Are there other VNC servers for macOS other than the built in one? The built in VNC server is not sufficient for my needs as I cannot change settings of the VNC server.

I tried to run Vine Server (OSXvnc) but the application crashes on launch.

Are there any other VNC servers that run on macOS?



Edit-

When I connect to the built-in VNC server, I observe that it is slow. I tried to make the VNC connection faster by reducing the color level of the VNC connection so that less bandwidth is used. However, the built-in VNC server refuses to connect.

I am looking for VNC server which supports connections with reduced color level so that the VNC connection is faster.
As far as I know there are no other freely available, generic VNC servers for macOS besides the built-in one and the OSXvnc program. 

There exist a commercial VNC server from TightVNC, but it is not generic in the sense that it allows VNC access to your macOS desktop - rather it is to be built in to a specific application to allow remote access to that only.

One thing you could try is a newer "fork" of OSXvnc (or rather just seem to be some guys providing updates on the seemingly otherwise abandoned OSXvnc project) here:

There are even some pull-requests with bugfixes for a few bugs, so you might be lucky that one of those fixes your crash.
