ChronyControl
ChronyControl is a Mac utility for installing, configuring, and monitoring the chronyd time synchronization daemon.
What is ChronyControl?
ChronyControl is a native Mac utility for working with chronyd, the Chrony network time synchronization daemon. It helps users install Chrony components, manage configuration, and monitor timekeeping behavior from a graphical interface instead of relying entirely on Terminal commands. The app is aimed at Mac users who want more control over clock synchronization than the built-in ntpd workflow typically provides, especially on systems that are not continuously online. ChronyControl also serves as a front end to the chronyc tool and includes tools for editing configuration settings and checking daemon status. This makes it useful for advanced home users, labs, and technical environments where accurate timekeeping matters. The software is published by Bryan Christianson for macOS.

Safety overview
Status: Mostly safe
ChronyControl is legitimate utility software for managing time synchronization on macOS, but its purpose involves installing and controlling chronyd, which can affect system timekeeping behavior. That is consistent with the app's function, yet users should only use it if they understand why they want an alternative to the default macOS time sync setup. If you installed it intentionally for Chrony or NTP-related tasks, its behavior is proportionate to that purpose.
Recommendation: Keep ChronyControl if you actively use Chrony on your Mac or need hands-on control of time synchronization settings. If you do not use chronyd or no longer need advanced clock-sync management, you can remove the app to simplify your system without affecting normal Mac use of unrelated apps.
