Hyperkey
Hyperkey is a lightweight macOS utility that remaps a key into an extra modifier for custom keyboard shortcuts and faster workflows.
What is Hyperkey?
Hyperkey is a macOS utility for turning a chosen key into a Hyper key, a combined modifier that acts like Command, Control, Option, and Shift together. It helps people create additional keyboard shortcuts that are less likely to conflict with shortcuts already used by apps or macOS. The app is designed for users who want a simple way to expand their shortcut setup without using a larger remapping tool. Common uses include assigning Caps Lock or another key to trigger window management shortcuts, automation tools, and app-specific commands. Hyperkey focuses on a small, straightforward interface with minimal configuration, and it also supports a trackpad-based modifier gesture for users who prefer that workflow. It is published by Ryan Hanson for Mac users who want a focused keyboard productivity tool.

Safety overview
Status: Mostly safe
Hyperkey is a legitimate keyboard remapping utility for macOS. Its behavior is consistent with its purpose, but it may request Accessibility access or similar input-related permissions so it can modify key behavior and detect shortcut input. Those permissions are sensitive because they allow the app to observe and transform keyboard events, so only keep them enabled if you use the app and installed it from a trusted source.
Recommendation: Keep Hyperkey if you actively use custom keyboard shortcuts or a Hyper key workflow on your Mac. If you no longer use it, you can remove it and revoke any Accessibility permission it was granted; your remapped-key shortcuts and related workflows will stop working until you reinstall or replace it.
