This is an i386/x86_64 fat binary version of nvramdump, built for macOS 10.6+.

It is bundled into the OpenCore Utilities/LogoutHook release folder in favour of the CI-built x86_64/arm64 10.9+ compatible version, since 32-bit support and 10.6+ support is relevant to users of this utility.

Future updates to nvramdump.c will require this to be rebuilt manually, which can be done on an Xcode version which supports 10.6+ and i386 with FATBIN32=1 make.
