Mac Osx Boot Disk Iso Download

In order to do this, we first need to create a bootable USB drive which has been. On Linux and OS X, you can use the dd command, which is pre-installed on those. Once you've downloaded and verified your Kali ISO file, you can use the dd.

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 install macOS, but it can be useful when you want to install macOS on multiple computers without downloading the installer each time.

Download macOS

  1. Download a macOS installer, such as macOS Mojave or macOS High Sierra.
    To download macOS Mojave or High Sierra for this purpose, 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.
  2. When the macOS installer opens, quit it without continuing installation.
  3. Find the installer in your Applications folder as a single ”Install” file, such as Install macOS Mojave.

Use the 'createinstallmedia' command in Terminal

  1. After downloading the installer, connect the USB flash drive or other volume 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 accordingly.
    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 Mojave. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument. The Sierra and El Capitan commands show the proper format of this argument.

Disk

Use the bootable installer

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

  1. Connect the bootable installer to 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.

Two points.
  1. Remember, until the Mighty Mouse, standard Mac mice only had one button. The 'right click' convention is very new to olde-tyme mac users (and I would wager, Mac developers as well). The olde-type mac convention is the good ol' 'click-and-drag'.

    Now, correct me if I'm wrong, but can you not simply download the iso, pop in your blank CDR, drag the iso image to the CDR icon, and click 'burn'?

    Don't get me wrong here, I'm not trying to mock the 'switchers' out there who assume it's more complicated than that because the OS they're used to (Windows) makes it more complicated. After all, the whole reason I found this thread is because I too assumed it would be more complicated (I switched from Mac to PC a few years back due to work requirements, and am only now switching back. I'm having to 're-learn' some of the intuitive functions of the Mac).

    In fact, I haven't tested the 'click-and-drag' approach yet because I followed the disk utility method in the first post of this thread.

    Still, I'd be very surprised if the 'click-and-drag' method doesn't get the job done. After all, it's the way Macs have worked since 1984.

  2. There's no real such thing as a 'bootable cd' in Mac terms. If your CD (or floppy) has a full version of the OS on it, it'll boot. To boot from CD, you have to hold down the 'C' key on your keyboard at startup. That's been the convention since at least OS 7.6.1 (that was the first OS I used with a CD rom. Booting from floppy in OS 6 on my Mac Classic didn't even require holding down the 'C' key).

ASIDE: Not until this year have I had the opportunity to explain olde-tyme Mac conventions to PC 'switchers'. I have to say, it feels really nice to be explaining the quirks of my OS to them for a change, rather than having to ask them how to perform the same tasks in Windows.
