With quite 65 million users—consumers, scientists, animators, developers, system administrators, and more—OS X is the most generally used UNIX® desktop operating system. Tight integration with hardware—from the sleek MacBook Air to the powerful Mac Pro—makes OS X the platform of choice for an emerging generation of power users. How to Install OS X macOS Sierra On PC With Windows, Without Mac There is no use of MAC Computer, you will need only Windows PC. And One USB flash Drive. It’s very simple and easy. In Windows Create a Virtual Machine of macOS Like El Capitan or macOS Sierra.

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.

Download macOS

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

  • macOS Catalina, macOS Mojave, and macOS High Sierra 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.
    To get the required 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.
  • macOS Sierra downloads as a disk image that contains a file named InstallOS.pkg. Open this file and follow the onscreen instructions. It installs an app named Install macOS Sierra into your Applications folder.
  • OS X El Capitan downloads as a disk image that contains a file named InstallMacOSX.pkg. Open this file and follow the onscreen instructions. It installs an app named Install OS X El Capitan into your Applications folder.

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:*
    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 commands for Sierra and 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.

mkisofs is used for premastering iso9660 filesystems which are used on CDROMs. The output of mkisofs can then be sent to a CDROM writer with a utility such as cdrecord. It has support for many formats, including Rock Ridge, Joliet, and Apple HFS (beta).

Mac aurora hdr torrent. Including common files in multiple CD's
Greetings,

I'm trying to burn a bunch of data to multiple CDs while including a few 'common files' on each ISO. (Like a common README file)

Is it possible to do this without doing the ISO segmentation (CD1, CD2 ..) manually?

Any advice would be greatly appreciated!

Thanks

No more updates to mkisofs
mkisofs will not receive more updates as a stand-alone program, but it can be found inside cdrecord project (http://freshmeat.net/projects/cdrecord/).

Multiple El-torito?
How does this work?
How does your bios determine which image to boot from?
Very interesting but considering there is very little documentation (went to site, viewed man pages) it doesn't seem all that usefull..yet.
