Yes, using "open" works:) However we're actually mounting the dmg from within our app, and doing an "hdiutil attach -nobrowse -noautoopen" to keep it off the Desktop. From there we copy the app inside using NSFileManager. Basically, we're trying not to bother our users about it:) So sticking with hdiutil is important.

Wow, that's crazy that someone asked practically the same (very esoteric!) question on Codermite just a few hours after I posted it here. I haven't tried manually setting the Quarantine flag as suggested in that post. It looks like using xattr to do this is a bit tricky, however I think I'll give it a try just to see what happens. But question back to Quinn: How "safe" would it be to manually set the Qurantine flag, in an attempt to trigger Gatekeeper's "ticket ingestion"?
Without going into too many gory details, the reason I'm looking into this is that our systems currently do a two-pass Notarization: App first, build the dmg, then Notarize the dmg. It'd be nice if we could skip the first Notarization step and just stick with Notarizing the dmg. But we could certainly just stick with a two-pass Notarization system and call it a day:)
