I've downloaded the demo application and then added a user and started a mission. I finished the typing mission, then quit the game in hope to find the progress folder or file, but the problem is that it saves the progress in a location that's impossible to find. This means you won't be able to transfer the progress and your grandson needs to start again. Mac is different that Windows and even if you've had the progress files, you wouldn't have the possibility to restore them unless the software used a cloud save/restore function which lacks.
