TeamViewer
TeamViewer is a remote access and screen sharing app for macOS that lets you connect to and support other devices over the internet.
What is TeamViewer?
TeamViewer is a remote access, remote support, and screen sharing application published by TeamViewer Germany GmbH. On macOS, it is commonly used to connect to another computer for troubleshooting, unattended access, file transfer, or collaborative support sessions. The app can work across platforms, so Mac users may encounter it in home support setups, IT help desks, and business remote administration workflows. To function fully on macOS, it typically needs system permissions such as Screen Recording, Accessibility, and sometimes Full Disk Access, because those permissions allow remote viewing and control features to work correctly. TeamViewer may also install supporting background components so connections and device management features are available when needed. Most users install it intentionally, but it can remain present after temporary support sessions if it was not fully removed.

Safety overview
Status: Mostly safe
TeamViewer is a legitimate commercial remote access tool, but it can grant broad visibility and control over a Mac when configured for remote control. That makes it safe when you installed and use it intentionally, but sensitive if it appears unexpectedly or still has background access and macOS permissions you no longer want active.
Recommendation: Keep it if you actively use remote support or unattended access. If you only used it for a one-time support session or no longer recognize it, review its login items, background components, and macOS privacy permissions, then remove it if unused.
