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:

erikng

require 'base64'
require 'plist'

module Chef::Provider::User::DsclMojaveUserExtensions
  # new for 10.14+
  def mac_osx_version_greater_than_10_13?
    Gem::Version.new(node['platform_version']) > Gem::Version.new('10.13.99')
  end

  # updated for 10.14+

erikng

import struct, objc
from Foundation import NSBundle
from Cocoa import NSAppleEventDescriptor

def OSType(s):
    # Convert 4 character code into 4 byte integer
    return struct.unpack('>I', s)[0]

# Create an opaque pointer type to mask the raw AEDesc pointers we'll throw around
AEDescRef = objc.createOpaquePointerType('AEDescRef', '^{AEDesc=I^^{OpaqueAEDataStorageType}}')

# As written, this requires the following:
# - OS X 10.6+ (may not work in 10.10, haven't tested)
# - python 2.6 or 2.7 (for collections.namedtuple usage, should be fine as default python in 10.6 is 2.6)
# - pyObjC (as such, recommended to be used with native OS X python install)

# Only tested and confirmed to work against 10.9.5
# Run with root
