MacOS Setup

Bypass Apple's Gatekeeper warning.


macOS 15 (Sequoia) and later

  1. Double-click CheckMate. When the warning appears, click Done— don’t move it to the Trash.
  2. Open System Settings → Privacy & Security.
  3. Scroll to the Security section, where you’ll see a note that CheckMate was blocked.
  4. Click Open Anyway and confirm with Touch ID or your password.

macOS 14 (Sonoma) and earlier

  1. Right-click (or Control-click) CheckMate in Finder.
  2. 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
