Having trouble opening packaged project on Mac

So I’ve cooked the content. Packaged the game (no issues so far) however when I click on the app to open. It either takes an incredibly long time to open, freezing the computer or it simply doesn’t open at all.

The game is only able to be player on a Mac as that’s what I packaged it as atm.

There’s a link below to my dropbox where you can download it. It would be much appreciated if someone could have a look and help me with my problem.


Hi JamesSwann95,

I was able to open your game without issue other than a security warning from which I could easily surpass. Could you post your System Specs?

The Specs of the system I tested this on are:

  • MacBook Pro (Retina, 15-inch, Late 2013)
  • OSX 10.12
  • PROCESSOR: 2.3GHz Intel Core i7
  • GRAPHICS: NVIDIA GeForce GT 750 M 2048 MB

I’m running mine on the latest MacBook Pro. (2016)

When you try and open the app, check System Preferences>Security & Privacy> Allow apps downloaded from: and see if there is an error there preventing the app from opening. Make sure you do not have security software scanning the app (unidentified and from a third party)

Are you trying to open the app with other programs open in the background, particularly UE4? If so, try closing all other apps to see if there is a significant opening time. (I’m clicking on the sample app with Editor open and it opens immediately/instantly.)

Lastly, if you have another Mac available from a friend, family member, etc. try opening there to compare results I expect they will need to grant security permissions as described above, but after that, it should open right up.

Please try the above and respond with your results.
