If you want to install windows 10 aside macOS, just use bootcamp assistant, if not, than I'm not sure.
I have a MacBook Pro M2 running the latest macOS Sonoma. I am looking for a way to make a Windows 10 bootable USB on my Mac so I can fresh install Windows 10 on my newly built PC for my son. Does anyone know know how to do this? In the past, this could be done easily with the stock Built-in Bootcamp Assistant app but it is not available on Sonoma.
[Update Dec 12] The solution that finally worked is WonderISO app. Here is the online tutorial:

P.S. Still received notification from this post frequently. I did try the new suggested app but unable to open it, saying 'WinDiskWriter cannot be opened because it is from an unidentified developer.'
I had this exact question. I just finished using this tutorial and it worked for me.
For those who do not want to watch the video (although highly recommended).
Download the ISO you want to use. Open the terminal (in /Applications/Utilities).
cd /path/to/isoto drive in to folder orcd ..to go back the path.Convert .iso to .img using hdiutil:
hdiutil convert -format UDRW -o /path/to/target.img /path/to/source.isoRename if OS X gave it a .dmg file extension:
mv /path/to/target.img.dmg path/to/target.imgConnect USB drive and type
diskutil listto find the path.Unmount USB drive
diskutil unmountDisk (location of Disk).diskutil unmountDisk /dev/disk2Locate img.
In the terminal, type
sudo dd if=(Full location of img file) of=(location of external USB drive) bs=1msudo dd if=/Users/adames729/Downloads/windows10.img of=/dev/disk2 bs=1mBe patient, it will take about 20-45 minutes.
Once complete, eject by running
diskutil eject (location of USB drive)diskutil eject /dev/disk2
Edit with an additional step needed to make the USB bootable.
This answer needs an update because the latest Windows 10 ISO image is over 5GB, which results in the install.wim in ISO image larger than 4GB. Why this could be an issue? From my test, only FAT32 is supposed to work on Mac. If you want to burn latest Windows 10 ISO, you have to mount the ISO and split the install.wim into small pieces. A lot of online tutorials talking about this.
You can do this with wimlib (split .wim file) and rync (copy files to usb) command to get this done. And there is no need to convert iso to img.
Another possible solution is UUByte ISO Editor (Mac version) , a premium software for creating Windows bootable USB along with other editing features. With the latest update, you don't have to do any additional settings with large Windows 10 ISO. It supports macOS Catalina and Big Sur.
P.S I made a Windows 10 bootable USB on Catalina in less than 2 minutes and successfully installed Windows 10 on my old laptop. My case items:
- Win10_20H2_English_x64.iso (5.73GB)
- macOS Catalina 10.15.5 SanDisk
- SanDisk 32GB USB 3.0 Drive
