Alright, I reuploaded builds, please tell me if you can run it now!
The 64bit one has the same issue, but the 32bit one says it has to be updated!
I see, I have contacted the engine developer, hope we can fix this issue, please stay tuned, sorry for the inconveniece!
No worries! Thank you for your help
Got a response from developer: "unfortunately ALL Mac apps that haven't been signed with an Apple licensed key show that "can't be opened" message, please try following:right-click (or Cmd-click) on the app and select Open"
