Как изменить экран по умолчанию общий доступ по VNC порт на Mac ОС Х?

основываясь на информации, предоставленной Грегом в этом потоке, я написал сценарий bash, который автоматизирует процесс изменения порта прослушивания VNC вашей системы. Хорошо работает в моих тестах. Дайте мне знать, если у кого-то есть какие-либо проблемы с ним.
