I really like Manjaro and have used it on my laptop.
On my iMac 27" 2011 with faulty AMD card, I have MX Linux 21 installed and running.
When i run from manjaro live usb, I get a black screen and grub menu is not visible. I have used different usb makers like balenaetcher, fedora writer and mxlive usb maker and had the same result.
As i cannot see the grub menu, cannot choose failsafe options.
Any help is greatly appreciated.
Below is system information.
