I have installed tigervnc in Mac but when I ran python3 -m pyvirtualdisplay.examples.vncserver I am getting

I understand this is a Xvnc wrapper, but somehow brew install tiger-vnc didn't install Xvnc?

which Xvnc in the terminal returns Xvnc not found

Can someone point me to a right direction?

On Ubuntu Linux symlinks are created for Xvnc:

/usr/bin/Xvnc -> /etc/alternatives/Xvnc*
/etc/alternatives/Xvnc -> /usr/bin/Xtigervnc*

You can do the same.
Can you start Xtigervnc in console?
I can rename Xvnc to Xtigervnc in the next version.

Thanks for the reply, I used brew install tiger-vnc to install TigerVnc for Mac but I don't see Xvnc or Xtigervnc in /usr/bin/ or /opt/homebrew/bin. Trying to run Xvnc or Xtigervnc as you suggested returns command not found. However I am able to run TigerVNC by running vncviewer command. I guess I can try to symlink vncviewer to Xvnc and see

A VNC viewer and a VNC server are two different pieces of software.

Please check if Xvnc is installed on Mac.

Xvnc is Linux specific according to the README:
https://github.com/TigerVNC/tigervnc

Unix/Linux-Specific (not Mac)

The Unix/Linux version of TigerVNC contains the following programs:

    Xvnc - the TigerVNC Server for Unix. Xvnc is both a VNC server and an X
        server with a "virtual" framebuffer. You should normally use the vncserver service to start Xvnc.
