Is @EricFromCanada's fix legitimate? Does it work? I just tried again today to make a bootable usb thumb drive for macOS Sierra.
I tried the creatinstallmedia terminal method, and I get the invalid mount error.
I have the IntallOS.dmg downloaded from apple site (how to get old versions link), and it is 5.01GB. How do I get this working?
Thanks.
