This is completely frustrating and looks like intrusion on my privately owned Mac. From a general point of view, this is not acceptable some actions are initiated on my Mac by someone else than myself. For development, i have installed Xcode. Every 3 or 6 months, all my environment stop working as Xcode disappear from my Mac without me being asked or informed and then checking on App store , it always correponds to a new version of Xcode being unavailable. This is an unbearable way of forcing user to update to a new version and quite bothering. How to stop such outside action to be initiated on my device?
