How to Create a Bootable USB Install Drive for Mac Mountain Lion OS

Are you tired of waiting hours for your Mac to download and install the Mountain Lion operating system? Do you want to make reinstalling your OS faster and more convenient? If so, creating a bootable USB install drive is the perfect solution. In this article, we'll guide you through the simple process of creating a bootable USB drive for your Macbook Pro running Mountain Lion.

Step 1: Download the Install File

The first step is to download the 4GB Mountain Lion install file from Apple's website. You'll need an internet connection and a compatible device to complete this step.

Step 2: Insert the USB Flash Drive

Insert the OS DOWNLOAD USB flash drive into your Macbook Pro. Make sure it's empty, as you'll be formatting it later in the process.

Step 3: Open Disk Utility

Hold the CMD key and press the space bar to open Spotlight search. Type 'disk utility' without quotes, then select Disk Utility from the list that appears.

Step 4: Select the OS DOWNLOAD Drive

In Disk Utility, select your OS DOWNLOAD drive on the left panel by clicking on it. This is the USB flash drive you inserted earlier.

Step 5: Partition and Make Bootable

Now we'll partition the OS DOWNLOAD USB drive and make it bootable. You can use an optional 8GB or more Flash drive for a permanent solution, or reuse the OS DOWNLOAD drive. A minimum of 12GB is recommended.

Why Create a Bootable USB Install Drive?

There are two main reasons to create a bootable USB install drive:

2. Convenience: You won't need to download the 4GB file every time you want to reinstall Mountain Lion.
