Use virtual camera devices with Discord, Zoom and Microsoft Teams on macOS devices (Intel 80386-style and Apple Silicon).
This guide is designed to be a basic quick start guide with CoreMediaIO DAL Virtual Camera Guides for those who are proficient with computing systems. It's not comprehensive and support is not guaranteed. Really, it's just to help my friend get VTuber running on his Microsoft Teams classes.

So you're trying to get Vtuber running on your Microsoft Teams classes, huh? alright then...
Firstly, download the latest version of either program for your respective platforms:
OBS offers more option and granularity while Webcamoid is convenient for those who only need a basic virtual camera setup. The Virtual Camera feature is only available in newer versions of OBS, so if you're running an older version of OBS you should update.
Note: You may need to Right Click > Open for Webcamoid in order to bypass the security warning, as it is not code-signed.
Create a scene with OBS, add a source input (e.g to record osu!, use Window Capture and select the osu! window - which must be on your current desktop) and then click the Start Virtual Camera option on the right-hand control pane.
Configure a source in the Sources area, then in Settings enable the Virtual Camera. Add a virtual camera in Settings > Output by enabling the checkbox, then in the Devices box click Add. You can name your new virtual camera before enabling it in the dropdown menu.
WARNING: There are security implications to removing code-signed signatures. Furthermore, stuffing something up may cause something to go very, very wrong (although this is quite unlikely) and I'm not responsible if that happens. Make a backup of any program you code-sign and don't type any command you don't understand or fully trust.
With your virtual camera device enabled, they can now be used with applications like Discord, Google Meet, Microsoft Teams, Skype, Cisco Webex, Zoom, and more!
However, due to increased security limitations of DAL plugins on macOS, some applications may need additional steps to work. You could sign the with an Apple Developer ID plugin, but that costs money and I'm saving up for a truck-kun.
On Microsoft Teams, virtual cameras work out of the box. Head to Microsoft Teams > Settings > Devices and under video options, select the OBS Virtual Camera or your named Webcamoid virtual camera device in the dropdown.
On other applications like Zoom and Discord, you need to run the following command:
sudo codesign --remove-signature "/Applications/Your Application.app"
where /Applications/Your Application.app is the path to your application. If the command fails, install Xcode Developer Command Line tools with this command:
sudo xcode-select --install
sudo is a command that is placed before any command you run to run as root. With macOS sudo prompts, you'll be asked with a
Password:
input, and you'll be able to enter your password there before hitting Return. You won't be able to see any of the characters you typed, however.
You might also need to run this command for helper programs and dependencies. For example in Discord:
sudo codesign --remove-signature "/Applications/Discord.app/Contents/Frameworks/Discord Helper (Renderer).app"
Verify your drivers are correctly enabled by running the system_profiler SPCameraDataType command in Terminal.
You may receive output such as the one below:

On Apple Silicon systems, you may receive an incompatible architecture or bad arch error - this is safe to ignore.
Often times, this will be the best way to troubleshoot whether your virtual camera is working or not - however sometimes the error messages can be deceptive. If you're still experiencing issues with it, ask a question or check for threads with similar errenous behaviour on the OBS forums.
