Hey, so I've managed to download the Mac version, and even how to find out the correct process on Chrome using the programming calc dec/hex etc - but unfortunately the 'Open' button is greyed out (on all of the processes) so I can't even open it to move on to the next step. Any help/ideas would be much appreciated - am looking to start getting in to the trophy game, and goodness knows I don't have any legit skillz.
