+
+##### Run influx CLI on macOS Catalina
+
+macOS Catalina requires downloaded binaries to be signed by registered Apple developers.
+Currently, when you first attempt to run `influx`, macOS prevents it from running.
+To manually authorize the binary:
+
+1. Attempt to run the `influx`.
+2. Open **System Preferences** and click **Security & Privacy**.
+3. Under the **General** tab, there is a message about `influx` being blocked.
+   Click **Open Anyway**.
+
+We are in the process of updating our build process to ensure released binaries are signed by InfluxData.
