How to create a macOS Sequoia bootable USB for installation on Windows 10 PC?

I used UltraDMG to create a macOS bootable USB on Windows, and it worked like a charm for reinstalling macOS Sequoia on my MacBook Pro. Highly recommend it!

P.S. To save time during dmg burning and macOS installation, it is recommended using a USB 3.0 or above USB flash drive instead. macOS Sequoia is quite big and it could take hours to install on a slow USB 2.0 drive.
Anastmsia A bootable DMG file is a disk image file created for macOS that contains an installation of an operating system or other software, and is set up in such a way that it can be used to boot a Mac computer. The ".dmg" extension stands for "disk image," which is a file format used to package and distribute applications and files on macOS.
To use a bootable Sequoia DMG, you typically need to either burn dmg file to a USB drive or a DVD or mount it during the boot process. This is the simple to make a macOS Sequoia bootable USB on Windows. You can then choose the bootable drive to start the installation or recovery process.
