Click on the LAST download...the one that says Installation Instructions. It will tell you what to do with that .bin file.
For Macintosh Users

download and double click the file again. To check the file size, view "File in Finder" then check the

NOTE..
Yeah done that first of all 2 days ago, still won't open properly. Went into an Apple store today, they told me to right click on the .bin file, tried that but there's nothing new that I've already tried there to open it with. The only thing there just opens another .bin file again.
Looks like I've stumped Mac Forums and the Apple Store lol
