attempt to call field 'unpack' (a nil value)

I'm trying to use mpv on MacOS 10.13.6, and I get the following error:

$ mpv myfile.mkv

Your version of Lua doesn't support the standard library function table.unpack. You need either LuaJIT (5.1) with 5.2 compatibility enabled (like the Windows builds), or regular Lua 5.2

Which mpv build are you using?

Seems like the latest commit https://github.com/Ben-Kerman/immersive/commit/d421166136935d7188de00c10dc748d07b4a4c8e solved it for me. Thanks.
