Unable to get the iMac to boot from a usb drive
I’m trying to wipe my Late 2015 Intel iMac using DBAN. I have been unable to get the iMac to boot from a usb drive. I used dban_2.3.0.iso to create a supposedly bootable usb drive from the ISO file. The contents of the usb drive are shown below. I can’t get the iMac to boot from the drive. Any help,would be greatly appreciated.
Thanks,
Phil
