I downloaded the TP-PLC App from the TP-Link Website and moved the Install folder to the Applications folder as prompted. I then opened my launch pad and observed the TP-PLC app. I double clicked the icon to open the app and got a message from apple saying the app needs to be updated by the developer becasue apple was unable to check it for malecious software. I uninstalled and attempted a second time and got the same resonse. It appears, by the date listed in the download website, that the app was last updated in Nov. of 2020. Any insights?
