## Short answer

Apple's host for GarageBand downloadable content.

Safe to block

Safe to block if you don't use GarageBand. If you do, its extra sounds and instruments can't download.

Matches

`audiocontentdownload.apple.com`

A name with `*.` covers every name under it: `*.push.apple.com` matches `1-courier.push.apple.com`.

## What it serves

Apple's enterprise host list names `audiocontentdownload.apple.com` in its Apps and additional content section, for “GarageBand downloadable content”.

Sound libraries are large. A download from this host can be big, and it starts when the app asks for more content.

Apple doesn't list other apps for this host.

## What breaks if you block it

Safe to block

Safe to block if you don't use GarageBand. If you do, its extra sounds and instruments can't download.

What breaks if you block it

- GarageBand's downloadable sounds and instruments can't download.

With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s [Protection](https://kilobat.app/docs/blocking#protection) lists.

## Notes

Download extra GarageBand content on your usual network, not on a hotspot.

## Apple’s rules for its hosts

Apple’s list, [Use Apple products on enterprise networks](https://support.apple.com/en-us/101555), says that devices open these connections, not Apple’s servers. Apple services fail any connection that uses HTTPS interception, so a proxy that inspects TLS should leave Apple’s hosts alone.

If a firewall allows hosts by name, allowing `*.apple.com` covers most Apple services, Apple says. A firewall that works only with addresses can allow `17.0.0.0/8` for IPv4, and `2403:300::/32`, `2620:149::/32` and `2a01:b740::/32` for IPv6.

To see which app on your Mac opened a connection to this host, use Kilobat’s Connections tab, or the [agent network log](https://kilobat.app/docs/agents#agent-network-log) for AI agents.
