You can use Remote Desktop to access a computer running Virtual Network Computing (VNC) software on macOS, Linux, or Windows, and view and interact with the computer's screen. VNC access is similar to the Control command in Remote Desktop.
Does VNC viewer work on Mac?
MacOS has a VNC Viewer already built into it. For the Server Address, type vnc://localhost:5944 where 5944 was the port we forwarded above. If you set up a password for your VNC session (and you should!) it will prompt you to enter it now.
Do I need VNC server on Mac?
A VNC server lets you control your Mac from another computer. The other computer does not need to be a Mac; it can be a Windows PC. There are a number of VNC servers available for the Mac. These are no longer needed with Mac OS X 10.4 and later.
