Greetings,
The other option is simply to take advantage of Avid Link:

You should be able to simply log into your Avid account within the Avid Link application (access it from your Mac toolbar on the top of the screen), then simply tell the app to automatically install everything (you simply need to put in your Mac credentials once) you are entitled to, then go make a coffee and let it do the work, including downloading and installing everything for you.
