Just tested on a MacBook Pro (Retina, 15-inch, Late 2013) and it didn't work. (Although I see in the README it says to run it on an Apple MacBook Air 13-inch, Early 2015). Anyone else get it to work?
Works here on a Retina 15-inch mid-2012 MacBook Pro. You've got to have the antenna real close to the machine (talking 10 cm here), turn the dial pretty much to the end of the AM band and then you can hear the tune through loads of AM static.
Thanks for your feedback. Even different models of the same computer will have different results. But I suspect that the MBPR you have will likely still work. Please check different AM channels and put the antenna directly on the computer to get started. If you find another frequency that works please let me know (email on the project page).
Works fine on my MacBook Pro Retina, 13-inch, Early 2015. Quite a lot of static, but an amazing moment when you do pick out the tune for the first time !
Works for me on an Early 2014 MacBook Air and Mid 2011 iMac, although the iMac signal is very, very weak.
UPDATE: This DID work for me on my MacBook Pro (Retina, 13-inch, Late 2013). Nicely done @fulldecent!
Working on a mid-2012 15" non-retina MBP. I was able to pick up the tune on various frequencies, starting around 650khz and on various other bands right up to around 1500khz (my radio's upper limit).
