One of the more popular free VNC tools used by our clients, RealVNC, now offers their server product under the name VNC Connect. Customers often ask us whether they need VNC Connect on their Mac running macOS1.
Apple's macOS includes a built-in VNC server, by default. We enable this for every hosted Mac running any version of macOS before releasing the server to a customer.
To connect to one of our Mac servers running macOS, you need a VNC client like the one RealVNC offers, VNC Viewer. VNC Connect is not required.
1. macOS may be interchangeable with OS X, the name used for previous versions of Apple's Mac operating system. ↩
