Mac 4.3 packaged game broken on other Mac

Hi, I was trying to package a simple demo in UE 4.3 for Mac. I can run the packaged game on my Mac fine. But when I copy the packaged game (.app) to another Mac, OSX told me the app was broken. I checked inside the app, there is no MyProjectName.app in /UE4/Engine/Binaries/Mac/. I searched around and found out it used to be a .app file in that directory before 4.3, which required command like “Open -a name.app path_to_pak -pak” argument to run a pak or blueprint game. Did they change the file structure for Mac? Also, did anyone succeed on making a packaged game running on a different Mac?

I think I found the reason - do not use AirDrop to transfer packaged file, even zipped. I guess AirDrop modified permission on transferred files. Anyway the packaged game can run without any problem after I copy them with a USB stick.
