I just recently got my first mac. I do lots of programming on windows but now I want to get into Mac development. What are some languages i should know or tools i should use to
You could try combining f-script and traditional Cocoa (xcode in other words). f-script is great when you want to experiment with the Cocoa API, which is surely different from what you are used to. The more dynamic you stay, the faster you learn. That is my experience.
