A macOS Catalina USB install drive is a great tool to have on hand to for quick and easy macOS 10.15 reinstalls. We show you how in this video tutorial.
Download Install Disk Creator by clicking on the link. When the download is done, you can move it over to your Applications folder. Then follow these steps to create your bootable macOS Catalina. Fortunately, there's a great tool that you can use for free to create bootable macOS media on a USB drive in a Windows 10 environment. This article shows you how to download a macOS DMG file, format a USB drive using a GUID Partition Table, burn the DMG to the drive and boot your Mac from the USB. If you have more than one Mac you want to upgrade to macOS 10.15 Catalina but don't want to waste so much bandwidth downloading it for each machine, one option is to create a bootable installer on.
Helps you create a bootable USB drive for macOS Catalina which will work with older Macs, not officially supported by the operating system
What's new in macOS Catalina Patcher 1.4.4:
- Fixed compatibility with Catalina version 10.15.5
macOS Catalina Patcher (formerly macOS Mojave Patcher, macOS High Sierra Patcher and macOS Sierra Patcher) is a small yet powerful tool that can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012, basically acting as a macOS Mojave patch for unsupported Macs.
The tool extends the list of compatible hardware to the Mac Pro, iMac and MacBook Pro computers released in early 2008, Aluminum Unibody MacBooks or MacBooks Air manufactured in late 2008, or white MacBooks and Mac Minis produced in early 2009.
Get the macOS Catalina Installer app and make sure you have access to a compatible USB drive
To be able to use the app you must make sure that you have a USB drive that has at least 8 GB available, and that you have the macOS 10.15 Catalina installer app on your Mac.
Note that you can download the macOS image from the Mac App Store application only on a machine that supports Catalina: otherwise, you must find an alternative solution.
For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu.
At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.
Easy to configure patcher tool that can create bootable macOS Catalina USBs
Within the main window, you must simply load the macOS 10.15 image you want to use and select the target USB drive. The app will verify the image to make sure everything is OK, and all you have to do is press the Start Operation button.
You have the option to monitor the process in the macOS Catalina Patcher main window, and the utility lets you know when the task is complete.
Worth mentioning is that after you install the OS by using the macOS Catalina Patcher bootable drive, you must launch the macOS Post Install utility to get access to patches specifically designed for your Mac’s model.
Make a bootable drive that allows you to install Catalina on unsupported Macs
Bottom line, if your Mac has been manufactured before early 2008, chances are that you will not be able to install macOS Catalina on your computer.
All things considered, macOS Catalina Patcher is a small and user-friendly utility designed to help you bypass this limitation if your Mac is not in macOS Catalina's compatibility list, created to be used as an unsupported Mac Mojave patch.

An external drive that you can use as an installer for macOS Catalina is a handy thing to have. If you have multple Macs to upgrade, it’s a lot more efficient to plug in the USB installer drive and run the installer than to log into the App Store, download the 8.09GB OS installer, and then run it.
In this article I’ll go over the different ways you can create a bootable macOS Catalina installation drive. But before I give instructions on how to create the drive, I’ll go over the items you’ll need and how to get them.
Get an external drive and maybe an adapter
The macOS Catalina installer software is over 8GB, so you need a USB external drive that can hold that much data. The drive can be a thumb drive, hard drive, or SSD.
If you have a 2015 or newer MacBook or a 2016 or newer MacBook Pro, you may need Apple’s $19 USB to USB-C adapter. This will allow you to connect a storage device that uses a USB type-A connector. If you don’t have an external drive and you have a USB-C Mac laptop, you could buy the SanDisk Ultra USB Type-C Flash Drive, which has a USB-C connector. You can get model number SDCZ450-016G-G46.
When creating the boot drive, the storage device is reformatted, so there’s no need to format the drive beforehand.
Get the macOS Catalina installer software
The macOS Catalina installer is available in the App Store. If you launch the App Store app, do a search for “Catalina.” Or, if you click this Catalina App Store link, it will take you to the Catalina App Store webpage, then click on the “View in the Mac App Store” button.
You can read the information to learn more about Catalina. When you’re ready to download the software, click the Download button. (If you’ve already downloaded the installer, the button will say Install instead of Get.)
Once the download is complete, the installer will launch automatically. But don’t continue with the installation. Instead, press Command-Q on your keyboard to quit the installer.
The Catalina installer app will be in your Applications folder, so you can go there and launch it later to upgrade your Mac to the new operating system.
Make a bootable installer drive: The quick way
I used a free app called Install Disk Creator to make the installation drive. Download Install Disk Creator by clicking on the link. When the download is done, you can move it over to your Applications folder. Then follow these steps to create your bootable macOS Catalina drive.
1. Connect your drive to your Mac.
2. Launch Install Disk Creator.
3. In the main window, you’ll see a pop-up menu under Select the volume to become the installer. Click on the menu and select your drive.
4. Under the pop-up menu, you’ll see Select the OS X installer. (macOS used to be called OS X.) If you have only the Catalina installer on your Mac, Install Disk Creator will automatically select it. If you have other macOS installers, you need to click on Select the OS X installer and select the Catalina installer.

5. When you’re ready, click Create installer. Your Mac may tell you that Install Disk Creator wants to make changes, and you need to enter your user name and password. After you do this, the app will take a few minutes to create the boot drive. A progress bar. appears at the bottom of the Install Disk Create window.

If you try to start the process and you get a failure message saying that the drive couldn’t be unmounted, try reformatting the drive first as ExFAT using Disk Utility. Then start the process over again.

When the app is done, the installer is ready to use.
