The note directive stating:
macOS Prevents mongod From Opening
macOS may prevent mongod from running after installation. If you receive a security error when starting mongod indicating that the developer could not be identified or verified, do the following to grant mongod access to run:
Open System Preferences
Select the Security and Privacy pane.
Under the General tab, click the button to the right of the message about mongod, labelled either Open Anyway or Allow Anyway depending on your version of macOS.
Should no longer apply due to the builds now being notarized.
Please test and remove this note.
