How to make flat NSButton?

Question

How can I make a flat NSButton just like in this picture?

buttons

I think this picture from Mac OS X >= 10.9. I have Mac OS X 10.8.5.

I suspect you may need to subclass NSButtonCell. By the way, I think that picture is of an NSSegmentedControl, not NSButton. — JWWalker

Try removing the border to your button. In interface builder it is a simple check mark in the attributes inspector
