Updated to 10.8 and did some refactoring. The save dialogue should work properly now. Still trying to trace the original memory issue. I got CidVilas' code from http://www.thingiverse.com/thing:8262 and compiled it for Lion. I haven't used the old one so let me know if this works. GitHub link: https://github.com/chrisbrent/cocoaKinect UPDATE: At last I have the code upload to github: https://github.com/chrisbrent/cocoaKinect Not sure if it works with Mountain Lion as I don't have it yet. I should be able to look at the crash when saving thing now.Can someone try this for me. It works for me with a Kinetc and 10.7 running through XCode, but I've never built a Cocoa app for distribution beofore.
