Hi,

as i didn't find a binary package for Mac OS X I created my own ;-)

I've built wx.NET for Mac OS 10.5.7. I used wxWidgets 2.8.10 and created a Mac OS X Framework Bundle.
The zip file includes a "wxWidgets.framework" folder, which must be installed into /Library/Frameworks/ on the root partition of MacOS X. I also tried to copy the wx.NET.dll to Mono's GAC (/Library/Frameworks/Mono.framework/Versions/2.4/lib/mono/gac/wx.NET/0.8.0.0__c5f483f7e93d2714), but mono can't find the wx-c.dylib. But I think it is ok, that users can just put the wx.NET files into their bin/debug/release folders.

I hope you can put this on your site, so that other mac os users don't have to install 3GB only for the necessary dev tools to build wx.net themselves!

The best way to distribute sucha mac os build would be to use an Installer that copies over the Framework to the right place, but I've never done this before.
