Managing Certificates and Provisioning - Xcode 4 - page 274

1. If you don't already have a CSR file, create it using the instructions earlier in this chapter.
2. Create a unique App ID using the Developer Certificate Utility.
Figure 11.26
The Developer Certificate Utility is much simpler than the iOS equivalent.
3. Create the App Software certificate using the Developer Certificate Utility.
This step uses your CSR file. Download the certificate, but don't install it yet, even though the Utility tells
you to.
4. Create an Installer Package certificate.
This step uses the App ID. Download the certificate, but don't install it.
5. If you don't already have the extra WWDR certificate, download it.
6. Install the certificates in your keychain.
You can now use the certificates to create a distribution build with an installer package and upload the in-
staller package to the App Store. The certificates are valid for a year, or until your developer subscription ex-
pires, whichever is shorter. They're not linked to a specific App ID, so you can use the same certificates for
all your projects.
Creating an App ID
To create an App ID, follow these steps:
1. Select the Create Mac App ID link, and fill in the two fields, as shown in Figure 11.27.
2. The name is an arbitrary string.
