Creating a bootable drive for your Mac certainly seems to be a wise decision to make. Even though the macOS recovery partition can take care of all your recovery requirements in times of need, it’s still worthwhile to have a bootable installer.
Why Do You Need to Create A Bootable Drive For Your Mac?
- The Mac installer gets deleted as soon as you download it and use it by installing the Mac operating system. Once the installer gets deleted, it means that you can no longer use it to install the macOS on another Mac device. You will have to again download the installer on the latter Mac to install the macOS. This can take a lot of time and become inefficient if you have multiple Macs.
- Clean installs can be performed by installers which are very helpful in overwriting your start-up drive. You can also use this function for other troubleshooting issues as well.
- When you have a bootable installer, it ensures that you are well guarded in an emergency scenario by making use of some of its helpful utilities.
- A bootable installer can allow you to install an earlier version of macOS and also let you temporarily boot into the previous version of the macOS.
What Do You Need Before Creating Your Bootable Drive?
Before you begin the process, you will need the following:
- USB Stick / External Hard Drive: If you are planning to use a USB for downloading the bootable version of the installer, make sure that it is 8GB in size or larger than that. In the case of Sierra, 12GB is recommended as the minimum requirement. Ideally, 32GB to 64GB is a good size to have as it is not only cost-effective but also gives a better performance. In the case of an external drive, you can use any spare one that you are not going to use for any other work.
- Download macOS High Sierra Installer: It is important to note that once you have downloaded the installer, it will begin with the installation process on its own. You can close the installer just like you quit any Mac app. In the case of the macOS version being older than the current one, you can click on ‘ok’ once the message flashes that the version is too old to install. You can find the old installer file in your ‘Application Folder’. Don’t forget to take a backup of your Mac to be on a safe side.

Create Bootable Usb Drive For Mac Os X
I had a guy bring me in an old Mac Book Pro that had a corrupted hard drive. I saved his Data but then realized his computer was so old that I was going to have trouble getting a copy of OSX installed. His computer was no longer supported on current OSX releases. To make things worse his DVD drive wouldn't read a install disk. So this post is the result of me finding a way to resurrect an old Mac Book Pro. I hope it will help someone else in a similar situation.
Note:
Before starting this tutorial, ensure that you have a USB drive with at least 8GB of storage as well as a Leopard, or Snow Leopard retail DVD or disk image. Grey DVDs that were included with a Mac at the time of purchase cannot be used to make USB boot drives as they do not include drivers for Macs other than the computer it was shipped with. In this tutorial I will be creating a Snow Leopard USB install disk. The steps are the same to create one for Leopard.
Creating a Snow Leopard USB Boot Drive Using Disk Utility
Start by launching Disk Utility on the Mac. To do this, you can either search for the application in Spotlight or find it in the Applications folder. Locate the USB drive on the left-hand side of the window and click on its name, not its partition.
Format the USB drive
- Click the Partition tab
- Under the Partition Layout header click on the 1 Partition option in the drop-down menu
- Click the Format drop-down menu and select Mac OS Extended (Journaled).

Bear in mind that this will erase all data from the USB drive, so backup any important files before proceeding.
- To format the USB drive drive, click the Apply button in the lower right-hand corner of the Disk Utility window.
Snow Leopard, DVD or Disk Image
- Locate a Snow Leopard disk image or DVD on the Mac
- If you're using a disk image, mount it to the desktop
- In the Disk Utility window, click the Restore tab in the USB drive's menu
In the center of the window you'll see two boxes: one labeled Source and another Destination.
- Drag-and-drop the USB drive's partition into the Destination box
- Drag-and-drop the Mac OS X Install Drive disk into the Source box
- At the bottom right-hand corner of the screen and click the Restore button
Disk Utility will restore the OS X Install DVD or disk image to the USB drive; this process may take anywhere from 20 minutes to an hour depending on how quick the Mac is.
Using The Snow Leopard USB Drive
Now that you've created a Snow Leopard USB drive, let's use it to install OS X Snow Leopard as well as access Terminal, Disk Utility, and other OS X utilities.
- Power down the Mac and reboot while holding the Option key
- Select the OS X Install DVD from the boot menu using the arrow keys on the Mac's keyboard
- Select the language you'd like to use when prompted
Installing OS X Snow Leopard
To install OS X Snow Leopard from the USB drive, you'll need to reformat the Mac's hard drive. To do this, look towards the top of the screen and click on Utilities from the top menu and then click Disk Utility from the drop-down menu.
Formatting The Mac's Hard Drive
- Click on the Mac's hard drive name
- Click the Erase tab
- Select Mac OS Extended (Journaled) from the Format drop-down menu
- Name the drive whatever you'd like
Please note that all data on the Mac's hard drive will be erased, so backup all important files before proceeding.
- Press the Erase button to format the Mac's hard drive
Starting The Snow Leopard Installer
- Quit Disk Utility by pressing Command-Q on the keyboard
- Press the Continue button
- From the center of the window, select the Mac's hard drive
- Press the Install button
OS X Snow Leopard may take a bit of time to install depending on the Mac's hardware. Upon completion, the Mac will restart and prompt you to create an account.
Disk Utilities on the Snow Leopard USB Drive
Additionally, you can access Disk Utility, Terminal, Safari (to access Apple help articles. not general browsing) and other Mac utilities from the Snow Leopard USB drive.
Boot the Mac to the USB drive using the steps shown above and click on the Utilities button from the top bar. You can access all available utilities from this drop-down menu.
It's nice to have these utilities available to use from the USB drive, especially Disk Utility. For example, if you believe your hard drive has died or is corrupted, you can boot your Mac from the USB drive and use Disk Utility to check the the hard drive's SMART status and repair said drive.
OS X Snow Leopard USB Drive, Completed
In this tutorial, I've shown you how to create a bootable OS X 10.6 Snow Leopard USB drive. You can now use the USB drive to upgrade, maintain and restore Macs to OS X 10.6.
