What is VNC Viewer?
VNC Viewer is a remote desktop application for macOS that helps you connect to and control another computer from your Mac. It is commonly used by IT staff, support teams, and individuals who need remote access to workstations, lab machines, or home computers. The app lets you open remote desktop sessions, interact with the keyboard and mouse as if you were sitting at the other machine, and save connection details for quicker access later. VNC Viewer can be used with RealVNC Server and also supports connections to compatible VNC servers, which makes it useful in mixed environments. On a Mac, users typically rely on it for remote administration, technical support, and accessing files or apps on another device without being physically present. RealVNC Limited publishes the software as part of its remote access product line.

Safety overview
Status: Mostly safe
VNC Viewer is legitimate remote access software, and its network access is normal for a remote desktop app. Because it can connect to other computers and may store connection details, you should use it only with systems you trust and protect your account and saved connections with strong credentials. If you no longer use remote access on this Mac, removing the app should only affect your ability to start remote sessions from VNC Viewer.
Recommendation: Keep VNC Viewer if you use your Mac to access other computers remotely. If you no longer need remote desktop access, you can remove it like any other app; doing so will stop you from opening saved VNC connections from this Mac.
