen to know of a cli command or way to re-build/re-register the plug-in?
Just to add back, for my use case the MDM admin added the following system extension:
com.obsproject.obs-studio.mac-camera-extension team identifier 2MMRE5MTB8

It appears that, in rare instances, users can hit the "Could not find virtual camera" error despite the extension being installed AND running. This appears to be due to some sort of bundle lookup failure in systemextensionsctl
, and persists through logout/in as well as reboot, though the one user that's run into it resolved it by reinstalling OBS.
This is the output of systemextensionsctl list
when that error is encountered (via a user in support on macOS 14.4.1):

Posting for the sake of public tracking in case this is of interest to any Apple people reading. No users in this thread or #9912 appear to have hit this specific failure mode and posted documentation.
