I use this hack to distinguish between 10.5 and 10.6, since mainQueue is only available 10.6 or later according to Apple's docs:

? (defun snow-leopard-or-later-p ()
    (#/respondsToSelector: ns:ns-operation-queue (objc::@selector "mainQueue")))
SNOW-LEOPARD-OR-LATER-P
? (snow-leopard-or-later-p)
T
? 

warmest regards,

Ralph
