Well, work has been interfering with xLights development lately. But in the last week, I have made some progress. I am getting close to having the Mac version working. The new Mac release will be OSX 10.5+, 32-bit, Intel only. Windows and Linux will be supported too, of course. Behind the scenes, I have upgraded wxWidgets to version 2.9.3, mostly for Mac compatibility reasons. Hope to have something to share in about 2 weeks.

PS. I am still waiting on my Raspberry Pi. At this point, I'd say the chances are about 50/50 that I will have one running xLights by the time the Academy rolls around.
