Thanks @lupyuen  so I still managed to download the wrong toolkit two more times, oops!    but I think this is the correct one:

Code:

arm-gnu-toolchain-11.3.rel1-darwin-x86_64-aarch64-none-elf.tar.xz

but I get an error with that (added to PATH thanks):

Code:

dyld: Symbol not found: ____chkstk_darwin
Referenced from: /Users/peter/Development/ArmGNUToolchain/arm-gnu-toolchain-11.3.rel1-darwin-x86_64-aarch64-none-elf/bin/aarch64-none-elf-gcc
Expected in: /usr/lib/libSystem.B.dylib

I think everything else is now configured correctly, apart from the toolchain.  As I mentioned, it is an older macos (10.12.4) and hence my Zig is also older version (0.8.1) not that I got that far yet but just for context.
