+        # and then adding a binary that unarchives the content and runs them (similar to a self-extracting zip).
+        # The problem is that it locates the start of the archive inside the binary by looking for a specific magic value.
+        # Both binaries (x86_64 and arm64) use the same magic value, so after bundling in a universal binary, the bootloader
+        # will always find the first archive, even if it's the wrong architecture. Thus, only one architecture works.
+        # The binary patch applied below changes the magic value for only one of the binaries, so we have a different
+        # magic value to search for each architecture, which solves the problem.
+        # We need to re-sign the binary afterwards since the signature becomes invalid when tweaking the bytes
