grub-file: Check if a file is an x86_64 XNU image (Mac OS X kernel).
$ grub-file --is-x86_64-xnu ${filename}
try on your machine
The grub-file command is a utility used with the GRUB boot loader to analyze binary files, particularly bootable kernels and operating systems.
In this command, --is-x86_64-xnu is an option that checks if a given file is an x86_64 (64-bit Intel/AMD) kernel for the XNU operating system, which is the kernel used by macOS, iOS, and other Apple operating systems.
${filename} is a placeholder for the actual file you want to analyze. You would replace it with the path to the file you want to check.
So, when you run this command with a specific filename, it will determine if the file is an x86_64 XNU kernel or not.
