## What it is
Sentinel is a native macOS SwiftUI application providing a GUI for managing Gatekeeper settings. It lets users unquarantine apps by drag-and-drop or Finder right-click, ad-hoc self-sign apps, and configure Gatekeeper behavior.

## Use cases
- remove quarantine attribute from downloaded mac apps
- disable gatekeeper warnings on macos
- self-sign an unsigned app with ad-hoc certificate
- unquarantine apps from finder context menu
- open apps blocked by 'cannot be opened because developer cannot be verified'

## When to choose
- you frequently install unsigned or unnotarized apps on macOS
- you want a GUI instead of xattr/codesign terminal commands
- you need a Finder extension for quick unquarantining

## When to avoid
- you need active support or new features - development is on hold
- you are on macOS earlier than Ventura (13.0)
- you need enterprise-wide MDM gatekeeper policy management
