Hi, Thanks for reply, but the "--check-signature" option in pkgutil was introduced later in 10.7(Lion). So for me the problem remains the same , I am still unable to verify signature on snow leopard and leopard.

Hi all,

I am stuck with an issue that I didn't find any way to verify the productsigned package is whether signed with Apple's Developer ID or not, as I am pushing the flat package silently (Without UI). "productsign" didn't seems to offer me any way to do this or I didn't explored its power yet. I tried using "spctl" that works fine on Lion and Mountain lion, but not on Snow Leopard and Leopard. I want to cover

all OSx from leopard to Mountain Lion.

Thanks, Khushneet
