ManyCam no longer working

If you had a slight idea about virtual cameras on PCs, you would have certainly heard about ManyCam. Regarded as one of the best webcam software available for free. ManyCam allows you to create video effects from your webcam with several features like the ability to change backgrounds, add face masks. And enable picture-in-picture mode while you are sharing your screen or live-streaming. In this article, we are going to talk about What to do if ManyCam no longer working. Let’s begin!

As useful as it may be, you can be prone to some issues on ManyCam like you would with any piece of software. But rest assured we might have some solutions for the problems you are facing with ManyCam. The following post will help you fix issues with ManyCam now working on your system. And what you can do to avoid such problems in the first place.

Remove official signature from your video calling software on Mac

Several users are complaining that the latest version of Zoom, Skype, and GoToMeeting are not working with ManyCam on macOS. While for many the ManyCam does not show up as an option for setting the virtual camera. Other users are experiencing problems in the video feed with ManyCam enabled.

The problem seems to be happening because of a feature called ‘Library validation’ that has been enabled across various video calling software, which restricts plugins that aren’t signed by Apple or the video software (in this case, Zoom). The only way to solve this is by unsigning the latest version of Zoom or the video calling app that you use and then enable ManyCam on it. You can do so by following the steps below:

  • Update your Zoom app or the video calling app that you use to the latest version on Mac by opening the app, heading over to the Menu bar > App name > Check for updates, and then updating the app the latest version. After installing the update, force-close the zoom app.
  • Install the Xcode tool on your Mac by opening Terminal and entering the following command and hitting the Enter key:
Xcode-select --install

Wait for Xcode to install on your system and then move on to the next step.

  • You can now proceed to unsign the video calling software by typing the following command and then hitting the Enter key:
sudo codesign --remove-signature /Applications/<app name>

For example, 
If you're using Zoom, then you should use the command - sudo codesign --remove-signature /Applications/


Enter the command "sudo codesign --remove-signature"
Then drag the video calling app from the Applications folder to the Terminal window
  • You can now open the video calling app and enable ManyCam as your default camera option.

That’s it! ManyCam should now start working on your video calling app.

Install an earlier version of the video conference software

Most of the time, the reason for a feature or an app to not work any longer on your computer will be a recent update. You can uninstall the current version of the video calling app on a Mac by opening Finder > Applications, locating the video calling app, and also dragging it to the Trash icon. After that, you can head over the official website of the app and search for older versions of the app to download. Once the download completes, install it and open it to enable ManyCam inside the video conference software.

Disable Hardware Acceleration

In some systems, ManyCam could use better hardware components to render details better, switch presets, or load higher quality videos. But for systems with basic configuration, disabling hardware acceleration on ManyCam can make it work better. You can disable hardware acceleration by opening the ManyCam app, heading over to ManyCam Settings > General, and toggling OFF the ‘Hardware Acceleration’ option.

Change integrated webcam settings

This option can only be tweaked when using ManyCam on a Windows PC. That’s because, for Windows, ManyCam offers a way to adjust settings of the integrated webcam. You can change the integrated webcam settings on your Windows PC from right within ManyCam by right-clicking on the Main Live Window, selecting Properties, and disabling AutoFocus, Face Tracking, and RightLight.

Disable Asynchronous frame transmission

Another Windows-only option ManyCam offers is Asynchronous frame transmission that can be enabled for PC’s with at least a quad-core CPU to improve the frame rate. However, enabling it on your PC does not mean ManyCam will work for you. If you are facing issues, then you can disable Asynchronous frame transmission by heading over to ManyCam > Settings > General.
