ReiKey
ReiKey is a macOS security utility that scans for keyboard event taps and alerts you when new taps are installed.
What is ReiKey?
ReiKey is a macOS security utility for detecting keyboard event taps, a mechanism some software and malware can use to watch or filter keystrokes. It helps users monitor which processes have installed these taps and can alert them when a new keyboard event tap is added. The app is designed for Mac users who want more visibility into possible keylogging behavior or other software that intercepts keyboard input. ReiKey includes an on-demand scan window, menu bar access, configurable alerts, and preferences for how it runs. It also offers a command-line scan option for users who prefer terminal-based workflows. ReiKey is published by Objective-See, LLC as part of its macOS-focused security tools.

Safety overview
Status: Mostly safe
ReiKey is a legitimate security tool whose monitoring behavior matches its purpose. It may generate notifications about both suspicious software and normal macOS components, so alerts should be interpreted carefully rather than treated as proof of harm. The app can contact Objective-See to check for updates, and crash reporting may create limited network activity. Keep it only if you want keyboard-tap monitoring on your Mac.
Recommendation: Keep ReiKey if you want an extra layer of visibility into software that intercepts keyboard input. If you do not use its alerts or scans, you can remove it without affecting normal macOS operation.
