Building on Mac, packaging errors

I am trying to package things up on the Mac and have been hitting two roadblocks.

When I select Package->Mac I get an error about a missing SDK and to use the “Launch On” menu, which doesn’t seem to exist. When I use the FrontEnd, I get the error:

RunUAT ERROR: AutomationTool was Unable to run successfully. Exited with code 6.

there is precious little information on doing Mac builds and configuring the system. Any tips?

Same problem here. Did you manage to fix it?
