I'm trying to add a FinderSync Extension in an App which is built using py2app.
py2app does not have a recipe for bundling App Extensions so I created a Cocoa project and added a FinderSync Extension target. After building the appex I copied the appex to the app built using py2app under Plugins folder.
The FinderSync Extension is set to be sandboxed using entitlement file but when I launch the main app I got following message displayed on Console App.
9/17/15 10:33:50.212 AM pkd[309]: ignoring mis-configured plug-in at /Applications/Test.app/Contents/Plugins/TestFinderSync.appex: plug-ins must be sandboxed
I've searched on Stack Overflow but could not find the solution.
What am I missing here?
In order to make it work You should provide the entitlements file from your plugin.
MyPlugin.entitlements
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
</dict>
</plist>
And codesign the plugin with the your cert:
codesign --sign <cert> --entitlements <path to entitlements file> --force <path to bundle>/Contents/PlugIns/MyPlugin.appex
Also, if You are building the plugin from Swift source, make sure bundle up all required Swift*dylibs in Contents/Frameworks
Hope this helps
