I've been having trouble with this for a long time but never got around to asking for help. Basically, I can never seem to get the dosdude high sierra patcher to create me a bootable USB drive. I have one, in hand, that did work, which is why i've been just living with it, and not stressing the inability to make another. But someday something will happen to my USB drive, and i'll need that new one urgently. I've tried multiple USB drives, USB SSD drives, computers on which i'm creating it, downloading additional ISOs... nothing makes a difference. Is anyone out there able to get it working and if so, how? I've created boot drives with other OSes multiple times and never have any issue. Weird...
