Install instructions for MacOSX:
• Requires a wired full sized keyboard. (Note to developers: you should probably choose a key mapping that works on MacBooks, they are really popular.)
• After download, locate the MacNoEditor folder in your Downloads folder and open it. To run the first time, hold down Control as you double-click unrealProject.app. Click OK to run it.
• After the first time, it will run normally with double-click.
