Hi reid,

I was so excited to know there's a solution out there for my Air A - FINIALLY!

However, I got problems when building the kext on my Lion 10.7.2 / Xcode 4.2!

It goes something like this:

Tried to build in on my iMac (late '07) / Lion 10.7.2 / Xcode 4.2; the first error is still there but the second on is gone.

Please help!

Hey.

I no longer use this software: my MacBook Air Rev. A lives in a box.

I'd debug the error messages. IIRC, I was using GCC to compile this software instead of Clang. There is quite a bit of deprecated code in this extension so I'm not too surprised that newer compilers are choking on it.
