So, I’m learning how to program on OS X. As mentioned previously mentioned I’m using Aaron Hillegass’ Cocoa Programming for Mac OS X. I’m using the 2nd edition and Aaron has a 3rd edition coming out soon. I’m looking forward to it as I’ve been having to work through and figure out what changed from Tiger ((OS X 10.4)) to Leopard ((OS X 10.5)). It’s been good and challenging, but nothing unbearable. Today I ran across documentation on the changes to Leopard one needs to know to use the book. Sweet!
