+# First, we need to find our device. BEFORE inserting your USB drive, run the
+# following:
+diskutil list
+
+# This will output a bunch of info about all of the disk drives connected to
+# your Mac. Each entry will have a header in the form "/dev/diskX", where X is
+# some number starting at 0. Now, insert your USB drive and run the command
+# again. You should see a new entry. Make note of the name (ie, /dev/diskX).
+diskutil list
+
+# Now we need to format the drive for MS-DOS and include a Master Boot Record.
+# In the command below, replace "diskX" with the identifier of your USB drive.
+# WARNING: this will delete everything on the USB!!
+diskutil eraseDisk MS-DOS WIN10 MBR diskX
+
+# In the command above, MS-DOS is the format of the partition that will be
+# created on the USB. WIN10 is the name of that partition (it'll appear in
+# Finder as the name of your USB). MBR tells diskutil to create a Master Boot
+# Record, which is necessary for the USB to be bootable.
+#
+# Now, "open" the Windows ISO:
+open Win10xxxx.iso
+
+# Your Mac will "mount" the ISO as if it was a drive. A Finder window will open
+# to show the contents of the ISO. Close the Finder window; you don't need it.
+# Back in the terminal, let's find the mounted ISO:
+diskutil list
+
+# You should see a new entry. This time, we're looking for what's in the NAME
+# column. You should see something funny like CCCOMA_X64FRE_EN-US_DV9. The name
+# will differ depending on which ISO you downloaded. Make note of the diskX
+# identifier as well. Now, let's cd to the ISO:
+cd /Volumes/CCCOMA_X64FRE_EN-US_DV9
+
+# And copy all the files over to our USB:
+sudo cp -r . /Volumes/WIN10/
+
+# This will take a while; there's a lot of data (4+ GB). Grab a drink; relax.
+#
+# Once it's done, you can eject both the USB and the ISO. First, cd to another
+# directory otherwise OSX will not allow you to unmount the ISO (since being in
+# the directory means the ISO is "in use"):
+cd ~
+
+# Eject the USB using the diskX identifier from the second step above:
+diskutil eject diskX
+
+# Eject the ISO using the diskX identifier from the fifth step above:
+diskutil eject diskX
+
+# Now insert the USB into your computer, (re)boot, and select the USB from the
+# boot device menu (you may need to press some key to show the boot device menu
+# - on my machine it's F12).
+#
+#Depending on how new your computer is, you may see the USB twice: once with
+# UEFI in front of the name, and the other without. If you see the UEFI option,
+# select that.
