Q: Your bootable USB drive could not be created, BCA 6, OS 10.11

Hello, I'm trying to make bootable USB drive in order to instal W10. I keep getting the same error:

"Boot Camp only supports Windows 7 or later installation on this platform. Please use an ISO file for Windows 7 or later installation."

I'm running OS 10.11 fully updated, BCA 6. The W10 is x64. The USB drive is 64GB.

My MacBook Pro is a Retina, Mid 2012 and all the specs are fall into the recommended.

What could be happening?

MacBook Pro with Retina display, OS X El Capitan (10.11), Mid. 2012

You may need a developer account, but try using your AppleID first.

1. Disconnect all external storage.
2. Run SMC/NVRAM reset.
3. Use a Wired connection if you plan to download Windows Support Software or if it is automatically checked for you.
4. Do not use an external USB HDD for the Windows Installer. You must use a USB2 flash drive (USB3 may not work on older models).
5. Please test and report any issues.

In OPs case, despite the recommendation to disconnect the external disk, the Seagate did not seem to be disconnected during the build.

1. You should unmount the Windows 10 ISO image.
2. Your USB looks correctly formatted.
3. Use a Wired connection, if possible, when building the USB. The Support Software download is faster and more reliable.

In Disk Utility, if you click on the Image, and click on Unmount, it should unmount the image. You can also use diskutil eject from the Terminal.

diskutil eject disk3

The syntax for the Terminal command is

diskutil eject

Usage: diskutil eject MountPoint|DiskIdentifier|DeviceNode

It's MacBook Pro (Retina, 15-inch, Late 2013).

Is this correct?
