Note: If you have a Mac with T2 Security Chip (that is, Macs introduced in 2018 or later), first follow this guide to allow booting from external media. After you create the bootable USB drive, the process to install it is simple. Make sure the USB drive is connected to the Mac. Next, click on the Apple logo from the top left and choose Restart. Use the Restore Disk Image to Drive dialog box to browse for the DMG file with the installation files for Mac OS X Yosemite in this case, and click the OK button to create a bootable USB of the operating system. Now, you’ll have to wait a long time.
- Bootable USB installers offer an easy way to upgrade multiple Macs to macOS Catalina, to perform clean installs of MacOS Catalina, to perform maintenance from a boot disk like formatting disks, modifying disk partitions, and performing restorations, and much more. We’ll walk through how to create a boot USB install drive for MacOS Catalina 10.15.
- The media creation tool mentioned previously can also write a downloaded ISO file to a USB drive in one go, and so create a bootable USB – but it only works with Windows 10. There are, though, many freeware programs suitable for all operating systems (including Linux) that can take over the tasks of the otherwise manual device management.
- Image via arstechnica.net Step 4: Drag your USB (or a Dual-Layer DVD) drive from the list on the left into the 'Destination' box and click 'Restore' (or just click the 'Burn' button in the upper left if you're using a Dual-Layer DVD) and in 10-30 minutes (depending on whether you're using USB 2.0 or 3.0) you'll have your backup disk ready to instal on as many Macs as you like.
In the category of “tools that can save an ill Mac,” there are few that are more important than a bootable macOS installation USB stick. Whenever I go on a business trip, I make sure I have a couple of these packed in my carry-on luggage. On more than one occasion, this tool has saved the trip from disaster.
Your Mac won’t boot? This tool is the first thing to try. You’ve done something by mistake, and your Mac is now unstable? This tool can fix it. (Yes, this did happen to me when I was on a business trip to Japan. I will spare you the gory details.)
It used to be rather challenging to create such a tool, but then a wonderful utility appeared: DiskMaker X. Developed by a lone programmer, Guillaume Gète, DiskMaker X quickly became (and continues to be) the best utility to create a bootable macOS installation USB stick. All you need is:
- DiskMaker X
- A macOS installation app (such as the “Install macOS Mojave” app from Apple)
- 8 GB USB thumb drive
Run DiskMaker X on your Mac, point it to the macOS installation app and insert the USB stick. A few minutes later, you’ll have a bootable installation USB stick for that version of macOS.
Along the way, you’ll see progress notifications of “DiskMaker X 8 for macOS Mojave”

When you hear DiskMaker roar (No kidding! There actually is a roar at completion!), you’ll see macOS Mojave downloading.
Run into any problems? Just check the FAQ that Guillaume maintains or send him an email. It’s one of the best-supported shareware apps I have ever encountered.
If you had asked me last week if it was possible to create a bootable macOS installation USB stick on a Windows PC, I would have immediately answered no. However, in a feat of technical wizardry, this has been accomplished.
Mauro Huc details in Pureinfotech how to create a bootable macOS USB stick on a Windows 10 PC. The process is not as seamless as DiskMaker X, but that it’s possible at all is simply amazing.
This must be the week for creating a bootable macOS USB sticks on non-Apple devices, since a question just appeared on Quora asking if this can be done on an Ubuntu Linux PC. No answer to this question yet, so we will have to wait and see if someone knows how to do this.
