HelperTool + XPCService Project Setup

This is how to set everything up (I believe)

The original Apple Doc for this project can be found in README-APPLE

In this example the 3 identifiers for the 3 targets are

Name	Identifier
Broker (Main app)	com.blackwellapps.Broker
BrokerHelper (HelperTool)	com.blackwellapps.BrokerHelper
XPCService	com.blackwellapps.XPCService

1 Add Copy File build phase

Main App Add Copy File build phase to main app target: Destination: Wrapper Subpath: Contents/LibraryXPCServices, Codesign on Copy:Disable.

XPCService Add Copy File build phase to XPCService target: Destination: Wrapper Subpath: Contents/Library/LaunchServices, Codesign on Copy:Disable.

2 Modify Info.plists

XPCService-Info.plist (Tools owned after installation)

Add a new key value pair to the XPCService's Info.plist

• Key: "Tools owned after installation"
• Type: dictionary

Inside this new dictionary add a another key value pair:

• Key: Your helper's bundle identifier
• Type: string
• Value: "anchor apple generic and certificate leaf[subject.CN] = Certificate Name and certificate 1[field.1.2.840.113635.100.6.2.1] / exists /"

HelperTool-Info.plist (Clients allowed to add and remove tool)

Add a new key value pair the HelperTools's Info.plist

• Key: "Clients allowed to add and remove tool"
• Type: array

As this is an array, we will add a new item to the 0 index:

• Key/Position: "Item 0"
• Type: string
• Value: "identifier XPCService identifier and anchor apple generic and certificate leaf[subject.CN] = Certificate Name and certificate 1[field.1.2.840.113635.100.6.2.1] / exists /"

3 Developer ID

Choose Developer ID:* in Code Signing Identity in build settings for each targets.

Main App

XPCService

HelperTool

---

4 Build

Build the app.

5 SMJobBlessUtil.py

Use SMJobBlessUtil.py cli script

Update Info.plist:

Format: $ ./SMJobBlessUtil.py setreq <XPCService path> <XPCService's Info.plist path> <Helper's Info.plist>

./SMJobBlessUtil.py setreq Build/Products/Debug/com.blackwellapps.XPCService.xpc XPCService/XPCService-Info.plist BrokerHelper/HelperTool-Info.plist HelperTool/HelperTool-Info.plist

Check Code Signing status:

Format: $ ./SMJobBlessUtil.py check <XPCservice path>

./SMJobBlessUtil.py check Build/Products/Debug/com.blackwellapps.XPCService.xpc

---

Troubleshooting

• If it doesn't pass the CLI check then make sure #3 is correct
• Also Make sure each .plist file is set as Info.plist in the corresponding Target's Build settings.
