Hey guys, I just bought a Razer Deathstalker Essential yesterday and out of the box, it feels and works great when playing Guild Wars 2! However, when I installed Razer Synapse 2.0 on my Macbook Air 2013 13', it keeps telling me to "Please connect a Razer Synapse 2.0 enabled device". I've tried plugging the keyboard on both USB slots but it still won't work. I've also re-installed Synapse a dozen times and nothing seems to work. I've tried to google it, but all the working suggestions are for windows. Since Razer products aren't cheap, I just want to get my money's worth and have all features working on my laptop. For now, this Deathstalker is just an overpriced and oversized ordinary keyboard. If anyone has any idea how to make this work, please tell me. I would be forever grateful to you! Thanks in advance!
