I absolutely dislike the smart-phone looks which were introduced at Yosemite 2. my SSD is nearly saturated and I won't engage into risky system upgrade I can imagining updating to a more recent macOS, but won't do only to resolve a luatex binary issue. > > 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. OK, thanks. I had forgotten to say that I had tested with Lua 5.2 on my system as well (don't remember the minor minor number) and got similar result as with Lua 5.3.3, which are a bit faster than the TL2016 texlua I expect other mac os users will be with x86_64-darwinlegacy. A possibly 100% slow-down of luatex is perhaps not a big deal if it happens only in directlua code. Best, Jean-François
