How to create a bootable OS X Yosemite drive! You can perform clean installations easily and install this version of OS X on other Macs!Sudo Command:sudo /Ap. There are times when you may want to avoid using App Store or the built-in recovery mode to install OS X 10.10 Yosemite. So, Apple continues to give you the option of creating a bootable USB drive.

  • Jun 05, 2014 Apple released the new Mac OS X 10.10 Yosemite in the Mac App Store for everyone to download and install for free on October 16th, 2014, but downloading a 5+ GB file for each of your computers will take some serious time. The best thing to do is download it once and create a bootable install USB drive from the file for all of your Macs.
  • Mac OS X Yosemite is available for free from the Apple iTunes store. If a Mac computer has the hardware to run Mac OS X Mavericks, then it also has the hardware necessary to run X Yosemite, with the exception in some circumstances being that some Mavericks machines do not have WiFi for the Continuity feature, which allows users to pick up where they left off using any of their Apple products.

Which mac are you wanting to download Mac OS X Yosemite on, model and year.

Some macs that came preinstalled with an OS newer than Mac OS X Yosemite cannot

do the conversion from InstallOSX.pkg to Install OS X Yosemite.app.


If the 'donor' mac is too new to convert the InstallOSX.pkg to Install OS X Yosemite.app

do you have a copy of the Snow Leopard DVD install disk.

Go to Download macOS and click on OS X Yosemite 10.10

this downloads InstallMacOSX.dmg to your Downloads folder.

The next section can only be done on a mac that is capable of running Yosemite.

This includes macs that have the potential to run Yosemite but have been upgraded to a newer OS.

A mac that came preinstalled with an OS later than Yosemite will refuse to do the next bit.


When downloaded open to InstallMacOSX.pkg, double-click on

that and an installation window will open, this does not install Yosemite

but converts the InstallMacOSX.pkg to the Install OS X Yosemite.app which

you will find in your Applications folder.


(If the installation window asks which disk you want to install to, you must pick

the disk that you are booted to at the time. Not any internal or external disk that

you want to eventually install Yosemite on, that is for later.)

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.

What you need to create a bootable installer

  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14 GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra or El Capitan

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave or macOS High Sierra
    These will be downloaded to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. 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.
  • Download: OS X El Capitan
    This will be downloaded as a disk image named InstallMacOSX.dmg. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It will install 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

Creator
  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  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 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.

Big Sur:*

Catalina:*

Mojave:*

High Sierra:*

El Capitan:

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

After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume has been erased, you may see an alert stating that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's been completed, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
