Hi David,

Sounds like you have not certified your installer.

I use packages which does that step for me.

However when the resulting installer is downloaded from a website, the checks that Apple is doing as part of the download process is resulting in the installer being quarantined, and the only way to release it is to run the terminal command.  Frustrating.
