How can I remove an unwanted Just Join app from Mac.? Trying to remove Just.join app. without success message states &quot;can't be removed because it's open&quot; when I tried to open it states&quot;can't open because it may be damaged&quot;.
can anybody tell me how to proceed please.
System High Sierra (10.13.6
Open Activity Monitor and force the app to quit. If you still can’t remove it you might need to use a safe boot or safe log in holding shift when you boot or shift when you enter your password to log in again to prevent the app from starting.
