Your mind is fine – you’ve just been using Cocoa for so long that you can 
predict what API are probably available :)   In this case, there probably 
*should* be such a method, a wrapper around -[NSWindow endSheet:] which plugs 
in self.sheet, but in this case, Apple let you down.

One more tidbit to anyone else making the conversion to the new block-based 
methods.  For some reason, Xcode warned me about a dozen or so NSApp 
beginSheet:::: methods being depredated but not about the NSApp endSheet:: 
methods which are also deprecated in 10.10.  In a hurry, I updated the former 
but not the latter.  Whoa!  It looked good in initial testing, but then I found 
that a dismissed sheet would *reappear later* after a different sheet was 
shown!  Lesson: When you update your beginSheet:::: methods, update the mating 
endSheet:: methods too.
