MacOS Setup
Bypass Apple's Gatekeeper warning.
macOS 15 (Sequoia) and later
- Double-click CheckMate. When the warning appears, click Done— don’t move it to the Trash.
- Open System Settings → Privacy & Security.
- Scroll to the Security section, where you’ll see a note that CheckMate was blocked.
- Click Open Anyway and confirm with Touch ID or your password.
macOS 14 (Sonoma) and earlier
- Right-click (or Control-click) CheckMate in Finder.
- Choose Open, then Open again in the dialog that follows.
Prefer the Terminal?
Clear the quarantine flag directly, adjusting the path if you moved the app elsewhere:
xattr -cr /Applications/CheckMate.app
