How to Create Bootable macOS Catalina USB Install Drive

To proceed, you will need a USB flash drive and it’s always better that you get a drive with a USB-C connection. Because that is what most of the MacBooks have it in their ports. 

Pro Tip: Make sure that the USB flash drive which you’re going to use in this procedure has at least 16GB of space and it must be formatted completely before getting started! 

So you can get a USB-C flash drive from Kingston or UGREEN. Any one of them is good to go! Let me now walk you through the steps!

Step #1. If you’re a developer, you can download the developer beta version from here and if you’re looking for a public beta, you can get it from here. Meanwhile, once the final version of macOS Catalina is launched, you can download it directly from the Mac App Store. 

Step #2. Once the macOS Catalina is downloaded on your system, the installer will be launched which you need to close it right when it pops up!

Step #3. Now head over to Finder → Applications → right-click on Install macOS Catalina Beta & click on Show Package Contents. Next, open Contents followed by Resources

Step #4. Launch the Terminal window by following this path, Applications → Utilities → Terminal. Once opened, type sudo with space. In step #2, you’ve opened resources in which you need to drag createinstallmedia to the terminal window. 

Step #5. Now type _-Volumefollowed by a space in the terminal window once you’ve dragged createinstallmedia. 

Step #6. Head over to Go To Folder via Finder → Go → Go To Folder. In go to folder, type /Volume and click on Go. 

Step #7. Now insert your USB flash drive on your Mac and it will now appear in the Finder window within seconds. Next, drag the USB flash drive into the Terminal window. 

Step #8. Press Return key on the keyboard to initiate the process and to submit full command. Enter the password when it asks in the terminal window. 

Step #9. Now type Y when it asks to in the Terminal window and press Return key again on the keyboard. 

Step #10. Once done, it will remove all the existing files in USB flash drive if any and it will then install the installer files into the USB flash drive. 

The overall process would take some time to complete. Ensure that you do not press anything on your Mac until the process is completed. Once done, your USB flash drive is successfully booted with macOS Catalina 10.15!
