Recovery mac os from usb

Создание загружаемого установщика для macOS

В качестве загрузочного диска для установки операционной системы на компьютер Mac можно использовать внешний диск или дополнительный том.

Эти расширенные инструкции предназначены в первую очередь для системных администраторов и других пользователей, имеющих опыт работы с командной строкой. Загружаемый установщик не требуется для обновления macOS или переустановки macOS, но он может оказаться удобен, если требуется выполнить установку на несколько компьютеров, не загружая установщик заново каждый раз.

Что нужно для создания загружаемого установщика:

• USB-накопитель или другой дополнительный том, отформатированный в Mac OS Extended, на котором есть не менее 14 ГБ свободного пространства;
• загруженный установщик для macOS Big Sur, Catalina, Mojave, High Sierra или El Capitan.

Загрузка macOS

• Загрузка macOS Big Sur, macOS Catalina, macOS Mojave или macOS High Sierra
  Эти элементы загружаются в папку «Программы» в виде приложения с именем «Установка macOS [ название версии ]». Если после загрузки запустится установщик, завершите его работу без продолжения установки. Чтобы получить подходящий установщик, выполняйте загрузку с компьютера Mac, на котором используется macOS Sierra 10.12.5 или более поздней версии либо El Capitan 10.11.6. Корпоративным администраторам следует производить загрузку с сайта Apple, а не с сервера обновления ПО, размещенного в локальной сети.
• Загрузка OS X El Capitan
  В результате этого действия загрузится образ диска с именем InstallMacOSX.dmg. На компьютере Mac, совместимом с El Capitan, откройте образ диска и запустите с него установщик с именем InstallMacOSX.pkg. Приложение с именем «Установка OS X El Capitan» будет установлено в папку «Программы». Загружаемый установщик создается именно из этого приложения, а не из образа диска или установщика .pkg.

Использование команды createinstallmedia в приложении «Терминал»

1. Подключите USB-накопитель или другой том, используемый для загружаемого установщика.
2. Откройте приложение «Терминал» в подпапке «Утилиты» папки «Программы».
3. Введите или вставьте в приложение «Терминал» одну из следующих команд. Предполагается, что установщик находится в папке «Программы», а имя MyVolume обозначает USB-накопитель или другой используемый вами том. Укажите вместо MyVolume имя своего тома в следующих командах.

Big Sur*:

Catalina*:

Mojave*:

High Sierra*:

El Capitan:

* Если на компьютере Mac установлена операционная система macOS Sierra или более ранней версии, включите аргумент —applicationpath и путь установки аналогично тому, как это делается в случае команды для El Capitan.

После набора команды

1. Нажмите «Ввод», чтобы ввести команду.
2. При появлении запроса введите пароль администратора и нажмите клавишу «Ввод» еще раз. При вводе пароля приложение «Терминал» не отображает вводимые символы.
3. При появлении запроса нажмите клавишу Y , чтобы подтвердить удаление всех данных на томе, затем клавишу «Ввод». Приложение «Терминал» показывает прогресс по мере стирания тома.
4. После стирания тома может быть отображено предупреждение о том, что приложению «Терминал» требуется доступ к файлам на съемном томе. Нажмите «OK», чтобы продолжить копирование.
5. Когда приложение «Терминал» сообщит о завершении процесса, имя тома будет совпадать с именем загруженного установщика, например «Установка macOS Big Sur». После этого можно закрыть приложение «Терминал» и извлечь том.
