Macbook pro boot can't from usb
I created a usb disk for mojave to boot and clean install my Macbook pro 2012 Mid edition.
Each time I press the option key to install from usb, it never comes up with option for the usb to boot instead it just goes to the hard disk option.
Is the usb boot faulty? I bought a new usb disk and tried the same I had the same problem.
Kindly help with a solution.
Thanks
