Building for OS X / no pkg file built

When I Build for OS X, the correct app specific provisioning profile is chosen in the initial Corona Build dialog.

Then I choose “Send to Mac App Store…”

And the next screen asks for an Application identity and an Installer identity.

For both the Application identity and Installer idenity, the dropdown offers two options:

 - None

 - My “3rd Party Mac Developer” certificate

Choosing the 3rd Party Developer for both Application and Installer, I get the error:

ERROR: creating installation package failed: productbuild: error: Cannot write product to “/Users/MyMacPro/Assets/Corona/AppName.pkg”. (Could not find appropriate signing identity for “33F92F99E229B6E64114CAC75CA623BC0CA26611”.)

The Corona docs say to use Application Loader to submit the .pkg file, but after this error, Corona does not build a .pkg file so I have nothing that I can submit. (https://docs.coronalabs.com/daily/guide/distribution/osxBuild/index.html#TOC)

Was using build 2801, then switched to try with 2795 since that was the first build to support Mac OS X submission. Running on a Mac with OS X 10.10.5
 

The app runs well using any other build option: “Open application”, “Create DMG”, “Show in Finder”, and “Do nothing” but I cannot submit it to the App Store.

Any suggestions?  Thanks!

I was unaware that I needed to create both a Mac App Distribution certificate AND a Mac Installer Distribution certificate and choose each of these respectively in the Corona build dialog.

These certificates be created in Xcode… Preferences… Accounts… View Details
