new final released (3 december) this has been fix.
but chameeon still wont boot up. we need to boot into clover instead.
right after you choosing your usb stick for boot up, press 6 in keyboard.
it will load clover, it will give and option to continue or choose boot option,etc etc.
i choose boot option and i choose boot with EFI. now apple logo should pop out.
this work for me, you can playing around with the option if my option doesnt work. cheers!
