@@ -65,3 +65,18 @@ Background images and other features can be added to DMG files by inserting a
.DS_Store before creation. The easiest way to create this file is to build a
DMG without one, move it to a device running OSX, customize the layout, then
grab the .DS_Store file for later use. That is the approach taken here.

As of OSX Mavericks (10.9), 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 gitian to create an unsigned release. This outputs an unsigned
dmg 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.
- Builders feed the unsigned app + detached signature back into gitian. It
uses the pre-built tools to recombine the pieces into a deterministic dmg.

Wait for OSX detached signature:
Once the OSX build has 3 matching signatures, Gavin will sign it with the apple App-Store key.
He will then upload a detached signature to be combined with the unsigned app to create a signed binary.

Create the signed OSX binary:
pushd ./gitian-builder
# Fetch the signature as instructed by Gavin
cp signature.tar.gz inputs/
