Startup messages at the key boot before arriving on the Clover interface

[Mackgregor]

Hello everyone,
I have a surprising message that I do not understand when I boot on the key. This message appears at the same time as the motherboard logo just before reaching the Clover interface.

Would you know that means ?

Perhaps the answer to this question could help me because I am stuck in the installation with the message "MacOS could not be installed on this computer" when I am on the installer and I have found no solution among all those I read on this forum or elsewhere ...

Thank you all for your help.

It is not surprising but expected behaviour.
It is just output from apfs.efi which can be supressed if you want to - Use Search for details.
