Create OS X Lion Bootable USB: Step-by-Step Guide
If you're a Mac user looking to create a bootable USB drive for OS X Lion, you've come to the right place. While it may seem like a complex task, we've simplified it into a step-by-step guide that will have you creating your OS X Lion bootable USB in no time. Let's dive right in!
Before we start, make sure you have a USB drive with at least 8GB of space, a Mac running OS X Lion, and the OS X Lion installer app downloaded from the Mac App Store.
Preparing Your USB Drive
First things first, we need to prepare your USB drive for the installation. This involves formatting the drive to Mac OS Extended (Journaled) and partitioning it into a single volume.
Here's how to do it:
Format the USB Drive
Insert your USB drive into your Mac. Open Disk Utility, which you can find in Applications>Utilities. Select your USB drive from the left sidebar and click on the "Erase" tab. Name your drive "OS X Install", select "Mac OS Extended (Journaled)" as the format, and "GUID Partition Map" as the scheme. Click "Erase" to format your drive.

Important: This will erase all data on the USB drive, so make sure to back up any important files first.
Partition the USB Drive
After formatting, select the drive again and click on the "Partition" tab. Here, you'll see a simple layout with the name of your drive at the top. Click the "+" button to add a new partition. Name this partition "OS X Base System" and set the size to 800MB. Click "Apply" to save these changes. This partition will hold the bootloader that will allow your Mac to boot from the USB drive.
Install the OS X Lion Installer on the USB Drive
Now that our USB drive is ready, let's install the OS X Lion installer onto it. Open the Terminal app, which you can find in Applications>Utilities. To simplify things, we'll be using a command line tool called "createinstallmedia".
First, we need to close the Finder, which we can do by typing "killall Finder" into the Terminal and pressing enter. Then, mount the OS X Lion installer by typing the following command and pressing enter:
```bash sudo /Volumes/MAC\ OS\ X\ Install/mountosx -applicationpath /path/to/your/Install\ mac\ os\ X\ lion.app folder -convertmode ultrawide -volpath /Volumes/OS\ X\ Install touchdown ```
