Can anyone recommend some good books/resources to pick up Mac App development over iOS? So much is focused on iOS, and would like to get some personal recommendations.
Whichever route you take, you _must_ watch any relevant WWDC sessions - they contain a lot of valuable information, and more importantly, in many cases, information that's not available in the docs.
If you want to do Mac dev, I strongly recommend joining lynda.com and watching Simon Allardice's Objective-C and Cocoa programming videos. You can watch all of them in one month, and it will be $25 well spent. Also, there is Lucas Derraugh's very good AppleProgramming channel on YouTube: https://www.youtube.com/user/AppleProgramming
Aaron Hillegass's "Cocoa Programming for Mac OS X" is how I got started. Likely, his new books only focus on iOS development. But this book pre-dates the iPhone. I learned Mac dev from it in 2005. Highly recommended for the basics.
The More Cocoa Programming for OS X: book has been in O'Reilly Rough Cuts beta for several years and the tech is pretty old at this point. Not sure if it ever will see the light of day. The Cocoa Programming for Mac OS X is updated regularly and the training program is ongoing so I imagine it will continue to be updated.
