Erreur lorsque j'essaye d'installer Mac OS Monterey sur une clé usb

Bonsoir, j'ai suivi un tutoriel pour installer Mac OS Monterey sur mon Macbook Air mi-2011 non compatible, du coup j'ai téléchargé la maj sur mon ordi et j'ai effacé une première fois ma clé usb (de 16Go) depuis l'utilitaire de disque puis à partir du terminal. Mais lorsque j'ai entré la commande "sudo /Applications/Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/Sans\ titre" et que j'ai confirmé, un message d'erreur apparaît juste après ça : "To continue we need to erase the volume at /Volumes/Sans titre.

If you wish to continue type (Y) then press return: y

Erasing disk: 0%... 10%... 20%... 30%... 100%

Making disk bootable...

Q - " english version : hello, so I followed a tutorial to install Mac OS Monterey on my non-compatible Macbook Air mid-2011 "

A - To perform this action will require booting from a Bootable Installer.

The Bootable Installer can Only be performed on an Apple Computer

This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer.

Example : Bootable Installer of Monterey would have to be done on a computer that Qualifies to run Monterey.

Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.

Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.

english version : hello, so I followed a tutorial to install Mac OS Monterey on my non-compatible Macbook Air mid-2011, so I downloaded the update on my computer and deleted my usb key (16GB) first from the disk utility and then from the terminal. But when I entered the command "sudo /Applications/Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume" and confirmed it, an error message appeared immediately afterwards saying : "To continue we need to erase the volume at /Volumes/MyVolume.

If you wish to continue type (Y) then press return: y
