My understanding is that in 2.6.2 it is part of the R.app GUI.  (There is 
a legacy device in package grDevices.)

In that case you don't want a screen device.  There are new versions of 
png() and jpeg() as well as new bmp() and tiff() devices, and they all 
work in pixels and have options to use Quartz (although that is not 
necessarily preferable to the cairo options, depending on how the latter 
work out by release time).

There are a lot of new features in pre-2.7.0, and with it going into beta 
in a bit over a day now is a good time for MacOS users to start trying it
