I just got this keyboard for my mac and I love it. The mechanical keys are a dream.
To answer your question (very late), I've swapped my K70 back and forth between a win 8 machine and a mac and the LED config is definitely saved. There are some issues though, which I'll get to later.
Both Alt and Win keys on both sides of the space bar work and in OSX keyboard preferences I reversed them to act like option and command. The application launcher key I never use, so I have no idea. There are some media keys and volume keys, which appear to work in my experience, except for the Stop button (I guess it doesn't know what to do with that in iTunes, since there is only Play/Pause). There are three corsair specific buttons at the top: one for setting the LEDs (which are all red), one for adjusting the LED brightness, and one lock for disabling the windows key when activated (presumably so you don't accidentally kill your fullscreened game by hitting the start menu button). Both the one for setting LEDs and their brightness work everywhere; I've tested by setting it up on a PC and then plugging it into a mac and it still kept it. Hitting the LED button just switches between your lit configuration and all the keys lit up, so it's not all that complicated. But it works wherever I bring it.
Now, the stuff that doesn't work. There are three white LEDs for the conventional Num Lock/Caps Lock/Scroll Lock states of the buttons. These do not work on OSX. They only work on Windows. Now, there is a manual switch on the keyboard which swaps the OS built into the keyboard, but the configurations are all meant for PC. There is a fall-back mode all the way at the end called BIOS, which is meant as a 'compatibility mode'. I've found that if I set it to this, I can at least get the caps lock LED to show the right state. The num lock/scroll lock LEDs though are stuck as whatever they are, but I don't really care personally, as caps lock is the only one I am actively looking for when I type. If you set it to BIOS though, the windows button locker doesn't work, but I can't imagine why you'd care about that on OSX. For more information on this, I found this thread while googling:
http://forum.corsair.com/v3/showthread.php?t=118346 Funnily enough, when in BIOS mode, Scroll Lock and Pause Break act like the brighten/dim buttons for the screen, so that's kind of an accidental feature for me, since I use those a lot too.
Hope that's helpful,

I would like to know if any of you have the Corsair K70 keyboard and using it on your Mac?
Im interested in knowing if it works correct and if it remembers the lighting scheme you have set in windows?
As in, if I decide it to only light up specific keys, will they then be the only ones light in OSX or will it default to all keys light?
