What's inside gibMacOS

  1. Overview of gibMacOS

    master
    gibMacOS is a Python 2/3 script designed to download macOS components directly from Apple's servers. It can also be used on Windows to build Internet Recovery USB installers for macOS versions up to Catalina, provided you have dd and 7zip installed.

  2. Install macOS 11 (Big Sur) or newer on macOS

    master

    For macOS 11 (Big Sur) and later, Apple distributes the OS via an InstallAssistant.pkg file.

    When running on macOS, you do not need to use BuildmacOSInstallApp.command to create the install application. Instead, simply run the InstallAssistant.pkg file, which will automatically place the macOS install application into your /Applications folder.

  3. Build Internet Recovery USB installers on Windows

    master

    To build Internet Recovery USB installers from Windows, you must use the MakeInstall functionality. This requires the following third-party tools installed on your Windows system:

    Important Compatibility Note: Due to changes in Apple's distribution methods starting with macOS 11 (Big Sur), MakeInstall on Windows only works for macOS versions up to Catalina. It cannot be used to build Internet Recovery USBs for macOS 11 or newer.
