You will have to install two keys and two certificates into your Macintosh keychain, and a provisioning profile into your Xcode and your device.

  1. Join the team. Give you email address to the team agent (Mark Meretzky). He will ask Apple to invite you to join the team. Please RSVP to the email from Apple inviting you to join. Joining the team will let you download your apps to your device without having to pay $99.
  2. Create a Certificate Signing Request (CSR) and your two keys. After you have received email confirming that you are a team member, launch the application Keychain on your Mac. (One space before the uppercase A.)
    Keychain Access → Preferences… → Certificates
    Make sure that OCSP and CRL are both Off. You can then close the Preferences window.
    Keychain Access → Certificate Assistant → Request a Certificate From a Certificate Authority…
    User Email Address:
    (the address you used when you joined the team)
    Common Name: John Doe
    Leave the CA Email Address empty.
    Request is:
    • Saved to disk
    ✓ Let me specify key pair information
    Save As: CertificateSigningRequest.certSigningRequest
    Where: Desktop
    Key Size: 2048 bits
    Algorithm: RSA
    Your certificate request has been created on disk.

    You should now have a file on your desktop with the unwieldly name CertificateSigningRequest.certSigningRequest. As a side effect of creating this file, you should also have two keys, public and private, in your keychain. To make sure the keys are there, go to the Keychain Access window and click on the Keys category in the lower left corner. (You may also have to select login in the upper left corner.) The name of the keys should be the Common Name you specified above.
  3. Submit the CSR. Go to the iOS Provisioning Portal. Enter your Apple ID and password. Click on “Member Center” in the upper right, and then “Certificates, Identifiers, & Profiles” On the left side, click on Certificates. Under Certificates, click on Development.
    Press the plus sign.
    What type of certificate do you need?
    • iOS App Development
    About Creating a Certificate Signing Request (CSR)
    Generate your certificate.
    Upload CSR file.
    Choose file…
    Choose the CertificateSigningRequest.certSigningRequest file on your desktop.
    Press the Generate button.
    Your certificate is pending approval.
    Press the Done button.
  4. Download your certificate. Back at the “Certificates, Identifiers & Profiles” page, the Status of your certificate will be “Pending Approval”. Your team agent will approve your request; he usually checks his email at least once per day. When you get email from Apple, go back to the Back at the “Certificates, Identifiers & Profiles” page. The status of your certificate should be “Issued”. (You may have to press your browser’s Refresh button.) Select your certificate and press the Download button. Go to the directory that holds your downloaded files, probably the Downloads or Desktop subdirectory of your home directory. You should see a new file, ios_development.cer.
  5. Install the certificate into your keychain. Double-click on the ios_development.cer files to install it. To make sure it is installed, go to the Keychain Access window and click on the Certificates category in the lower left corner. You should see a certificate named “iPhone Developer: Your Name (serial number)”. (You may have to make the Name column wider to see the serial number.) The certificate should have a triangle in front of it. Click on the triangle and you should see your private key. You can then discard the CertificateSigningRequest.certSigningRequest file on your Desktop.
  6. Register your device. This is something that your team agent will have to do for you. The name that he uses for your device will be your GitHub name. Our examples will use the dummy name abc1234. You will have to give him the Device ID (the “UDID”) of your device, consisting of 40 hexadecimal digits. (The 16 possible hexadecimal digits are 0123456789abcdef.) One way to discover the Device ID is to plug your device into your Mac and then launch the application
    Window → Devices
    Select your device and look under Device Information for the 40-character identifier. Another way to discover the Device ID is to launch iTunes. In the left panel, click on your device. In the right panel, click on the Serial Number and it will change into your 40-character identifier. After your team agent has registered your device, go to the iPhone Provisioning Portal. On the left side, click on Devices. Under Devices, click on All. You should see your device and your 40-character identifier in the list of devices.
  7. Create an App ID. We can all use the same App ID, the one named mm64. To see the App ID named mm64, go to the iPhone Provisioning Portal. On the left side, click on App IDs.
  8. Create a Provisioning Profile. This is another thing that your team agent will have to do for you. He will do it when he registers your device, if you have already joined the team. Go to the iPhone Provisioning Portal. On the left side, click on Provisioning. Under Provisioning, click on All. Select your provisioning profile. After a while, the status of your Provisioning Profile will change from Pending to Active. (Refresh the page to update the status.) You can then press Download. Your download directory will contain the file abc1234.mobileprovision. Launch Xcode. Drag the abc1234.mobileprovision file onto the Xcode icon in the dock. To make sure that the provisioning profile is installed into Xcode,
    Window → Devices
    In the left panel, control-click on your device and select Show Provisioning Profiles….
