The exploit, posted at XDA Developers, is scripted to run on Windows but i've successfully used it manually from my Mac too. As a test I rooted a couple of ICS devices I have kicking around here (all good), as well as a bootloader locked Nexus 7. Very nice!
If you've been waiting for root for your ICS or newer device (yes, it won't work on Gingerbread) then maybe today is your lucky day. If it does work for you, remember to show your appreciation by donating. Support your devs!
