A few machines running Ubuntu 18.04 have to be accessed remotely through VNC.

On Ubuntu, I can use Remmina Remote Desktop Client to connect to the VNC server. The VNC server on Ubuntu is setup via the default Desktop Sharing:

Desktop Sharing in Ubuntu

I want to connect to that Ubuntu session via VNC from a macOS client.

I tried using the "hidden" default VNC client by going through Finder and using +k, and:






yet it states that version of the server cannot be identified. I am assuming the the default client works only for macOS servers.

Is there, and if so which, a VNC server can connect to an Linux server? I prefer the solution to be open source or freeware. A paid solution is not an option for me, yet feel free to name it to give a working solution.


There exist many modern VNC clients for macOS that supports connecting to Linux servers. Free ones include TigerVNC and RealVNC Viewer.

  • Both clients do not reckognize the security setting: Unable to connect to VNC Server using your chosen security setting or in case of tigerVnc: No matching security types. – k0pernikus Apr 2 at 11:58
  • You can solve this by running the following on the server: “gsettings set org.gnome.Vino require-encryption false”. If you prefer not doing that, post your VNC server configuration details so that we can see how you have it configured. – jksoegaard Apr 2 at 16:32
  • I confirm that after setting this variable to false I was able to connect to the Ubuntu 18 server with both RealVNC Viewer and the integrated macOS Screen Sharing application. – Liviu Ionescu Jun 14 at 16:49
