How to Change Open Files Limit on OS X and macOS

This text is the section about OS X Yosemite (which also works for macOS Sierra) from https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/#mac-os-x

The last time i visited this link it was dead (403), so I cloned it here from the latest snapshot in Archive.org's Wayback Machine https://web.archive.org/web/20170523131633/https://docs.basho.com/riak/kv/2.1.4/using/performance/open-files-limit/

Mac OS X

To check the current limits on your Mac OS X system, run:

# A module that will turn functions annotated with `@async :true` into functions
# that return a function that does the original function. For async goodness.
defmodule Magic do
  defmacro __using__(_env) do
    quote do
      Module.register_attribute(__MODULE__, :async_register, accumulate: true)
      @on_definition Magic
      @before_compile Magic
    end
  end

let process = Command::new("randomstrings").stdin(Stdio::piped()).stdout(Stdio::piped()).spawn().unwrap();
let mut thing = process.stdout.unwrap();

loop {
    let something: &mut [u8] = &mut [0];
    thing.read(something);
    print!("{}", std::str::from_utf8(something).unwrap())
}
