Just found this today for those that are looking for it:

There is a link to the URL to download the package file.

@roadrunner2348][/url Thank you for posting that, however that link is referring to Garageband 6. I found the link long ago, but forgot to come back and post its location.

The core content that installs on first launch can be found at http://audiocontentdownload.apple.com/lp10_ms3_content_2013/MAContent10_GarageBandCoreContent.pkg

.

Download and install Charles Proxy
http://www.charlesproxy.com

Open Charles Proxy
Enter an admin password
Start Recording
Open GarageBand for the first time
In Charles Proxy click on the Structure tab
Open the http://audiocontentdownload.apple.com folder

I found these

@msblake Thanks for correcting that, I guess that's what I get for being in a hurry. Thanks for update!

Hey all,
There also used to be a garageband Extra content package as well as the basic package. Does this exist for the new garageband 10 as well?

I like the solution very much - thank you!
I found

http://audiocontentdownload.apple.com/lp10_ms3_content_2013/MAContent10_GarageBandPremiumContent.pkg

So, aside from downloading all these and comparing them, does anyone know if the link @msblake posted is the entire package or must we get it in pieces based on all the other links above?

I'm wondering the same as @boettchs - which packages are really needed in order not to get the initial question? I tried snapshotting as well as recording, but it didn't seem to catch all that's needed.

If you're snapshotting you may need to add the package receipts in /private/var/db/receipts to your Composer package for GarageBand to see that those content packages have been installed.
