 - `prompt_user`: (default) show a user dialog for each blocking process found abort after three attempts to quit (only if user accepts to quit the apps, otherwise the update is cancelled).
 - `prompt_user_then_kill`: show a user dialog for each blocking process found, attempt to quit two times, kill the process finally.
 - `prompt_user_loop`: Like prompt-user, but clicking "Not Now", will just wait an hour, and then it will ask again.
+WARNING! It might block the MDM agent on the machine, as the scripts gets stuct in waiting until the hour has passed, possibly blocking for other management actions in this time.
 - `tell_user`: User will be showed a notification about the important update, but user is only allowed to quit and continue, and then we ask the app to quit.
 - `tell_user_then_kill`: Show dialog 2 times, and if the quitting fails, the blocking processes will be killed.
 - `kill`: kill process without prompting or giving the user a chance to save.
