I was recently inspired to develop a plugin for Illustrator CS6 on my Mac. I've run into a few problems though, because apparently I'm trying to build the plugin in an unsupported environment. I'm using OS X 10.8 (Mountain Lion) and XCode 4.4. Now, I realize that Mountain Lion isn't public yet (I'm an Apple developer so I have access to the prerelease stuff), but regardless, I think that the problem is that I don't have the correct SDK for the development. XCode 4.4 only has 10.7 and 10.8 SDKs with it, and I looked for a XCode 3.2.5 download, but it stopped being supported on Lion. If I have to, I can fetch a copy of 10.5 or 10.6 and develop using it, but I would really like to just use my main machine to do the development. Does anyone have any thoughts on this?
