Howdy,

I'm getting

$ time texlua collatz.lua 1 1000000
837799

real	0m17.333s
user	0m17.119s
sys	0m0.014s

using the x86_64-darwin (for macOS 10.10 and later) and TL 2017 (almost not pretest?).

Is there a reason you can't update to macOS 10.10 (Yosemite) and then use x86_64-darwin?

PS: I get

$ time lua collatz.lua 1 1000000
837799

real	0m19.021s
user	0m19.007s
sys	0m0.008s

with lua 5.3.4 on the same system.

Good Luck,
