What is Blank hard drive disk images (100MB HFS up to 30GB HFS+)?

All these download files consist of extremely compressed empty disk images for emulators (such as SheepShaver or Basilisk II) that are to be used as hard drive to store files and/or the operating system. Once inflated, they will instantly take the whole space they are marked at. These empty disk images range from 3GB HFS formated (appropriate for Mac OS 6, 7 or 8.0) up to 32GB HFS+ formated (Mac OS 8.1, 9 or early Mac OS X).

Note: Please be patient when extracting these blank disk images, as your hard disk has to write the whole space (up to 30GB) so it might take a couple minutes depending on your computer specs.

HFS vs HFS+ quick tip from that-ben: Even tough HFS standard is highly compatible with almost all Mac OS versions, it still remains the worst choice for any Mac OS 8.1 or 9.x setup in terms of efficiency. The reason is the bigger the hard drive in standard HFS (not HFS+) is, the larger small files will use. For instance, think of a 30GB drive that you format as HFS standard. Just a couple characters typed in a SimpleText document and saved on that drive will always result in a minimum size of nearly 1MB (1000000 bytes) instead of say, 8 bytes! This is due to the 16-bit blocks addresses limitation. The way HFS standard was implemented, there can only be limited small amount of blocks on a single drive, resulting in those blocks to distribute the hard drive space evenly and thus, be huge. Even if you write tiny files, the remaining bytes in those blocks are totally wasted, resulting in humongous files that contain next to no DATA. In other words, if you're planning on using, say more than a 10GB big drive in Mac OS 9, you should totally go with HFS+ as it will contain WAY MORE files than a same size HFS standard drive.

Compatibility notes

Those are blank disk images, compressed. On Windows, you can use WinRAR or WinZip to extract them. On Mac OS X, you can use The Unarchiver.



These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

  • Use the dd command as a parameter of the sudo command to write the ISO image to the flash drive: # sudo dd if=/path/to/image.iso of=/dev/rdisknumber bs=1m Mac OS X provides both a block (/dev/disk.) and character device (/dev/rdisk.) file for each storage device.

Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
    Catalina:*
    Mojave:*

    High Sierra:*
    El Capitan:
  4. Press Return after typing the command.
  5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
  7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the command for El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

  1. Plug the bootable installer into a compatible Mac.
  2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
    Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
  3. Choose your language, if prompted.
  4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
  5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.
