Creating an OS X Yosemite USB Installer Using UniBeast: A Step-by-Step Guide

=====================================================================================================

Introduction

----------

Since Apple has retired its traditional method of creating a bootable OS X USB installer due to security concerns and changes in the latest operating systems, users are left wondering how they can still achieve this essential task. Fortunately, there is an alternative approach that works perfectly well with OS X Yosemite: using UniBeast.

In this article, we will walk you through the process of creating a bootable OS X 10.10 Yosemite USB installer for your Mac or Hackintosh computer running either Mavericks (or later) or Mountain Lion (with some modifications).

Prerequisites

----------

Before proceeding, make sure that:

1. You have an Intel-based Mac or compatible Hackintosh system.

2. Your target drive has at least 8 GB of free space available.

Software Requirements:

-------------------

To successfully complete this guide, you will need to download and install the following software:

* UniBeast v3.9.x (or later) for Mavericks (10.9+) or Mountain Lion (10.8+)

* The Yosemite Installer .dmg file from Apple's App Store

* An empty USB drive with at least 16 GB of free space

Step-by-Step Instructions:

----------------------------

### Step 1: Download and Install UniBeast

Download the latest version of UniBeast that matches your operating system (Mavericks or Mountain Lion) from 'here'(http://www.tonymacx86.com/).

Double-click on the downloaded .zip file to extract its contents. Open Terminal, navigate into the newly created directory using `cd`, and then run either:

```bash

./UniBeast.app

```

for Mavericks (10.9+) or

```bash

./UniBeast_2.x.y.app

```

### Step 2: Format Your USB Drive

Insert your empty USB drive that has at least 16 GB of free space into an available port on your Mac.

Launch Disk Utility by pressing Command + Spacebar and typing 'Disk Utility'. Click 'Continue' when prompted to allow the app to access this location. Select the target volume, click Erase tab > Quick erase button (or Secure Erase if you want extra security), then Quit Disk Utility once complete.

### Step 3: Download Yosemite Installer

Launch Safari or any other web browser on your Mac and navigate 'here'(http://support.apple.com/kb/DL1534). Sign in with your Apple ID & password when prompted. Once the download completes, click 'Install' to begin installing it onto /Applications/ folder.

### Step 4: Create Bootable USB Installer

Launch UniBeast.app from Applications directory by double-clicking on its icon or typing `./UniBeast` if you can't see it there because of Gatekeeper restrictions. Select your Yosemite .dmg file as the base image under 'Output', select your newly formatted USB drive as destination, then click 'Continue'.

Wait for UniBeast to finish creating a bootable OS X 10.8 or later installer on your external hard drive; this may take several minutes depending upon system specifications.

### Step

Insert the completed .dmg file onto an optical disc (if you still have one) and reboot from it by holding down Command + Option keys during startup until you see 'Boot' in lower left corner of screen. Follow instructions displayed onscreen to complete installation process.

Troubleshooting

--------------

If, after following these steps precisely but still encountering issues like 'No eligible packages found' error message while running Unibeast 6.x series:

1. Ensure that your Mac's System Preferences > Security & Privacy has 'Allow apps downloaded from anywhere' box checked.

2. Re-download fresh copies of both UniBeast and Yosemite .dmg files from official sources mentioned above.

-------

With these simple steps, you should now be able to create a bootable OS X 10.8 or later USB installer using UniBeast on any supported Mac running Mavericks (or Mountain Lion with some modifications). This method bypasses the traditional methods that no longer work due to Apple's security changes in Yosemite and El Capitan.

Remember always download software from trusted sources, such as TonyMacX86's website for the latest versions of UniBeast.
