 As of OS X 10.9 Mavericks, using an Apple-blessed key to sign binaries is a requirement in
 order to satisfy the new Gatekeeper requirements. Because this private key cannot be
 shared, we'll have to be a bit creative in order for the build process to remain somewhat
 deterministic. Here's how it works:

+- Builders use Guix to create an unsigned release. This outputs an unsigned ZIP which
   users may choose to bless and run. It also outputs an unsigned app structure in the form
   of a tarball, which also contains all of the tools that have been previously (deterministically)
   built in order to create a final DMG.
 - The Apple keyholder uses this unsigned app to create a detached signature, using the
   script that is also included there. Detached signatures are available from this [repository](https://github.com/bitcoin-core/bitcoin-detached-sigs).
