Mac Version works after chmodding the executable (located in .app file /Contents/MacOS. Open the terminal and type sudo chmod a+x ~/Downloads/Peguins\ Diet\ v1.2\ Mac.app/Contents/MacOS/Angy\ Birbs - After doing this right click on the app file and press open, when it shows the security warning click cancel, then do it again and click “open”, this time it should open the game :)
