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.

I too am getting the 403...

It's working for me... I followed the instructions in this fork and the script above works fine: https://gist.github.com/manishpathak99/2a18fce18493f460fe80f2bd542a8560

I had a 403, but managed to make it work by replacing https by http.

I've created a macOS tool that you can use to download Xcode and other tools from developer.apple.com with up to 16 times faster (using the multi-connection download). Also, it has resume capability. You can use this if you want to avoid manual work.

Nice!! I will check it next time I download

Saves lifes!

Thank you!

I’m getting this

`ERROR] CUID#7 - Download aborted. URI=https://developer.apple.com/download/more/

Hi all. Can anyone help us working through this?

As of today, for Xcode 11.5 and with redesigned Apple Download pages, we keep on receiving 403.

The cookie should be correct, we tried both straight from Developer Console, as well as with a Firefox Cookie Quick Manager extension, just to be sure: they report the same value, same characters.

The download URL, as of today, looks like (taken from https://xcodereleases.com/):
https://developer.apple.com/services-account/download?path=/Developer_Tools/Xcode_11.5/Xcode_11.5.xip
Not sure if that querystring parameter messes up things (unlikely).

We tried with just http: no luck. We also tried with a forked gist by @manishpathak99: https://gist.github.com/manishpathak99/2a18fce18493f460fe80f2bd542a8560. Same result (also, the script seems the same from a quick look). We also tried to structure the URL as posted in that forked gist (https://download.developer.apple.com/Developer_Tools/foo/bar.xip), again with no luck (actually this URL gives 403 in browser too).

Ok, found issue. Cookie was ok. URL taken from xcodereleases.com apparently was not working for the script.

The right URL is the one taken from https://developer.apple.com/download/more/. It actually has the same structure as posted in the forked gist, so we made some errors before, while trying to make that URL up on our own.

@vineetchoudhary Thanks.
