Yosemite

Its been a week now since Apple released OS X Yosemite Developer Preview and with all the new features and specially the overhaul in the design, there’s no point for users like me to not to test the build. Unfortunately, I couldn’t update to OS X Yosemite because of Hackintosh problems but if you’re a Mac user or have a decent Hackintosh setup, you can easily upgrade to Yosemite Developer Build without any problems.

One way of upgrading is to install OS X Yosemite over your current installation, which is not at all recommended as Yosemite is currently in unstable stage, and even if significant number of the things are working in Yosemite, you should not install it over your current setup. The other way for testing OS X Yosemite is create a new partition on your Mac or use an external drive and install OS X Yosemite in the new partition, this way, you’ll have access to Mavericks as well as Yosemite and you can get rid of the Yosemite partition anytime after testing.

Either way, you’ll need the OS X Yosemite app which you can download from your Apple Developer account or from Apple Beta Seed program site if you have signed up earlier. But, for installing Yosemite on an external drive or a different partition of your Mac, you’ll need a bootable USB of OS X Yosemite.

You can create bootable USB installer for Yosemite using the traditional method which involves complex steps like mounting different images and copying the contents manually to the USB drive. But, there’s also a simpler way of making Yosemite installer. There’s a tool called MacPwn which simplifies the process of creating bootable USB for Yosemite.

Before getting started, just plug-in the USB drive and then open Disk Utility from Utilities folder. Now select the USB drive, move to partition tab, select 1 Partition from the drop-down and click on “Options” button at the bottom and select “GUID Partition Scheme” option. Once done, format the USB drive.

You can download MacPwn here. To create the USB installer, you just need to have the OS X Yosemite Developer Build app file in your Applications folder, and then you need to start the MacPwn app. MacPwn is basically created for Hackintosh based installations, but it works for real Macs too. Once you open the app, follow the screen. When you’re asked to select the Destination, select the USB Drive(should be at least 8GB) which you want to make the installer and you’ll reach a screen with “Customize” button at the lower left, you need to click on that and uncheck all the options, because those are for Hackintosh installations. So, once you uncheck everything in the Customize screen, you just need to finalize the setup and it will start creating your USB. It will take some time as it will do all the steps automatically, and it will also notify you through Notification Center notifications. Once done, you can use the USB to install OS X Yosemite anywhere.

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 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Create Yosemite Usb Installer On Windows

Download macOS

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download 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 downloads 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 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.
  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 is erased, you may see an alert 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 done, 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.
