I bought a Mac Mini recently, wanting to learn the Mac OS X a bit, and maybe to do some porting work myself for Mac as well. So now I have ported Pogo Sticker to Mac! (requires at least Mac OS X 10.3.9)
If you wonder where did the Porrasturvat – Stair Dismount Mac port come from, Martin Storsjö volunteered to port it, doing a great job with it. Keep an eye open for Truck Dismount… ;-) His work surely helped me a bit with Pogo Sticker as well, showing me a few things to look out when porting software for Mac OS X.
