Problem: Clickshare has no sound when sharing

Solution: To resolve this issue, you will need to install Soundflower

Challenge: When prompted during installation, a security alert might appear. Read the explanation below carefully and then restart the process.

ERROR: Signed Version for macOS Catalina (10.15) and earlier. This issue is not seen on Sonoma (15) and other later versions.

The Soundflower extension is signed, but the installer is not! You will have to hold the control key down to open the Soundflower.pkg installer for the first time.

Info! To find instructions for installing Soundflower on macOS version 10.15 or newer, see KB4666.  
PLEASE READ! NEW SECURITY STEPS REQUIRED BY APPLE
The first time you run the installer Soundflower.pkg, it will ask for your admin password and will FAIL! A security alert will appear, with a button to take you to System Preferences Security & Privacy - General pane. Once there, there should be an Allow button (**) that you will need to click on to give permission to use Soundflower (developer: MATT INGALLS). Then, RUN THE INSTALLER AGAIN. It should inform your installation was successful.
Allow Button (**)
If you see an Open Anyway Button in the Security Preferences, this is something different!!! Most likely because you tried (and failed) opening the installer by double-clicking without holding down the control key. If so, click the Open Anyway button which will display another window. Then click the Open button in that window to launch the installer. Now you can follow the instructions above to get the "Allow" button to appear in the Security Preferences.
Info! This is only the Soundflower kernel extension. The SoundflowerBed app is retired. This has been replaced by automatic detection and installation during the installation of the clickshare app.

Detailed instructions:

  1. Start the installation of the Soundflower plugin and wait until the error message is displayed, do not close the window with the error message at this time.


  2. In the upper left corner of the screen click the Apple logo.
     

  3. Select System Preferences... from the context menu.


  4. In the System Preferences window, click the Security & Privacy icon.


  5. In the Security & Privacy window select the General tab at the top if it is not already selected.
    Click the Allow button in the lower right corner of the screen, if the Allow button is greyed out please click the lock icon in the lower-left corner of the window and enter your administrative username and password to unlock.


  6. Once the Soundflower installer has been allowed you can close the original Soundflower installer window and then start the installer again, the software should now successfully install.
