Install manjaro on Macbook Pro late 2011

I tried to install manjaro 20.1 gnome edition on my old macbook pro late 2011 (8.2 version).
Unfortunately after burn the iso on a 4G usb stick the macbook doesn’t seem enable to boot grub.

Before I booted and installed successfuly Ubuntu 20.04.

Any suggest?

This should definitely help

nope, the boot hang before to show the screen with grub.
I can not modify any parameters.
This is very strange because another usb stick with ubuntu 20.04 work fine.
