I want to replay the back to the future game series but cannot install the first episode. I use Chrome and Safari to download it and the episode needs to be "unzipped" before I can play it.
But if I downloaded the file from Chrome, nothing happens when I double click the unzipped app. And when I download it from Safari, the unzipped file shows an error before the game can even start.
I'm running a Macbook pro, 2013 with Mountain Lion.
