find one. Does one just use [NSView display] and hope?

Well, drawing is now done by Quartz, a client-side library, so you don't have a bunch drawing commands sitting in a communications buffer waiting to be sent to the WindowServer for execution. However, I have found that flushing the current graphics context ( [[NSGraphicsContext currentContext] flush]; ) and/or flushing the current window can help in certain situations.

I wanted to check my usage in a sample program just now but found that I had managed to eliminate all manual flushing. Chances are you actually don't need to flush either.
