I started some days ago a small Mac app for Mac OS X Lion. I've never uploaded a Mac app before, so this is the very first time.
This is what I've already done:
Now I wanted to "Share" the Application. Xcode (4.1 btw) said to me, there were no valid signing identities. Does I need to add an Entitlement.plist like in iOS? Have I forgotten something?
Update:
I just figured out, that I have to sign my app twice. I've still selected "3rd Party Mac Developer Application" but I can't select the Installer cert while submitting my app.
I got it to work. I deleted my App and created it new.
I didn't create a new Configuration, and I only changed the Code Signing Indentity of the Target to 3rd Party Mac Developer Application. After this, I archived the app and then I was able to select the installer cert.
