Script for reliably downloading binaries (e.g. Xcode) from Apple's CDN

xcode-downloader.rb

#!/usr/bin/env ruby

print "What is the URL of your Apple Downloads resource?\nURL:"
url = gets.strip

print "What is the ADCDownloadAuth cookie token:\nADCDownloadAuth: "
token = gets.strip

command = "aria2c --header \"Host: adcdownload.apple.com\" --header \"Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\" --header \"Upgrade-Insecure-Requests: 1\" --header \"Cookie: ADCDownloadAuth=#{token}\" --header \"User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_1 like Mac OS X) AppleWebKit/602.2.14 (KHTML, like Gecko) Version/10.0 Mobile/14B72 Safari/602.1\" --header \"Accept-Language: en-us\" -x 16 -s 16 #{url} -d ~/Downloads"

exec(command)

Awesome! It helps a lot.

I think some MacOS versions broke file-allocation features.

Great, for CN users especially

Brilliant mate.

what is ADCDownloadAuth ? how to get it?

Hey @n0an there’s a write-up here: http://iandundas.com/blog/2017/2/21/script-for-reliably-and-quickly-downloading-xcode-on-a-poor-connection

Hope it helps

This works great!!

I think this no longer works. It gives me a 403 even after providing a valid cookie. Maybe apple has changed the authentication? God knows why.
