It's not free, so if you're looking for a free alternative, you could try Chrome Remote Desktop or DWService. The most popular Mac alternative is AnyDesk. There are many alternatives to TigerVNC for Mac if you are looking to replace it.I can say this after delivering VNC based solutions to customers for the last 7 seven years. For many (or even 'most' in my context) customers/cases, the VNC bandwidth requirement is no problem. TurboVNC/TigerVNC (or the Sun or ThinLinc versions of it) wins here.
