Salutations!

I have been enjoying the experience of simultaneously running Linux Mint and macOS on my laptop by utilizing separate external SSD drives for each operating system. The boot loader I’ve been employing is rEFInd. Recently, however, I encountered an issue when attempting to boot into macOS. A message appeared on the screen stating:

“Error: premature end of file /EFI/APPLE/BOOT/BOOTX64.efi.”

Despite my efforts to resolve this problem through online research, I could not find any useful resources addressing this specific premature end error. The solutions provided were more geared towards cases where the mentioned file was missing altogether.

To address the issue, I attempted to use the macOS recovery system. However, upon opening the Disk Utility, the external SSD drive housing macOS was not detected. Only the USB drive containing the macOS installer was visible.

Feeling quite uncertain about how to proceed, any guidance or assistance would be greatly appreciated.
