Here's a quick rundown of all the latest and newest stuff that didn't work in 10.7.4 that now works in 10.8 natively. Intel 3rd Generation Core i5/i7 Ivy Bridge CPUs Native kernel and power management support in OS X Mountain Lion Intel HD 4000 Onboard Graphics Use DVI port, and you may have to unplug and replug for full support NVIDIA GeForce 6xx Series Works natively without any injection- use GraphicsEnabler=No Thunderbolt Native support for "Cactus Ridge" controllers. No hotswap support yet- device needs to be plugged at boot. All of this new support is very exciting- we need everyone to test if they have the new hardware, and report their findings. I'm sure we'll make all of this work great with little to no tweaking eventually. Make a new thread in the Mountain Lion forums, or leave a comment here.
