Google Chrome behaves badly, registering itself in Login Items on every startup and trying to stay resident on the system. macOS Ventura and later systems have a system that notifies you when something is registered in Login Items, and when the condition is met, a notification banner appears. These appears every time we start up Google Chrome. This is the nightmare.
Login Items in macOS are based on a mechanism called LaunchAgents or LaunchDaemons. By registering information on programs to be launched at system startup in a plist file, background processes can be driven.
