No install on MacBook PRO 2011

Newly created Manjaro-KDE stick from newest downloads:

Stick can be selected as an EFI install media and the LED on the stick signalizes work.
But the display remains without any output.
Alternatively burned the Manjaro ISO an a DVD, DVD works and You hear the accesses … but NO screen output visible after some minutes

Same stick with newest EndeavourOS installed boots flawlessly. Any hints for me?
